Tests on installed equipment
Preparation
¨
Check to ensure
access
will be provided to areas where installed equipment is to be
tested, such as locked or secure areas.
¨
Ensure all sensor
dust covers
are removed from sensor devices.
¨
Tests may be made easier by having: sensor extractor tool, smoke poles, smoke
canister, heat gun, beam obscuration filter, sensor removal kit and MCP test key, plus
keys to open system equipment.
Site occupants
¨
Before undertaking any of these tests and to prevent unnecessary building evacuation,
ensure:
•
all affected personnel on the site are informed, via a responsible person that the
fire alarm system is being commissioned.
•
where there is a link to an alarm receiving centre, the appropriate action should be
taken to ensure they are informed that tests are being carried out on the system.
S-Quad Sensors
¨
Each S-Quad should be tested for correct operation in the event of fire.
¨
The Sound and Speech part of the S-Quad should be checked to ensure each device
outputs the correct signal at the appropriate volume level and ensure the strobe
operates at the required flash rate.
¨
The sound levels in the areas should be tested in accordance with the British Standard
requirements and to meet the site specific needs as agreed with the customer.
&
1. When testing heat sensors DO NOT use a heat gun for the test in a hazardous
environment.
2. Recommended test equipment and methods must be used to fire test flame
detectors off interface unit.
4. When smoke testing fire sensors using artificial smoke, avoid excessive spray
to prevent accumulation of sticky residues on sensor, see instructions on the
smoke canister.
5. The beam sensors should be tested using obscuration filters to simulate
smoke at default sensitivity.
The BS5839:Part 1 recommends that all sensors are tested for correct operation.
¨
Unless otherwise instructed all sensors should be tested.
¨
Each sensor should also be checked for any physical obstacles that would inhibit the
operation of the sensor in the event of a fire.
¨
Where practical, each
conventional flame detector
operating via an interface unit
should be functionally tested.
Manual Call Points
¨
Each
call point
should be tested for correct initiation of a fire event.
