NxtGen Emergency Services Communications

Next Generation Emergency Services Communications 

New Delhi: In the blink of an eye, emergencies can change lives. What if help was just a message away at such times? The next-generation Emergency Response Support System (ERSS) being introduced by govt of India in a few months is poised to revolutionise the way we reach out to police in times of crisis.
This new system promises to bridge the gap between citizens and law enforcement. The state-of-the-art ERSS will allow users to connect with police via WhatsApp by sending messages to a dedicated number that will be integrated with the ERSS-112 call taker module.
"The system will support a range of communication channels, including voice calls, SMS, email, web and even IoT devices, ensuring that users can reach out for help in the way that is most convenient for them and even if a voice call is not possible," an officer said.
According to the cops, the new system will also tackle the perennial problem of busy signals and failed connections, thanks to upgraded technology and increased server capacity. This means that users will be able to reach police quickly and efficiently, even in times of high demand.

NFPA 1225: 2022 - Standard for Emergency Services Communications

🔧 Effective emergency services communications is the backbone of resilient and professional emergency response. Before focusing on NFPA 1225 let's have a look and summarise NFPA 1221, which has now been replaced by NFPA 1225 (2022 edition), but firstly we'll look at NFPA 1221 (2019 edition) as it was the last edition before the consolidation.

Supersession by NFPA 1225

🔧 NFPA 1221 has been consolidated into NFPA 1225, which now includes broader requirements for Emergency Services Communications and Dispatching Systems, combining elements of NFPA 1221 and others like NFPA 1061 (Professional Qualifications for Public Safety Telecommunications Personnel).

🔧 NFPA 1225 (2022) — provides technical guidance that directly relates to fire and emergency responders, particularly in terms of communications, safety, operational efficiency, and responder support.

1. Reliable Communications Backbone

Relevance to Responders:

  • Ensures resilient, interoperable communication systems between dispatch centers and field personnel.
  • Mandates redundancy in voice and data pathways (radio, LTE, IP-based systems) so responders are not cut off during incidents.

Technical Provisions:

  • Radio system coverage must achieve 95% in-building coverage for critical areas (e.g., stairwells, basements).
  • Two-way radio functionality is required in all buildings as part of Emergency Responder Radio Coverage Systems (ERRCS).

2. Call Handling & Dispatch Standards

Relevance to Responders:

  • Sets expectations for how quickly fire/rescue calls are processed and units dispatched.
  • Improves situational awareness through structured call interrogation and priority-based dispatching.

Technical Provisions:

  • 90% of emergency calls must be answered within 15 seconds.
  • Dispatchers must use standardized protocols to relay accurate incident type, hazards, access points, and responder needs.

3. Emergency Responder Radio Coverage Systems (ERRCS)

Relevance to Responders:

  • Ensures that firefighters, EMS, and police have uninterrupted radio communication inside complex buildings, tunnels, and remote areas.

Technical Provisions:

  • Requires in-building signal boosters (BDAs) and testing to validate coverage.
  • Mandates annual testing of ERRCS in all new and existing buildings where systems are required.

4. Interoperability Across Agencies

Relevance to Responders:

  • Promotes seamless communication during multi-agency responses — critical in large-scale incidents (e.g., MCI, wildfires, high-rise fires).

Technical Provisions:

  • Supports P25-compliant radio systems and shared communication protocols.
  • Encourages pre-planned talkgroup assignments for mutual aid and regional response.

5. Responder Accountability and Safety

Relevance to Responders:

  • Enhances real-time location tracking, PAR (personnel accountability reporting), and distress signals.
  • Improves dispatcher-responder feedback loops for changing incident conditions.

Technical Provisions:

  • Integration with fireground telemetry (e.g., PASS devices, thermal imaging feedback).
  • Support for incident commander radio override in critical conditions.

6. Cybersecurity and System Resilience

Relevance to Responders:

  • Protects critical communication infrastructure from being disabled during response.

Technical Provisions:

  • NFPA 1225 requires ECCs to implement cybersecurity policies, firewalls, and redundant systems.
  • Includes disaster recovery protocols to maintain continuity in communications during large-scale events.

7. Training and Performance Evaluation

Relevance to Responders:

  • Ensures that dispatchers and ECC personnel are trained to support incident command and tactical communication.

Technical Provisions:

  • Includes integrated training requirements for public safety telecommunicators (from NFPA 1061).
  • Requires QA/QI programs to monitor call handling and improve future performance.

