Method Statement for Fire Alarm System (FAS) Installation,
Testing and Commissioning
Following is the method statement for the installation, Testing & Commissioning of the Fire Alarm
System (FAS) which can be altered for a various type of systems like Very Early Smoke Detection
Apparatus (VESDA) or High Sensitivity Smoke Detection (HSSD) etc. The steps are very familiar
and should be personalized and build upon the project-oriented demands, terms and applicable

Wiring & Connections Requirements
 Double-Check that hardware and devices are Nationally Recognized Testing Laboratory (NRTL)
listed for use with Fire Alarm System (FAS) before making connections. Make Addressable
Connections (AC’s) with a Supervised Interface Device (SID) to the Following devices and systems.
Then Install the Interface Device (ID) less than 3 feet from the device controller (DC). When such
Feedback is available at the device or system being controlled, make an addressable confirmation

Fault Finding in Fire Alarm Systems(FAS)
DC Power Charger Faults: (Battery)
Battery (DC Power Oriented) Charger Faults that can emerge during the operational lifetime of an FACP.
You may observe one of the below-mentioned faults:
 Charger 2% out of range.
 Battery Charger Supply (BCS) incorrect to correctly measure the output voltage you will require
to follow the steps mentioned below.
 To prevent infect to the system, disconnect the DC power immediately (batteries & power down
the system, disconnect the power & harnesses from the Power Supply).
 Connect the Multi-meter to the battery leads (with batteries disconnected}, power up & measure
the voltage. Calculate the difference between the measured voltage & 27.6v.
Remember: After 90 seconds approximately, the voltage will drop to <24v. If this happens, power down
& start again.
Positive/Negative Earth Ground Faults:
Fire Panels can detect positive or negative Earth Ground Faults. An Earth Ground Fault occurs when an
electrical circuit is shorted to ground
