HyperTerminal Settings For Fire Alarm Control Panels

HyperTerminal Settings For Fire Alarm Control Panels

Hyperterminal is a great way to connect to a fire alarm control panel(FACP).  It is also the preferred method to achieving a fire alarm control panels device parameters f you cannot access the program.  Simply connect your laptop to the fire alarm control panel with the appropriate cable and enter the correct values for HyperTerminal.  Once in, your laptop will mimic the FACPs screen or display.  From here you can capture the text file making it easy to store fire alarm testing reports and device parameters.

Here is a little trick if you need to know exactly what devices are on each loop.  While connected with Hyperterminal, pull off each SLC circuit one at a time.  Your laptop screen will then start to display every device on that loop as they go into trouble due to the lack of communication with the FACP loop card.  Capture the text file and your done.  You now have a simple starting plan to re-write a program if necessary.

Below are some of the HyperTerminal settings I have come across:

Difference between XLPE and PVC Cables

Difference between XLPE and PVC Cables

XLPE - is cross linked polyethylene cable. 

Main Thumb rule for differentiation is that XLPE cables can be used for both HT and LT lines.
But PVC Cables can be used only for LT lines.

XLPE can withstand a higher temperature than PVC without detriment. This means that more current can be conducted for the same cross sectional area of copper. This means a big saving in cables costs. 

XLPE Cables useful properties are:-

1. Temperature resistance
2. Stress rupture resistance
3. Environmental stress crack resistance
4. Resistance to U.V light
5. Chemical resistance
6. Oxidation resistance

XLPE Cables can be useful for following applications:-

1) XLPE cables work for the working voltage of 240 V to 500 KV .
2) Conductor Material can be either Copper or Aluminum.
3) XLPE cables can be either Single Core cables or Multi core cables depending upon the number of
cores.
4) They can be Unarmoured or Strip Armoured or Wire Armoured or Tape Armoured type depending upon the presence or absence of Armour.
5) HT / LT Aerial Bunched Cables


Polyvinyl chloride Cables useful properties are :-

They are commonly abbreviated as PVC, insulated cables are widely used in various fields.
PVC's Cables are generally have following Properties:-
1. Low cost
2. Chemical resistance
3. High tensile strength
4. Better flexibility

For, electric cables the PVC is mixed up with plasticizers.
Low voltage copper conductor PVC cables are extensively used for domestic home appliances wiring, house wiring and internal wiring for lighting circuits in factories, power supply for office automation, in control.
PVC CABLES
1) Power Cables upto 1.1 KV
2) Multicore Cables upto 61 Cores
3) Sheilded instrumentation Cables
4) FRLS / FR / HR / Fire Survival Cable

Summary: cross linked polyethylene insulation cable in the electrical performance, heat resistance, physical and mechanical properties, resistance to climate and toxicity are better than PVC insulated cable.

Reasons Why XLPE is Popular
Here are five reasons why XLPE are popular than standard wires available in the market.
  1. Excellent Mechanical and Physical Properties: XLPE has high thermal resistance and higher melting point than most standard cables found in the market. These cables possess low tan delta, high initial dielectric strength, low dielectric strength, and improved mechanical properties at high temperature. Also, XLPE resists moisture, UV light, oxidation, environmental stress, stress cracking, and rupture.
  2. Lightweight: The XLPE wire is lighter than other standard wires with a paper or lead insulation. That’s why it is more convenient to install and transport. XLPE wires are largely used in the construction industry because they reduce transportation and installation costs.
  3. Easy to Maintain: XLPE wires require lesser maintenance, when compared to other standard cables. Also, they have easy jointing and termination procedures.
  4. Used for HT and LT Lines: XLPE wires can be used for both HT and LT lines.
  5. Flexibility: XLPE wires have multiple cores, which makes them highly flexible. This added flexibility contributes to smaller bending radius as well.



Recently XLVLDPE (Cross Linked Very Low Density Polyethylene) wires have been introduced to the market.  These wires have enhanced physical and mechanical properties than regular XLPE wires. The above-mentioned factors and XLVLPDE wires depict the rising popularity of XLPE wires in the market.