Key Takeaways

  • NFPA 1225 = NFPA 1221 + NFPA 1061 + modernization for NG911 It reflects the evolution from a technical systems standard to a comprehensive emergency communications operations standard.
  • NFPA 1225 introduces three integrated pillars:

Technology – CAD, radio, IP-based systems, infrastructure.

Personnel – Qualifications, training, and performance expectations.

Policy and Practice – Response time standards, QA/QI, continuity of operations.

What is more, ERSS will feature automated area services, using location-based services (LBS) and Google emergency location service to pinpoint the caller's location. This will enable the cops to respond with precision and speed even when the caller is unable to provide his or her location.

The existing ERSS system, in operation since 2019, will be upgraded to include modern communication features. This older version relied primarily on traditional communication channels. While functional, the system lacked several modern features crucial for an optimised emergency response.

The new system includes expanded features such as WhatsApp, ChatBot support, media crawl capabilities and integration with Internet of Things (IoT) devices, offering a richer range of communication options for victims. Initially, the call taker collected vital information manually through forms. With the updated system, however, this process is much more streamlined, incorporating Speech-to-Text technology, allowing the call taker's voice to be converted into text automatically.


"Additionally, the system now includes advanced capabilities to identify and merge repeat calls, ensuring that the same incident isn't mistakenly handled multiple times," a police source said. Parallelly, the dispatcher module has also been enhanced with intelligent features that facilitate faster dispatching of emergency response units (ERUs), which include the fire department and other important services.

ERUs have been upgraded with advanced technology to improve their response. Previously, they used GPS tracking through mobile devices. Now, they have dedicated GPS trackers for better location tracking, multiple internet connections for reliability, and special software for device management. "It will have another feature to track movements of ERUs towards the incident spot," a source said.

The Geographic Information System (GIS) used by the system has been significantly enhanced. The new GIS map combines data from multiple sources, including OpenStreetMap, the Survey of India, Google and Here Maps, making it more accurate and comprehensive than ever before.


"This advanced mapping tool ensures that dispatchers have a clearer, more detailed view of the incident locations, allowing for faster decision-making and more precise routing of emergency services," a police source said. Location identification has also been improved. The system still relies on traditional cell tower triangulation (LBS) to pinpoint a caller's location. However, the integration of Google ELS ensures better accuracy and faster location marking, allowing emergency teams to respond to incidents more efficiently.

Emergency Response Support System (ERSS) is a Pan-India single number (112) based emergency response system for citizens in emergencies. Each State/ UT is required to designate a dedicated Emergency Response Centres (ERC) to handle emergency requests. If you require emergency assistance from Police, Fire & Rescue, Health and other services, you may :

1.   Dial 112 from your phone;

2.   Press power button on your smart phone 3 times quickly to activate Panic call;

3.   In case of feature phone, long press ‘5’ or ‘9’ key to activate Panic call;

4.   Log on to State ERSS website and place your SOS request;

5.   Email SOS alert to State ERC; and

6.   Use 112 India Mobile App (available in Google Playstore and Apple store) to activate a panic call to ERC.

🚨 Why Emergency Responder Radio Coverage (ERRCS/BDA) Systems Are Critical in Modern Buildings 📡🏢

In today’s high-density, steel-and-concrete buildings, radio signals often struggle to penetrate deep indoors — leaving emergency responders with little to no communication during a crisis. That’s where BDA (Bi-Directional Amplifier) systems come into play.

🔧 The Engineering Behind the System:

1. A Donor Antenna placed on the roof captures a clear signal (DAQ ≥ 3.0) from the public safety Radio Repeater outside the building.
2. The BDA unit boosts this signal and distributes it through DAS (Distributed Antenna System) antennas across all floors.
3. These DAS antennas provide coverage in signal-challenged areas like stairwells, basements, and mechanical rooms, ensuring DAQ ≥ 3.0 throughout.
4. The system also supports bi-directional communication — signals from inside the building are boosted and sent back to the radio network

📐 Why It Matters:
Without ERRCS/BDA systems, responders face dead zones that can delay emergency actions, endanger lives, and violate NFPA 72/1225 and IFC code requirements.

✅ New buildings (especially high-rises, hospitals, and large commercial structures) must design for full radio coverage, ensuring:
1. 95% coverage across all areas
2. 99% in critical zones like stairwells and fire command rooms

🚀 Modern Alternatives to Traditional BDA/ERRCS Systems – What’s New and Better?

