More on Fire Detection

Conventional fire detection systems are the simplest form of systems utilising a control panel and field devices, including smoke and heat detectors and manual call points. These systems are wired in zones with the field devices decreasing the zone resistance when activated with the fire alarm control panel detecting this change of resistance.

The information generated by the control panel of a conventional fire detection system is limited to indication of which zone has activated only. This could be anyone of a number of individual field devices. This is the main restriction of this type of system as the search time to discover which device has activated is much longer and therefore restricts these systems to smaller less complicated buildings and applications.

With our knowledge and experience at ADC Fire Systems Ltd we can advice as to whether this type of system is suitable for your application and requirements.

Gas Suppression

Gas suppression systems are a valuable tool for containing a fire and preventing combustion. The fire is stopped from re-ignition until human intervention can permanently stop the fire with minimal level of damage to valuable equipment and stored items.

Water is an excellent extinguishing agent but can cause a great deal of damage to buildings and items within these buildings when used to extinguish fires.

The principle of Gas Suppression involves reducing the level of oxygen within a set area by increasing the level of other gasses. This reduction in oxygen stops the re-ignition of a fire allowing it to be contained. There are a variety of gasses that can be used but each individual application needs to be assessed for risk to life, equipment and valuable objects to determine the most effective type.

Similarly to Air sampling / aspiration systems the application for this technology is normally parts of buildings which are regarded as business critical or areas where items of high value are stored. This includes galleries, server rooms and data centres.
