The method for eliminating fire alarm controller coupling type faults mainly includes the following steps :
Youdaoplaceholder0 Press the mute key : When the fire alarm controller gives an alarm sound, press the mute key first to stop the alarm sound.
Youdaoplaceholder0 Check and repair faulty equipment :
Youdaoplaceholder0 Fire detector failure : Check for detachment or poor contact between the detector and the base, retighten or replace the faulty bus or detector, repair or replace the interface board.
Youdaoplaceholder0 Main power failure : Check if the mains power is off, reconnect the main power line, replace the fuse or fuse.
Youdaoplaceholder0 Backup power failure : Check if the backup power is damaged or has insufficient voltage. Make sure the backup power is in good contact with the main unit. Replace the fuse or fuse.
Youdaoplaceholder0 Communication failure : Check the communication lines between the area alarm controller and the centralized alarm controller, repair open circuits, short circuits or poor ground contact, and replace or repair the communication interface board.
Youdaoplaceholder0 Shielding isolation and recovery : If the fault involves an external control device such as a detector, module or fire display panel, it can be temporarily shielded and isolated. After the repair, the shielding isolation can be removed and the system can be restored to normal operation.
Youdaoplaceholder0 Suggestions for preventing interlocking failure of fire alarm controllers include :
Youdaoplaceholder0 Regular maintenance and servicing : Regular comprehensive inspection and commissioning of the fire protection system to ensure all functions are functioning properly, extend the service life of the equipment and reduce the possibility of failure.