As buildings get smarter, so do emergency communication systems. While traditional BDA/ERRCS systems are vital, modern systems bring new advantages:

1. Fiber-Based DAS – Stronger, cleaner signal across large buildings using fiber instead of coaxial cables.
2. Cloud Monitoring – Remote access, real-time alerts, and easier maintenance from anywhere.
3. Public Safety + Cellular Integration – One system handles both emergency radios and commercial cellular (LTE/5G), saving space and cost.
4. Smart System Management (SNMP) – Integrates with building systems for better monitoring and faster response.
5. 5G Emergency Platforms – Faster, more reliable communication for first responders in smart buildings.
6. Longer Battery Backup – Keeps systems running even during power outages, exceeding code requirements.
7. AI-Powered Design Tools – Smarter planning, quicker installs, and optimized coverage with AI support

✅ These upgrades make in-building communication more reliable, easier to manage, and future-ready.
Any designers involved in building design, construction, fire/life safety engineering — this is not optional; it's a life-safety necessity.!

To ensure uninterrupted connectivity, the supervising officers can now monitor the health of servers and network components across the entire system. One of the most notable updates is the introduction of enhanced National Support Services (NSS), which were previously unavailable. The system improves access to common services such as LBS, SMS, interstate data sharing, and statistical reporting. Key features now include central and state-level portals with dashboards, a national GIS map, access to telephone subscriber data, a directory of verified and emergency contact numbers, and better interoperability for communication across states.

Changes in BS 5839-1 2025 Ed

Changes in BS 5839-1 2025 Ed

BS 5839-1:2025 Fire Detection and Fire Alarm Systems for buildings - Part 1: Design, installation, commissioning, and maintenance of systems in non-domestic premises - Code of practice.

As of 30 April 2025, BS 5839-1:2017 has been officially withdrawn and replaced by BS 5839-1:2025, bringing a range of important changes to fire detection and alarm systems in non-domestic premises across the UK. Whether you're overseeing fire safety in a care home, school, office block, or hotel, it's essential that you understand the implications of this revised standard.

The focus of the standard is system design; it does not dictate whether a commercial premises requires a fire detection and fire alarm system - that is determined by legislation such as Building Regulations. Its purpose is to provide comprehensive recommendations and guidance on planning, design, installation, commissioning and maintenance of fire detection and fire alarm systems. This British Standard does not apply to domestic premises, that is detailed in Part 6 which is due for review soon.

It is also important to note that while the standard is a code of practice and takes the form of recommendations, Clause 6 sets out which of these recommendations it is "considered unacceptable" not to adopt. 

While the technical requirements in the latest version remain largely consistent, the content of the 2025 revision has been refined and reorganised to provide greater clarity, more structured guidance and updated references.

Key changes in the 2025 revision include:

·        Updated terms and definitions to bring them in line with the newly published fire vocabulary standard, BS 4422:2024

·        The siting recommendations for manual call points have been simplified 

·        Stairway lobbies are now covered with automatic detection

·        Improved guidance on fire detection in sleeping areas

·        Clarification of the period between service visits to acknowledge that it is not always possible to carry out routine maintenance of a fire detection and fire alarm system on exactly the same day every year.

What is considered a Non-Domestic Property?

In the UK, non-domestic properties are buildings not used solely as private dwelling. This includes offices, shops, schools, factories, care homes, and mixed-use premises. They’re subject to specific regulations like the Fire Safety Order 2005, requiring clear fire safety responsibilities.

What’s changed in BS 5839-1:2025?

This 2025 edition introduces a number of structural and practical updates across three key areas:

1. Design and Installation Updates

·        Detection in New Areas: L4 systems now require detection at the top of lift shafts; L2 systems now account for sleeping risk in addition to risk-assessed rooms. Smoke detectors are now clearly preferred over heat detectors in bedrooms or sleeping areas (e.g. care homes, student accommodation, hotels) to ensure faster detection.

·        Lift Shafts: Category L4 systems must now include detection at the top of lift shafts, improving response time in vertical escape routes.

·        Manual Call Points: Placement guidance has been strengthened, emphasising accessibility in occupied zones.

·        Lockdown Alarms: These can now be integrated into fire alarm systems but the tone must be distinct from fire alarm tones.

·        Ceiling Obstructions: Clarified guidance on how to handle obstructions like ductwork or closely spaced beams to avoid any potential interference with fire alarm and detection systems.

·        Monitoring Times: In Category L systems, signal monitoring must occur within 90 seconds, with faults recognised within 3 minutes.

