Functional Testing of Smoke, Heat & CO Detectors
Functional testing of detectors has long been required by both detector manufacturers and international codes and standards. Leading fire codes and standards such as BS: 5839 and NFPA 72, clearly describe the frequency at which testing must be carried out and the type of tools that should be used.
This
methodology should be applied in accord with IS2189 and relevant International,
National and State standards, as well as the National Building Code.
1.
Functional Testing of Smoke Detectors
1.1 Every
detector must be functionally tested within a 1 year period.
1.2 Every
detector must be tested using equipment and products approved by the detector
manufacturer to ensure compatibility with the detector and in accord with the
manufacturer maintenance recommendations/instructions.
1.3 The
equipment and products used in the testing must not involve the use of naked
flames, flammable oils or toxic substances, to avoid additional fire risk and compromise
of the fire detection system.
1.4 The
testing equipment used should include lightweight, non-conductive, extendable
access poles, which allow the testing to be carried out from a safe position,
without the need for additional access equipment, such as ladders, platforms,
scaffolding, etc.
1.5 Every
smoke detector must be functionally tested by a method which confirms that
smoke can enter the detector chamber from an external source and produce a fire
alarm signal (e.g. by use of apparatus which generates simulated smoke or
suitable aerosols around the detector). It must be ensured that the material
used does not caused damage to, or affect the subsequent performance of, the
detector.
1.6 Products containing substances of an adhesive nature, such as silicones must not be used.
2.
Functional Testing of Heat Detectors
2.1 Every
detector must be functionally tested within a 1 year period.
2.2 Every
detector must be tested using equipment and products approved by the detector
manufacturer to ensure compatibility with the detector and in accord with the
manufacturer maintenance recommendations/instructions.
2.3 The
equipment and products used in the testing must not involve the use of naked
flames, flammable oils or toxic substances, to avoid additional fire risk and
compromise of the fire detection system.
2.4 The
testing equipment used should include lightweight, non-conductive, extendable
access poles, which allow the testing to be carried out from a safe position,
without the need for additional access equipment, such as ladders, platforms,
scaffolding, etc.
2.5 Every
heat detector must be functionally tested to demonstrate that heat can enter
the detector chamber from an external source and produce a fire alarm signal.
2.6 The equipment/product used for the functional heat detector test must use a controlled and directed heat source to avoid compromising the functionality of the sensor and ensuring no damage to the detector casing.
3.
Functional Testing of Carbon Monoxide Fire Detectors
3.1 Every
detector must be functionally tested within a 1 year period.
3.2 Every
detector must be tested using equipment and products approved by the detector
manufacturer to ensure compatibility with the detector and in accord with the
manufacturer maintenance recommendations/instructions.
3.3 The
equipment and products used in the testing must not involve the use of naked
flames, flammable oils or toxic substances to avoid additional fire risk and
compromise of the fire detection system.
3.4 The
testing equipment used should include lightweight, non-conductive, extendable
access poles, which allow the testing to be carried out from a safe position,
without the need for additional access equipment, such as ladders, platforms,
scaffolding, etc.
3.5 Every
carbon monoxide fire detector must be functionally tested to demonstrate that
carbon monoxide can enter the detector chamber from an external source and
produce a fire alarm signal (e.g. by use of apparatus which generates carbon
monoxide or a gas which has a similar effect on the electro-chemical cell as
carbon monoxide). It must be ensured that the material used does not cause
damage to, or affect the subsequent performance of, the detector
3.6 The
equipment/product used must not produce concentrations of carbon monoxide that
exceed the international, national or state standards for safety and protection
