How does it work?
The SKM heat sensing cable system provides early warning of an impending fire by detecting overheating in cable ducts, road tunnels, escalators, lift shafts, conveyor belts and similar difficult to monitor environments. The system uses 'Firesense' analogue heat sensing cable and the SKM-03 or SKM-95 controllers plus an end of line terminal box. The sensor cable is specially contructed coaxial cable. When the cable is heated there is a corresponding change in the electrical characteristics of the cable. This change is monitored by the controller and when sufficient causes an alarm. The controller constantly monitors for open and short circuit faults in the cable. Firesense cable may be physically heat tested any number of times, however, if it is destroyed by overheating or fire, the damaged section must be replaced.
