The fire control cabinet shows the main electrical fault. What's the matter?
1, fire power equipment are dual loop power supply.2, you refer to the fire control cabinet should be fire alarm linkage controller.3, fire alarm linkage controller adopts the electric power supply and storage battery power supply controller with floating charge.4, now the controller reported the main electrical failure as follows:4.1, the city power shortage.4.2, the controller power supply disk, the main fuse fuse.4.3, the controller power supply part of the fault.
1, the main power failure2, the main power and fire control cabinet connection may be a problem, resulting in power failure
Usually because of fire fighting equipment need to double circuit power supply, to ensure that there is power in case of fire, so the fire control cabinet and main electric power, the main power off after main power failure, and will immediately switch to the standby power (power is usually battery, or second way power).When the main power failure is shown, it is important to grasp the cause, check the equipment and restore the power supply.
