Fire alarm controller detection

The fire alarm controller is the main functional component equipment of the automatic fire alarm system. How should fire detection perform functional checks on the fire alarm controller 1. Cut off all external control wires of the fire alarm controller, and connect the fire detector and manual fire alarm button of any bus circuit to the power supply, so that the controller is in a normal monitoring state 2. Conduct debugging and inspection on the following main functions of the controller, and record them. The functions of the controller should comply with the current national standard "Fire Alarm Controllers" GB 4717 ① Self check function. The controller should be able to perform functional self checks on indicator lights, displays, and audio devices ② Operation level function. The controller should set different operation levels based on different objects used ③ Shielding function. The controller should be able to shield the specified components and illuminate the shielding indicator light, displaying the address annotation information of the shielded components ④ Automatic conversion function of main and backup power supplies. After the main power of the controller is cut off, the backup power should be able to automatically switch on; After the main power is restored, it should be able to automatically switch on; The main and backup power fault indicator lights should be able to correctly indicate the fault status of the controller's main and backup power ⑤ Fault alarm function, including backup power supply wiring fault alarm function and matching component wiring fault alarm function. When there is an open circuit or short circuit in the wiring between the controller and the backup power supply, the controller should emit a fault sound and light signal within 100 seconds, indicating the type of fault. When the wiring between the controller and on-site components is disconnected, the controller should display the type and address annotation information of the faulty component within 100 seconds ⑥ Short circuit isolation protection function. When the bus is in a short-circuit state, the short-circuit isolator can isolate the devices connected to the short-circuit bus. The number of isolated devices should not exceed 32, and the controller should display the address annotation information of the isolated components ⑦ Fire alarm priority and secondary alarm function. Make any non faulty fire detector or manual fire alarm button emit an alarm signal, and then make another non faulty detector or manual alarm button emit a fire alarm signal. The controller should emit a fire alarm sound and light signal within 10 seconds, and display the type and address annotation information of the alarm signal emitting component ⑧ Load function. Multiple fire detectors and manual alarm buttons are in the fire alarm state at the same time, and the controller should record the alarm time of the fire alarm signal components separately. Place at least 10 fire detectors and manual alarm buttons connected to the circuit in a fire alarm state, and check the fire information recording of the controller; When the total number of input and output modules is less than 50, make all modules in working state. When the total number of modules is more than 50, make at least 50 modules work simultaneously. Check the recording of controller startup information

⑨ Silence and reset functions. The controller should be able to manually eliminate the alarm sound signal. After the detection area of the alarm detector is restored and the manual alarm button is reset, the controller should be able to reset the alarm status of the controller, detector, and manual alarm button, and eliminate the sound and light alarm signals; The fire linkage controller should be able to reset the working status of the output and input modules, eliminate startup, feedback sound, and light signals

The fire alarm controller is sequentially connected to other circuits to ensure that the controller is in a normal monitoring state. When in standby operation, check the fault alarm function, short circuit isolation protection function, load function, and reset function of the connection components of the fire alarm controller
