2.4.2Rear Access Alarms

To access the alarm outputs first ensure batteries are disconnected from the system by setting battery connection switch to “OFF” via controller front panel (see section 2.3) and by turning the external battery breaker off. The input mains supply must then be turned off by operating the local isolator or disconnection device. Remove the rear cover to leave the view as shown below. Labelled are the 3 signal output connectors SK14, SK17 and SK18 and also the temperature compensation connector SK19, where a thermistor is wired.

To use a particular alarm signal simply strip the ends of your alarm cables and enter into connectors by pushing down on respective lever, push in alarm cable and release lever to clamp cable. Cables should be routed through one of the knockout panels in the side of the shelf.
