S detector is factory wired through the right cable bushing of the Beacon 110 controller and
has a 25 foot cable for remote installation. The mounting bracket at the top of the junction box is
used to mount the junction box. The junction box protects the detector wiring connections. Three
spacers installed on the back of the junction box control the distance of the junction box from a
mounting surface and ensure that there is enough room to perform a calibration. A cover on the
front of the junction box allows access to the interior of the junction box.
The detector housing body protects the sensing components within the housing. Use the removable
cap near the bottom of the housing to access the sensor for maintenance or replacement. The cap
protects the sensor from damage and includes a flame arrestor which contains any sparks which
may occur within the detector housing. A cap gasket seals the interface between the housing and
cap. A flame arrestor guard is permanently bonded to the cap.
The calibration cup/splash guard is screwed onto the bottom of the flame arrestor guard.
