Firstly, Fire Alarm Controller
Before debugging, all external control lines of the fire alarm
controller should be cut off, and the power should be switched on
after connecting the fire detector of any bus circuit and the manual
fire alarm button and other components on the bus circuit.
According to the relevant requirements of the fire Alarm Controller
standard, the following functions of the controller shall be checked
and recorded one by one by means of observation and instrument
measurement, which shall meet the following requirements:

3. 1.Self-check function and operation level
Make the connection between the controller and the detector open
or short, and the controller should send fault signal within 100s
(except fire alarm signal in case of short circuit);In the fault state,
make the detector in any non-fault part send fire alarm signal, the
controller should send fire alarm signal within 1min, and record the
fire alarm time;Then make other detectors send fire alarm signal to
check the controller’s alarm function again.
2.Mute and reset functions
Make the connection between the controller and the standby power
cut off or short. The controller should send a fault signal within 100s.
3.Check shielding function
Short-circuit any point within the protection scope of the bus
isolator and check the isolation and protection function of the bus
isolator.
4.Make at least 10 fire detectors on any bus circuit in the state of
fire alarm at the same time to check the load function of the
controller.
5.The automatic conversion function of main and standby power
supplies, and the inspection of article 4 shall be repeated under the
condition of standby power supply.
6.Other functions specific to the alarm control panel

4. 7.Connect the other loops to the fire alarm controller in turn and
repeat the inspection
Secondly, point type smoke and heat detector
1. Check the alarm function of each fire detector one by one by
using the special detection instrument or the method of simulating
fire. The detector should be able to send fire alarm signal.
For unrecoverable fire detector, simulated alarm method should be
adopted to check its alarm function one by one, and the detector
should be able to send fire alarm signal.When there are spare parts,
can sample check its alarm function.
2.The alarm function of each household fire detector shall be
checked one by one by means of special detection instruments, fire
simulation or pressing the detector alarm test button. The detector
shall be able to send sound and light alarm signals, and the
connected detector shall send sound alarm signals.

5. Thirdly, linear type heat detectors
Simulate fire alarm and fault on the unrecoverable detector, check
the fire alarm and fault alarm function of each fire detector one by
one, and the detector should be able to send fire alarm and fault
signal respectively.The recoverable detector can be made to send
fire alarm signals and simulate faults by means of special detection
instruments or fire simulation. The fire alarm and fault alarm
functions of each fire detector can be checked one by one. The
detector should be able to send fire alarm and fault signals
respectively.
Fourthly, linear beam smoke detector
Adjust the optical regulating device of the detector one by one, so
that the detector is in the normal monitoring state. Block the optical
path with the optical dimmer of 0.9dB, and the detector should not

6. send fire alarm signal. Block the optical path with a dimmer rate
(1.0dB ~ 10.0dB) set by the product manufacturer, and the detector
shall send fire alarm signal. Use a dimmer with a dimmer rate of
11.5dB to block the optical path, and the detector should send fault
signal or fire alarm signal. When selecting reflection-type detector,
the detector should be checked at 0.5m in front of the detector
according to the above requirements, and the detector should
respond correctly.
Fifthly, line sampling suction smoke fire detector
Add test smoke one by one into the sampling hole at the end of the
sampling tube (the most unfavorable place), and use stopwatch to
measure the alarm response time of the detector. The detector or
its control device should send fire alarm signal within 120s.
According to the product manual, the airflow of the sampling tube of
the detector is changed to make the detector in a fault state. A
stopwatch is used to measure the alarm response time of the
detector. The detector or its control device should send a fault
signal within 100s.
Sixthly, point fire detector and picture fire detector
The detector’s alarm function should be checked one by one in the

7. most unfavorable part of the detector’s monitoring area by special
detection instrument or fire simulation method, and the detector
should be able to respond correctly.
Seventhly, Manual fire alarm button
Apply appropriate thrust to the recoverable manual fire alarm
button to make it act, and the alarm button should send out fire
alarm signal. For the unrecoverable manual fire alarm button, the
method of simulating action should be adopted to make the alarm
button act (when there are spare parts, the action test can be
conducted by sampling), and the alarm button should send out the
fire alarm signal.
