SMOKE DETECTORS
Smoke detectors are available as factory-installed options on
50FC models. Smoke detectors may be specified for supply air
only, for return air without or with economizer, or in combination
of supply air and return air. 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. 52 for the as-shipped location.
