Conveyor belt fire detectionAlarmline sensor cable installed directly at the support roller bearings location. This is to monitor what has been independently proven to be the greatest risk- an overheated condition generated by friction igniting the build up of material spilled from the belt. A wide range of clips and fastenings are available to match the environment and installation method.
Alarmline sensor cable can be installed directly over the conveyor to detect a fire/overheat on a stationary conveyor.
Bronze braided sensor cable is recommended as this provides greater protection against possible mechanical damage.
The Alarmline sensor cable should be run down both sides of the conveyor belt To give greater protection against build up of material under the bed of the conveyor Alarmline can be installed under the conveyor as shown in figure
