3.5.6 Remote Mounting Applications
Some sensor mounting applications require that the gas sensor head be remotely mounted away from the sensor
transmitter. This is usually true in instances where the gas sensor head must be mounted in a location that is diff i-
cult to access. Such a location creates problems for maintenance and calibration activities. Detcon provides the IR-
640/IR-642 sensor in a remote-mount conf iguration in which the sensor (Model IR-640-RS) and the transmitter
(Model IR-640-RT) are provided in their own condulet housing and are interfaced together with a six conductor
cable. Shielded cable is required and must be installed in its own (unshared) conduit (use Alpha Wire Company
#6342 cable). A maximum of 100 feet of separation is allowed. Reference f igure 5A for wiring diagram.

Upon completion of all mechanical mounting and termination of all f ield wiring, apply system power and observe
the following normal conditions:
a)
IR-640/IR-642 “Fault” LED is off.
b)
A reading of 0.00% CO2 should be indicated upon conclusion of a 12 second “warming up” cycle.
NOTE: All alarms will be disabled for 1 minute after power up. In the event of power failure, the alarm disable peri-
od will begin again once power has been restored.
