Types of Fire Alarm System:
We have seen the various types of fire detectors. Now we will see the classification of the Fire Alarm System. These are given below:
- Convention Fire Alarm System
- Intelligent Fire Alarm System
- Wireless Fire Alarm System
Convention Fire Alarm System:
The name of this fire alarm system is self-explanatory. In this system, wired cabling is used to connect call points, detectors, and central control units. Detected signals are being carried by wired to control unit. Call points and detectors are arranged in zones. This zoning technique simplifies locating the cause of the alarm in a specific one. Everyone appears in the central control panel either with an indicator light or on a display screen. In a conventional fire alarm system, the control panel is wired to at least two alarm circuits.
Intelligent Fire Alarm System:
In the next type of system, each detector effectively incorporates its intelligence which evaluates the environment around it and communicates to the central control panel whether there is a fire, fault or the detectors need cleaning. This is the intelligent fire alarm system. As this system has more intelligence as compared to other fire alarm systems so it also has more complexity. The main feature of this system is to avoid false alarms.
Wireless Fire Alarm System:
Now, we will see a wireless fire alarm system. These systems are an effective alternative to conventional fire alarm systems. This wireless system utilizes secure, radio communication-based interconnected sensors and devices with the controllers. In this system, every detector has its wireless connectivity with a wireless communicator. When detectors sense fire or smoke then they send a trigger signal to the wireless communicator. This communicator received these trigger signals and sends them to the central control unit of the fire alarm system. That’s how it works.
