Types and Working Principle of Intelligent Fire Alarm System

An intelligent fire alarm system is a system that assesses the environment around the system and sends a signal to the control panel about the possibility of fault, fire, or need for cleaning of detector head.

Generally, intelligent systems are more complex than addressable and conventional systems. The main aim of this system is to prevent the occurrence of any false alarms.

To get the best offer, it is important to source this system from a reputable manufacturer who is a major dealer in the industry. It will help you to avoid imitation products.

Working Principles of Intelligent Fire Alarm System

The system is designed to quickly check any possible outbreak of fire. It is available in 2, 4, and 8 loop forms. Invariably, you can monitor large premises using a single panel.

There is looping of the wire and connection of the wire to the control panel at each point. All detectors, sounders, call points, and interface modules are joined to the loop. Each of the loops has an address of its own.

The function of the control panel is to communicate with each of the loops. When a fault condition or alarm detects a fire, it triggers the exact detector.

The loop is powered at each end. If the loop breaks at any place, there is no loss of devices. Furthermore, circuit isolators in the system reduce the area of coverage lost when there is short-circuiting.

Types of Intelligent Alarm System

There are two main types of intelligent alarm systems. They are:

  • Analogue intelligent alarm system
  • Addressable intelligent alarm system

1. Analogue Intelligent Alarm System

In the analogue system, the sensor or detector brings back a value to the control panel. The value represents the present state of the sensing elements. The control panel checks the value and compares it with the threshold of the alarm.

The comparison helps it to know whether there is a fire or not. The term analogue here refers to the nature of the response of the variable from the detector to the panel. It does not refer to the method of communication.

2. Addressable Intelligent Alarm System

In this system, the design is programmed to detect each device by the panel. The detector compares the value of the current sensor with the programmed threshold to a decision. The decision is then communicated to the control panel when there is an interrogation of the sensor.

In most systems, the offered features by both detection methods are quite similar to the point that it is not relevant which method is used to make alarm decisions. The best thing to do is to choose a system the system offers.

Communication Protocol

It is essential to know that intelligent alarm systems use similar pairs of wires to communicate with devices and supply power to the loop. The communication protocol varies from producer to producer.
