S Detector Component Location
The sensor is secured within the sensor housing by four pins. Through a series of chemical and
electrical reactions, the sensor produces an electrical output that corresponds to the detection range
of the detector. A pre-amplifier, located between the sockets and two interconnect wires, conditions
the sensor’s signal before the signal reaches the controller. A rubber boot and spacer are installed
on the sensor face to ensure that the sensor remains plugged into the detector housing body.
12 VDC Battery Cable
A 50 foot cable with clamps for connection to a 12 VDC battery (customer supplied battery not
included) is factory-wired through the left cable bushing of the Beacon 110. One end of the cable is
connected to the Beacon 110 terminal strips.
