Fire alarm systems are essential in the protection of lives and properties against fire hazards. A properly installed and maintained fire alarm system can greatly reduce the risk of serious damage caused by fires. It is designed to detect smoke, heat, or fire and notify the occupants of potential danger through audible and visual alarms. In this guide, we will discuss how to wire fire alarm system properly.
Necessary Items
Before starting the wiring process, it is necessary to gather all the required items. These include:
- Fire alarm control panel (FACP)
- Smoke detectors
- Heat detectors
- Pull stations
- Horn strobes or bells
- Conduit and wire for connections
Make sure to purchase these items from a reputable supplier and check their compatibility with each other.
Why Use a Fire Alarm System?
A fire alarm system is crucial for the safety of the building’s occupants and immediate response to a fire. It provides early detection, which can prevent serious damage or loss of life. Additionally, it can also help in notifying emergency services for prompt action.
Also, in some countries, a functional fire alarm system is required by law for certain types of buildings. There are two main types of fire alarm systems: conventional and addressable. Conventional fire alarm systems have zones that cover specific areas of the building.
When a detector within a zone detects smoke or heat, the corresponding zone will be identified on the control panel. On the other hand, addressable fire alarm systems have individual addresses for each detector, allowing for more precise identification of the location of the fire.
