WARNING
When the XNX is equipped with the optional Remote Mount Kit, the remote sensor MUST be securely
mounted to a xed position. The Remote Sensor Kit is not intended to be used as a hand-held
detector.
The XNX is configured with 5 cable/conduit entries built into the housing
for wiring and mounting sensors. Figure 3 provides the guidelines to proper
installation of the XNX.
NOTE
While relay wiring can use
any available cable/conduit
entry in the XNX enclosure,
do not use the same cable/
conduit entry for both relay
reset and relay signal lines to
avoid electrical noise.