·        Battery Calculations: BS 5839-1:2025 has updated the battery backup calculation formula. Review battery backup capacity, especially for older panels or large systems, to ensure compliance with the new calculation method. See Annex E (normative) page 149.

·        Red Mains Cables: The requirement for fire alarm mains cables to be red has been clarified.

·        Prohibited Variations: Items like zone charts and remote monitoring in care homes can no longer be treated as variations.

·        Low-Risk Lobbies: Detection is now required in low-risk lobbies, such as toilet lobbies, depending on the specific system type. If you're unsure then make sure to speak to your fire safety consultant who should be able to provide clarity.

·        New Panel Notice: In an attempt to help reduce false fire alarms, fire alarm panels must now display a new label:
“FALSE ALARM NOTICE: This fire alarm has an active connection to the fire and rescue service”

·        Updated Language: You'll notice some terminology changes, such as 'care homes' now being referred to as 'residential care premises' and 'fire service' as 'fire and rescue service'. 

2. Maintenance and Servicing Updates

·        Recording Variations: All variations from the standard must be logged in the site’s fire alarm logbook.

·        Engineer CPD: Competent persons carrying out maintenance must now engage in continual professional development (CPD). Ventro are proud to offer CPDs and if you would like to attend or book a specific CPD session.

·        Control Panel Clocks: These must be checked and corrected at every service visit to ensure accurate event logging.

·        Logbook Requirements: All deviations from BS 5839-1 (e.g., exceptions, placement compromises) must now be clearly documented in the site’s fire alarm logbook.

·        Battery Marking: Engineers are now permitted to write the battery fitted date directly on the battery with a marker.

·        Service Intervals: Still required every 6 months, but there's new flexibility, regular services can now occur every 5 to 7 months without being non-compliant.

·        Clock Synchronisation: The control panel clock must be checked and adjusted at every service.

·        Zone Charts: These must be verified during every maintenance visit to ensure they are up to date and correct.

·        Removal of Redundant Equipment: Old detection devices, call points, and interfaces must be removed if no longer in use to avoid any potential confusion in an emergency. Redundant devices must be completely removed, not just disconnected.

·        Interface Accessibility: Interfaces must be fully accessible, hidden panels are no longer acceptable.

3. Certification and Documentation Changes

·        Updated Certification Templates: Due to widespread paragraph renumbering, all certificates based on model forms in BS 5839 must now be updated, even if the clause content hasn't changed.

·        New Section 7: A dedicated section for extensions and modifications makes it easier to adapt existing systems compliantly.

·        Restructuring of clauses: Clause 4 is moved to the Introduction, and Clause 33 is merged with Clause 31.

·        Standard Terminology: Terms such as “care homes” are now “residential care premises,” and “fire service” is now referred to as “fire and rescue service.”

4. Enhanced Safety Measures

With a growing focus on inclusive safety, the following updates aim to protect a wider range of building occupants:

·        Visual Alarms: Greater emphasis is placed on visual alert devices (VADs), essential for deaf or hard-of-hearing users.

·        Zone Plans: Clearly displayed zone plans are now required in multi-zoned buildings, especially those with sleeping risks.

·        Automated Alerts: In residential care settings, systems must automatically notify a monitoring centre when triggered, speeding up emergency response.

5. What You Need to Do Now

If you’re responsible for fire safety in a commercial or residential care setting, you should:

·        Review and Update: Audit your current fire detection and alarm system. Check whether the design, devices, and documentation still comply.

·        Engage Competent Professionals: Use certified fire alarm designers, engineers, and maintainers who maintain CPD, such as those BAFE SP203-1 registered.

·        Update Documentation: Revise your certificateslogbooks, and maintenance records to reflect the 2025 standard and any site-specific deviations.

·        Communicate Changes: Inform all stakeholders—staff, contractors, and residents—of relevant updates to fire procedures and system layout.

6. What about the cable?

The sections have also been renumbered, for example Section 26: Cables wiring and other interconnections, is now Section 25

Section 25: Cables, wiring and other interconnections (formerly Section 26) has retained the core principle of maintaining circuit integrity during a fire. This requires that all cables must ensure interconnections between elements of both fire detection system and fire alarm systems and that they must operate for an appropriate length of time.

The level of a cable's fire resistance is referred to as "standard" and "enhanced", terms originally introduced back in the 2002 version of BS 5839-1. These requirements have remained the same in the 2025 revision. 

A word of caution to those responsible for system maintenance: while there is nothing in the new revision that requires older systems to be brought in line with the new standard, it is necessary to maintain and service an existing system to the new standard.
