Application
LCH and LGH Units −− Smoke detector will send a 24Vac
signal to the unit controller when smoke is sensed. The unit
controller default mode will de−energize unit.
KC/KG/KH Units −−Smoke detector will interrupt the
24Vac signal to the unit control circuit when smoke is
sensed. Unit will be de−energized.
Kit 83W40 (603408−07) is used in either supply or return
air applications. Kit 83W41 (603408−08) is used when
both supply and return air smoke detectors are installed.
