Fire automatic alarm facility Fire alarm controller detection Trigger the self-check key to perform functional self-check on all indicator lights, monitors and sound devices on the panel.Cut off the main power supply and check the status of the standby DC power supply and the main and standby power supply.Make any circuit, power supply or internal circuit of the controller in a state of failure, observe the sound and controller, light the alarm fault signals location of and the type indication.During the fault alarm period, the fire alarm is simulated. The controller should send out the fire alarm signal within 1 minute, and then make other detectors send out the fire alarm signal. The controller can alarm again. Detection of Fire Linkage Controller Operate the self-check key and perform functional self-check on all indicator lights, monitors and sound devices on the panel.When the main power supply is cut off, the standby power supply should be put into use automatically, and the state of the main and standby power supply can be displayed correctly.When the connection between fire- fighting linkage input/output control module is equipment open or and short- circuited, it should be able to send out sound and light fault signals which are obviously different from fire alarm signals within 100 seconds. Acceptance Requirements for Automatic Fire Alarm System 1) The main and standby power supply conversion tests were conducted 1-3 times. 2) All the controllers are checked. 3) In this case, there are more than 100 fire detectors and manual alarm buttons, so the sampling ratio is 10%-20%, and the hydrant button sampling ratio is 5%-10%. Acceptance Requirements for Fire Alarm Controller 1) The side distance from the door shaft to the wall should not be less than 0.5m and the front operating distance should not be less than 1.2m. The main power supply should be directly connected to the fire power supply, and the use of power plugs is strictly prohibited. 2) To check the function of fire alarm controller.Including: checking the self-check function and operation level; testing the circuit breaking and short circuit of each circuit, the controller should send out the fault signal within 100 seconds; in the state of failure, the detector of any non-fault part should send out the fire alarm signal, the controller should send out the fire alarm signal within 1 minute; so that no fewer than 10 fire detectors in any bus circuit are in the state of fire alarm at the same time.
