Fire Alarm System

Fire alarm systems have become increasingly sophisticated and functionally more capable and reliable in recent years. They are designed to fulfill two general requirements: protection of property and assets and protection of life. As a result of state and local codes, the life-safety aspect of fire protection has become a major factor in the last two decades.

Fire Alarm Systems essentially operate on the principle where a detector detects smoke or heat, or someone operates a break glass unit, then alarm sounders operate to warn others in the building that there may be a fire and to evacuate. It is additionally likely that the Fire Alarm will incorporate remote signaling equipment which would alert the fire brigade via a central station.

A fire alarm system comprises a central Control and Indicating Equipment (CIE) with various types of detectors, manual call points (MCP), interface units and sounders connected to it.

Wired Fire Alarm Systems can be broken down into two categories

Conventional Panel: 2 Zone to multi Zone Panels

Addressable Panel: 1 Loop to multiloop panels

Touch screen Panels, Networkable, Bacnet /Modbus Compatible

Types of Detector & Devices

SMOKE/HEAT/MULTISENSOR

VESDA (Very Early Smoke Detection Apparatus)

VESDA: (Very Early Smoke Detection Apparatus) is a very early warning aspirating smoke detection solution. With continuous air sampling, it provides the earliest possible warning of an impending fire hazard. VESDA aspirating smoke detectors buy the critical time needed to investigate an alarm and initiate an appropriate response to prevent injury, property damage or business disruption.

Applications

Warehouse
Cold rooms
Computer rooms

Fire suppression Environments
Ceiling Voids
Lift shats and other critical locations

Linear Heat detection Cable

Linear Heat detection Cable is a very commonly used method of fire detection to detect a fire anywhere along the length of a cable. Linear Heat Detection (LHD) cable is essentially a two-core cable terminated by an end-of-line resistor(resistance varies with application). The two cores are separated by a polymer plastic, that is designed to melt at a specific temperature which causes the two cores to short. This can be seen as a change in resistance in the wire and sends a signal to the controller.
