RAILED SYSTEM

The mobile unit ‚S' is installed on a mono rail system and carries a water reservoir of 2,000 litres with sufficient air supply. The unit is fully self-contained with battery driven electrical motors, batteries, braking mechanism and magnetic lock. The unit can move at a speed of 20 to 40 km/h; the units will be installed at every 1,500 metres and so will be on the site of the fire under 3 minutes.

In a fire situation, the alarm signal is transmitted automatically to the IFEX unit and causes it to start driving to the section on fire. The unit is provided with an infrared detector and a monitoring system that pans and tilts the cannons into the right direction and shoots automatically right into the base of the fire. 		  

The mobile unit ‚L' is basically the same system as the unit ‚S', but is installed on a dual rail system and therefore is able to carry a water reservoir of 3,500 litres.


FIXED SYSTEM

The IFEX fixed system application for road and train tunnels consist of high performance impulse cannons with capacities of 12 to 40 litres per impulse shot. Every 60 metres, a unit is mounted into the tunnel wall consisting of two impulse cannons shooting in both directions to totally cover the section. The cannons are tilted downwards for maximum efficiency and overlapping.

The fire detection system detects the fire by means of flame and rate of heat release detectors. In a fire situation, the cannons within the section and the cannons located on each side of the section are activated.
