Fire protection

Most frequently used in smaller premises, the devices for a conventional alarm system are divided into zones: i.e. Zone 1 located on the 1st floor, and Zone 2 on the 2nd floor.

Each zone is connected to the control panel via its own radial circuit, but on activation it is not possible to pinpoint the exact location of the fire, only which Zone it is in.

It is a cost-effective system to buy and will meet the functional needs of small premises where a sophisticated system is not necessary.

An aspirating smoke detection system provides the earliest warning of an impending fire hazard due to the fact it can detect smoke before it is visible to the human eye. The system uses a fan to draw air in via a network of sampling pipes and holes.

The air is then analysed as it passes through a highly sensitive detector, which in turn generates a warning signal when appropriate.

One advantage of this system is the detection of cool smoke, which would not be picked up by a conventional system. Installation costs and routine maintenance are also beneficial.

Most industrial fires are undetected overheat conditions which have been allowed to progress to combustion. Linear Heat Detection Systems (LHD Systems) are designed to protect against pre-combustion overheat or early fire conditions without generating unwanted alarm signals.

Sensors in specially designed cable are able to detect abnormal temperature along its span, not just at specific locations.

LHD systems are easy to install and offer lower maintenance costs in all types of environments, including those that are inaccessible, such as tunnels, car parks, plant machinery (conveyor belts) and, or where fire detection needs to be close to the hazard.
