Smoke Detector

The smoke detector senses the return air, shuts down the unit upon detection, and sends visual and

audible alarm. Dry contacts are available for a remote customer alarm. This smoke detector is not

intended to function as or replace any room smoke detection system that may be required by local or

national codes.

Supervised smoke detectors are also available as an option. Consult factory.

The firestat senses return air temperature of the sys-

tem. Upon sensing high temperatures, the environmen-

tal control system is shut down. Required by codes in

certain areas.

Controlled by a two-way solenoid valve from the micro-

processor control panel, these economical reheats have

the capacity to maintain dry bulb conditions when the

system is calling for dehumidification. The system is

completely pre-piped and includes a control valve and

Y-strainer. The reheat coil is constructed of copper

tubes and aluminum fins.
