10.9 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.
10.10 Firestat
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.
10.11 Hot Water Reheat
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.
