Electronic Assembly consist of one top transmitter board (connected to the cover plate) and on lower 
interface board.   Connectors for wiring for power, signal interface and alarm relays are located on the 
interface board assembly 

The sensor assembly includes an explosion proof housing containing the gas sensor and a wiring harness 
for connection to the transmitter.  The sensor assembly threads into one hub of the enclosure.  The 
exposed end of the sensor assembly is threaded to allow connection of a rain-shield or calibration gas 
delivery fitting. 

Not supplied with the sensor module, but necessary to the installation and operation is the multi conductor 
wiring which connects the module to its power source and controller.  Before this wiring is installed it is 
important to read and understand the control system installation instructions to determine wiring requirements 
and alternatives.   

 modules operate on DC power between 10 VDC and 30 VDC.  Regulated DC power must be supplied from 

a separate source, or from an approved Sentry or 

 controller.
