Smoke Detectors
Smoke detectors are available as factory--installed options on
RGH models. Smoke detectors may be specified for Supply
Air only without or with economizer. All components
necessary for operation are factory--provided and mounted.
The unit is factory--configured for immediate smoke detector
shutdown operation; additional wiring or modifications to
unit terminal board may be necessary to complete the unit
and smoke detector configuration to meet project
requirements.
Units equipped with factory--optional Return Air smoke
detectors require a relocation of the sensor module at unit
installation. See Fig. 35 for the as shipped location.

Smoke Detector assembly. See Fig. 36, Step 1. Save
