4.0 DEFINITION
FACP – Fire Alarm Control Panel, MFACP - Main Fire Alarm Control Panel
MCP - Manual Call Point
5.0 METHOD OF WORK
5.1 Material
5.1.1 None
5.2 Tools & Testing Equipments
(a) Drilling Tools
(b) Hand tools
(c) Multi-tester (Continuity And Voltage Tester)
5.3 PRE COMMISSIONING PROCEDURE
Checking system wiring:
5.3.1
Ensure that no power is applied to the 4100ES fire alarm panel and that all
wiring is properly connected.
5.3.2
Use the green grounding Plug in the control panel for all measurements to
ground. Each circuit must test free of all grounds and extraneous voltages.
Use the volt/ohm meter to check each circuit type.
At the control panel, locate wires from each initiating device or indicating
appliance circuit.
Check each circuit for extraneous voltage by setting the volt / ohm meter to
300VAC. The meter must read 0 volts.
Set the volt / Ohm meter to 60 VDC. The measurements must read 0 volts.
Set the volt / ohm meter to OHMS X 10 and check the circuits using resistance
measurements in following table. Locate and correct any abnormal conditions at
this time.

Check all other system wiring to verify that each circuit is free of grounds and
extraneous voltages
5.4 Commissioning procedure
5.4.1
Smoke detector- Apply SOLO Aerosol in the smoke detector chamber until red
LED glows steady
5.4.2 Heat detector – Switch on and place the heat generator covering the detector
until the red LED glows steady.
5.4.3 Manual Call Point – Open the MCP using Simplex key.
5.4.4 Sprinkler Flow switch – Open the Test drain valve until FACP receives FIRE
signal. (Sprinkler Supplier coordination required).
6.2 Graphics work Station.
Programming Method
a.)
b.)
Insert AutoCAD Graphic pages in the system.
Place the device icon in each page.
c.)
d.)
Map the icon with the particular device address
Save the page
Testing method
a)
b)
c)
Simulate any device in the field.
Ensure the graphic screen pop-up with the simulated device.
Click on the flashing device to acknowledge.
6.3 Telephone jacks shall be tested as follows:
6.3.2
6.3.3
6.3.4
Insert the portable handset into the Telephone Jack.
Panel buzzer will activate with flashing LED of the corresponding staircase.
The person near the panel shall pull out the phone from its cradle and receive the call
by pressing the switch next to the flashing LED.
6.3.5 Check for the voice audibility & clarity.
6.3.6 When the conversation ends remove the portable phone from the jack and put the
phone back into the cradle. Press the switch again to cancel the call.
6.4 Function test of devices shall be carried out loop by loop (randomly) as
follows:
6.4.2
6.4.3
6.4.4
6.4.5
6.4.6
6.4.7
6.4.8
6.4.9
Activate the devices described in 6.3.1. one by one.
Function test will annunciate to the following panels: 1. Main FACP, Repeater panel,
Graphic PC .The annunciation includes panel buzzer, LCD display of location and
graphic pop-up in the PC.
Check whether the signal is going to the public address system in case of fire
condition.
Check whether the sounders and flashers are functioning.
If the test result is successful, move to the next device and continue the test up to the
consultant’s or CM’s acceptance.
If the “Alarm Silence” button is pressed, it will stop all audible & visual notifications and
an “ALARM SILENCE IN PROGRESS” message will show in the FACP prior to stop the
appliances.
If the “SYSTEM RESET” button is pressed, “SYSTEM RESET IN PROGRESS”
message will display and reset will take place. Alarm will be cleared after a successful
reset or the panel will show a message that “ALARM PRESENT, SYSTEM RESET
ABORTED”.
An “All speaker evac” toggle button is assigned in the FACP to play the evacuation
message in the building without disturbing the control modules of other interfaces.
6.5 Function test of the Interfaces.
Verify all interfaces are functioning in case of activation of corresponding
initiating devices.
Test shall be carried out in the sequence of loop by loop. It will be tested by
activating any detector or break glass in the loop and verify the following effects are
taken place.
It will be tested by activating one device in the building Also, one Manual Call Point
will be operated in each floor.
6.6 History Log
After successful testing of entire system a historical log shall be generated and
printed for review and comments for inspectors.
6.7 WALK TEST
The system has a Walk test feature which allows a single person to test the
devices. Walk test enable will show as a trouble warning in the system and will be
cleared after successful exit of walk test. Walk test events also will be recorded in
Main FACP. System will reset itself after every device test.
6.8 Witness Demonstrations / Completion
After the successful commissioning the results will be recorded on the testing
and commissioning sheets attached with the document.
5.5 Safety
5.5.1
All appropriate safety personal protective equipment shall be worn by workmen
such as Helmet, cover all clothing, safety shoes, goggles and gloves whenever
required.
5.5.2 Only approved scaffoldings and safety belts can be used on high level works.
5.5.3 All works will be done with the presence of safety officers.
