Fire Alarm System Maintenance Techniques 10

The fire alarm system is composed of a trigger device, a fire alarm device, a linkage output device and other auxiliary function devices, which has the ability to produce smoke, heat, flame and other physical quantities generated by combustion in the early stage of the fire, and turns them into electrical signals through the fire detector, which is transmitted to the fire alarm controller, and at the same time shows the location and time of the fire, so that people can find the fire in time, and take effective measures in time to extinguish the initial fire and minimize the loss of life and property caused by the fireSo how to maintain the fire alarm system in the community?

1. Detector false alarm, detector failure alarm. Reasons: unreasonable selection of detector sensitivity, excessive ambient humidity, excessive wind speed, excessive dust, mechanical vibration, long use time of the detector, decline of device parameters, etc.

Solution: Select the detector with appropriate sensitivity according to the installation environment, avoid the tuyere and the channel with large wind speed during installation, check it regularly, clean and replace the detector according to the situation.

2. Manual button false alarm, manual button fault alarm. Causes: The button has been used for too long, the parameters have dropped, or the button has been artificially damaged. Solution: Regular inspection, timely replacement of damaged ones, so as not to blind the operation of the system.

3. Alarm controller failure. Reason: The mechanical device itself is damaged and the fault is reported or the external detector and manual button problem cause the alarm controller to report the fault and report the fire alarm. Solution: Use the table or self-diagnostic program to judge and check the machine itself and eliminate the fault.

4. Line failure. Causes: Damaged insulation, loose joints, excessive ambient humidity, resulting in a decrease in insulation. Treatment: Check the degree of insulation with a table, check the joint, and use welding, plastic sealing, etc. when wiring.

5. The voltage stabilizing device is started frequently. Reason: Mainly there is leakage at the front end of the wet device, there will also be leakage of plumbing parts or connections, leakage of closed sprinklers, and failure to close the end of the venting device.

Solution: Check the plumbing, sprinkler and end discharge device, find out the leakage point and deal with the empty space.

6. The water flow indicator does not report the signal after the water flow action. Causes: In addition to the problems of electrical wiring and terminal crimping, the main problems are the water flow indicator itself, including the slurry does not move, the slurry is damaged, the micro switch is damaged or the reed switch contacts are burned, or the permanent magnet does not work.

Solution: Check whether the slurry is damaged or plugged, and check the permanent magnets, reed switches and other devices.

7. After the action of the nozzle or the end of the discharge device is opened, there is no water at the front end of the pipeline after the linkage pump. Reason: The butterfly valve of the wet alarm device does not work, and the wet alarm device cannot send water to the front pipeline.

Solution: Check the wet alarm device, mainly the butterfly valve, until it is flexibly flipped, and then check the other parts of the wet device.

8. The linkage signal is issued, and the spray pump does not operate. Cause: It may be a loose connection between the control device and the fire pump starting cabinet or a malfunction of the device, or it may be a mechanical failure of the sprinkler pump itself. Solution: Check the connections and the pump itself.

Hello has helped you to inquire: fire alarm line maintenance is as follows: date:

Fill in the contact**) Fault description: (Describe the fault situation in detail here, including the fault occurrence time, fault phenomenon, scope of influence and other information) Maintenance process: 1

Check the alarm controller and detector and find that the detector line is faulty. 2.A multimeter was used to test the line and found that there was an open circuit in the line.

3.Use maintenance tools to repair the open circuit and restore the smooth line. Wheel 4

Conduct a comprehensive inspection of the line wax or letter to confirm that there are no other faults. Maintenance result: After maintenance, the fire alarm line has been restored to normal operation and can be used normally.

There is no mandatory requirement to sign a maintenance contract. However, according to the relevant provisions of the regulations on the maintenance and management of building facilities: the general unit cannot meet the following requirements, and will not be equipped with relevant personnel, so it is necessary to ask a professional fire protection company to carry out maintenance operations.

Here are some of the regulations I've copied, and you can view them all online.

b) Technicians engaged in individual inspection and linkage inspection of building fire protection facilities shall pass the fire protection professional examination and take up their posts with certificates.

The professional and technical personnel and testing instruments and equipment of the unit equipped with the single inspection and linkage inspection of the construction of fire-fighting facilities can be in accordance with this standard.

Quasi-self-implementation, or can be entrusted with a unit with fire inspection intermediary service qualifications or with corresponding fire protection facilities installation qualifications.

Units shall be implemented in accordance with this standard.

c) The single inspection record of building fire protection facilities and the linkage inspection record of building fire protection facilities shall be signed and covered by the inspector and the testing unit.

Chapter. The inspectors and the testing unit shall issue the "Building Fire Protection Facilities Test and Inspection Record" and the "Building Fire Protection Facilities Linkage Inspection".

Records (see Appendix A) are responsible.

d) After the building fire protection facilities are put into use, they shall be guaranteed to be in normal operation or quasi-working condition, and shall not be cut off from power or long-term without authorization.

Work with faults.

e) Establish a registration system for failure reporting and fault elimination of building fire protection facilities. In the event of a malfunction, it shall be repaired in a timely manner. Due to malfunction

If it is necessary to temporarily suspend the system for maintenance and other reasons, it shall be approved by the person responsible for fire safety of the unit, and the system shall be out of service for more than 24 hours

At the same time as the approval of the person responsible for fire safety of the unit, it shall be reported to the local public security and fire department for the record, and effective measures shall be taken to ensure it.

The general unit cannot meet the above requirements, so it is necessary to ask a professional fire company to carry out maintenance operations.

He doesn't sign with you, I think it's because he wants to pay the bill if necessary.

Fire alarm system, also known as automatic fire alarm system, it is composed of trigger device, fire alarm device, linkage output device and other auxiliary function devices, it has the ability to burn in the early stage of the fire, the smoke, heat, flame and other physical quantities generated by combustion, through the fire detector into an electrical signal, transmitted to the fire alarm controller, and at the same time show the location of the fire, time, etc., so that people can find the fire in time, and take effective measures in time to extinguish the initial fire, Minimizing the loss of life and property caused by fire is a powerful tool for people to fight fire.

Fire alarm system is also known as fire alarm system, fire automatic alarm system.

It is composed of a fire alarm host, a fire feature or early fire feature sensor, an artificial fire alarm device, and an output control device.

The sensor completes the detection of fire characteristics or early fire characteristics and transmits the relevant signals to the fire alarm host.

The alarm host completes the display and recording of the signal, and completes the corresponding output control.

The automatic fire alarm system is an automatic fire-fighting facility set up in buildings or other places in order to detect and report the fire as early as possible, and take effective measures in time to control and extinguish the fire, and is a powerful tool for people to fight against the fire.

Well-known brands in the industry: Honeywell, Siemens, Yun'an (Shanghai Songjiang), Bay, Lida, Nengmei, Anshe, Oceanwide Sanjiang, Beida Jade Bird, Yiai.
