Fire Alarm System Device Inspection and Maintenance

Linear beam smoke detector

Inspection requirements:

1. Check whether the linear beam smoke detector works properly every quarter.

2. There should be 10% spare parts for linear beam smoke detectors.

Maintenance:

1. Re-tighten the loosely connected terminals of the equipment, replace the wiring parts such as screws with rust marks, terminal gaskets, etc., remove the rusted wire ends, and reconnect after tinning.

2. Clean the optical window with special cleaning tools or soft cloth and appropriate detergent every quarter. After cleaning, calibrate the detector response threshold to the threshold set by the factory.

3. Necessary functional tests should be done after the linear beam smoke detector is cleaned, and it can continue to be used only after passing the test.

Aspirating smoke detector

Inspection requirements:

1. Check whether the working status of the aspirating smoke detector is normal every quarter.

2. Check the event record of the aspirating smoke detector every quarter to understand the situation of the protected area.

3. Check the status and usage of the filter of the aspirating smoke detector every quarter, and judge whether the filter needs to be replaced.

4. Check the airflow value displayed on the aspirating smoke detector quarterly. Judging the blockage of the sampling pipeline and dealing with the problem in time.

5. Check the sampling pipeline every six months for blockage, rupture, loose fixation, etc., and deal with problems in time.

Maintenance:

1. Re-tighten the loosely connected terminals of the equipment, replace the wiring parts such as screws with rust marks, terminal gaskets, etc., remove the rusted wire ends, and reconnect after tinning.

2. For the aspirating smoke detectors that sample through the sampling pipe, flush the sampling pipe at least once a year, replace the filter once a year, and conduct an alarm function test.

3. Maintain according to the equipment product manual.

Point-type flame detector

Inspection requirements:

Check whether the point-type flame detector works normally or not every quarter.

Maintenance:

1. Re-tighten the loosely connected terminals of the equipment, replace the wiring parts such as screws with rust marks, terminal gaskets, etc., remove the rusted wire ends, and reconnect after tinning.

2. Maintain according to the product manual.

3. Use special cleaning tools or soft cloth and appropriate detergent to clean the optical window.

Manual call point

Inspection requirements:

1. Check every quarter whether the working status of the manual call point is normal.

2. Check the functions of the button alarm contacts of the manual call point and the mechanical alarm parts every quarter.

Maintenance:

1. Re-tighten the equipment, connect loose terminals, replace wiring components such as screws with rust marks, terminal gaskets, etc., remove the rusted wire ends, and reconnect after tinning.

2. Solve the component fault problems to ensure the operation and normal functions of the device.

Strobe sounder

Inspection requirements:

Check if the strobe sounder works normally every quarter.

Maintenance:

1. Re-tighten the loosely connected terminals of the equipment, replace the wiring components such as screws with rust marks, terminal gaskets, etc., remove the rusted wire ends, and reconnect after tinning.
