What is Intelligent Fire Alarm System? Wiring Diagram


The intelligent fire alarm system is more efficient and advanced technology than the addressable fire alarm system. Nowadays intelligent fire alarm system comes with single standalone devices to large housing installation. This system also helps to find out the exact location of the detector or the accidental place.

This system provides a lot of features and advantages over other types of fire alarm systems. In this system also, all the detectors are connected in a loop wiring procedure. This system supports all types of detectors including multi-sensor detectors. The additional feature of this system is that it can support connecting multiple loops.

The detectors of an intelligent fire alarm system have their own programming device or mini computer. So, they not only send the signal when a fire happens, but they send another status also such as whether cleaning is required, moisture, internal faults, etc. In this fire alarm system, the fire alarm control panel can communicate with each detector individually. 

In this fire alarm system, a very large building or area can be monitored from a single control panel. An intelligent fire alarm system works with digital signals. Also, it allows connecting additional panels (repeater panel), computers, or other networks for remote control.

The intelligent fire alarm system is more complex than other systems. Its control panel records all the data from each loop and each detector separately. Also they are capable to store everything such as event history, scheduling, timing, etc. Also, it can help to check all the detectors individually whether they are functioning normally or not.

Intelligent Fire Alarm System Wiring and Connection Diagram


Here, you can see the wiring diagram of intelligent fire alarm system.

The control panel for the intelligent fire alarm system comes with 2 loops, 4 loops, and other multiple loop specifications. In the above diagram, a 2 loop system is shown. You can see, both loops have six detectors but it can be more. All the detectors have separate identification such as L1/D1 or L2/D2. Here, L1 means Loop 1 and D1 means detector 1. Similarly, L2 means loop 2, and D2 means detector 2. If the control panel shows an alarm regarding L1/D3. It means the accident happened near to the detector 3 in the loop 1.

Here you can see a repeater panel is connected to the main control panel. The repeater panel is the sub-panel that shows all the data of the control panel. Even they can control the whole system. The repeater panel that only shows the data same as the main control panel, but cannot control anything is called a passive repeater panel. On the other hand, the repeater panel shows data and can control the system is called an active repeater panel. The repeater panel is only connected to the main control panel. No initiating or notification devices are connected to the repeater panel.


Advantages of Intelligent Fire Alarm System


1. It shows the exact location of the fire-related accidental place.

2. It eliminates the chances of falls alarm.

3. It shows different environmental statuses and faults of the detector.

4. It is a flexible system and the response of each component is very fast.


Disadvantages of Intelligent Fire Alarm System


1. This system is more complex than other types of fire alarm systems.

2. Installation and maintenance cost is very high.
