Maintenance procedures for fire equipment power monitoring systems

Fire equipment power status monitor

■ main, standby power failure, first check the power inlet terminal, power supply should be normal, such as loose battery cable should be tightened to connect the cable terminals, the fuse should be replaced fuse;

■ printer failure, first check the print paper should be installed correctly, sufficient, manual test print function does not print should be replaced when the printer can be manually printed but not automatically printed.

■ printer failure, first check the print paper should be installed correctly, sufficient, manual test print function does not print should be replaced when the printer, can be manually printed but not automatically printed, should be repaired or replaced printer.

Voltage/current signal sensor

■ power supply interruption power supply, with a multimeter to measure the sensor acquisition voltage is normal, such as voltage is normal, then replace the sensor, such as no voltage, then replace the insurance;

■ power supply over-voltage, under-voltage, the sensor should be installed correctly.

■ power supply overvoltage, undervoltage, check the sensor input voltage and sensor display voltage, such as inconsistency is required to calibrate the sensor display voltage, or replace the faulty sensor.

Maintenance procedures for fire equipment power monitoring system

Fire equipment power status monitor

■ Inspection requirements:

1. Quarterly inspection of the monitor's appearance and cabinet interior, there should be no damage, deformation, rust and corrosion;

■ Inspection requirements.

2. Quarterly check the monitor terminals should be firmly connected; 3.

3. Measure the power supply voltage of the sensor at the end of the monitor bus circuit with a multimeter every quarter, which should be in line with the requirements of the manual.

4. Check the monitor battery every year.

■ Maintenance methods:

1. with a vacuum cleaner, damp soft cloth, etc. to remove dust inside and outside the cabinet, with compressed air, brush, etc. to remove the cabinet circuit boards, terminals at the dust, air humidity can be placed in the cabinet desiccant; 2. tighten the loose wiring.

2. tighten the loose terminals, replace the corroded screws, terminal gaskets and other connecting parts, remove the corrosion of the wire end, tin-lined reconnection; 3.

3. Replace the circuit board or adjust the line when the power supply voltage value of the sensor at the end of the monitor bus circuit is less than the value specified in the manual; 4.

4. Batteries should be maintained in accordance with the requirements of the manual.

Voltage/current signal sensor

■ Inspection requirements:

1. quarterly inspection of the sensor appearance, there should be no damage, deformation, corrosion; 2. quarterly inspection of the sensor wiring.

2. Quarterly check the sensor each terminal should be connected firmly.

■ Maintenance method:

1. with a special cleaning tool or soft cloth and appropriate cleaning agent to clean the sensor parts pollutants, cleaning the sensor after the voltage / current value calibration to the actual measurement value;

■ Maintenance methods.

2. Tighten the loose terminals, replace the corroded screws, terminal spacers and other connecting parts, remove the corroded wire ends, tin-lined and reconnected.

Fire equipment power monitoring system end-of-life conditions

Fire equipment power monitoring system equipment life of no more than twelve years; if you continue to use the relevant provisions of GB 28184 should be carried out annually in accordance with the function of the test, the inspection can be used only after passing. The intelligent management level of the cultural relics and ancient buildings inside and around the fire and security status monitoring, fire and security to achieve unified management.
