How to Properly Maintain and Care for Shielded Fire Alarm Cables

Shielded fire alarm cables are an essential part of any fire alarm system. They transmit signals from the fire alarm devices to the control panel, which then alerts the occupants of the building to a fire. It is important to properly maintain and care for shielded fire alarm cables to ensure that they are always in good working order.

Inspection and Testing

Regularly inspecting and testing shielded fire alarm cables is essential to ensure that they are in good condition. This should be done by a qualified electrician at least once a year. The inspection should include a visual examination of the cables for any damage, such as cuts, breaks, or corrosion. The electrician should also test the cables to ensure that they are conducting electricity properly.

Protection from Damage

Shielded fire alarm cables should be protected from damage. This includes protecting them from physical damage, such as being cut or crushed, as well as from environmental damage, such as exposure to moisture or extreme temperatures. Cables should be routed through conduit or other protective enclosures to prevent damage. They should also be kept away from sources of heat, such as furnaces or boilers.

Proper Installation

Shielded fire alarm cables must be properly installed to ensure that they are functioning properly. This includes using the correct type of cable for the application, as well as using the proper connectors and terminations. The cables should be installed in accordance with the manufacturer’s instructions.

Grounding

Shielded fire alarm cables must be properly grounded to ensure that they are protected from electrical interference. This involves connecting the shield of the cable to a ground rod or other suitable grounding point. The grounding should be done in accordance with the manufacturer’s instructions.

Maintenance Records

It is important to keep maintenance records for shielded fire alarm cables. These records should include the date of the inspection, the name of the inspector, and the results of the inspection. These records can be used to track the condition of the cables over time and to identify any potential problems.

By following these tips, you can help to ensure that your shielded fire alarm cables are always in good working order and that they will be able to protect your building in the event of a fire.
