CAUTION
Danger of sharp metallic edges. Can cause injury.
Take care when servicing unit to avoid accidental
contact with sharp edges.
Application
LC and LG 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 and KH Units -- Smoke detector will interrupt the
24Vac signal to the unit control circuit when smoke is
sensed. Unit will be de-energized.
