1.5.2 Transmitter Electronics

Electronic Assembly consisting of one printed circuit board assembly mounted under a cover plate, plugged into one field
termination board. Connectors for wiring for power, signal interface and alarm relays are located on the bottom of the
termination board.

1.5.3 Sensor Assembly

The sensor assembly includes an Aluminum or Stainless Steel 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.

1.6

Interconnect Wiring

Not supplied with the sensor module, but necessary to the installation and operation is the shield cable 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.

1.7

Power Requirements

The modules operate on 24 VDC power between 10 VDC and 30 VDC. Filtered, regulated DC power must be supplied from
a separate source or from an approved Sentry or IT controller.
