General
Replacement end-of-line unit for use with the AlarmLine II Digital EN linear heat detection controller and AlarmLine II Digital EN linear heat detection cable.

Functional testing
Internally the unit features 4 switches, which can be used to simulate a fire or fault on each of the zones. There are two push-buttons, one for each zone, which simulate a fire by connecting the two cable cores when the button is pressed. Similarly there are two switches, which under normal conditions connect the end-of-line resistor across the cable, for each zone. However when the switch is changed, this create an open circuit which in turn raises a fault on the controller. Via these switches it is easy to functionally test the system.
