LEL Detector Junction Box and Cable
The LEL detector consists of a junction box with a mounting bracket, the
detector, and the calibration cup/splash guard.
The LEL detector is factory wired through the left cable bushing of the
Beacon 200 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
