The entire fire alarm circuit reports a fault, which will reply later and then report again. What is the cause? Below, the manufacturer of the fire alarm system will explain to you specifically

1. Grounding or short circuiting of circuit lines

Grounding or short circuiting of the circuit line can cause the fire alarm host to report a circuit fault. The reason is that grounding or short circuiting of the circuit will affect the power supply of the entire circuit line.

Troubleshooting method for fire protection circuit: Check the circuit and solve the problem of short circuit or grounding in the circuit.

2. Individual external devices damaged

Individual external equipment damage, such as smoke detectors, manual alarm buttons, fire control modules, and other external equipment damage, can cause unstable circuit voltage and lead to circuit failures.

Troubleshooting method for fire protection circuit: troubleshoot external equipment faults and replace damaged external equipment.

3. Damaged or loose circuit board

Sometimes, poor contact between the circuit board and the card slot can cause the system to fail to recognize the circuit board or damage the circuit board, resulting in circuit failure.

Troubleshooting method for fire protection circuit: Remove the circuit board and reinstall it to ensure that the circuit board is damaged
