DESCRIPTION
The BLCD-20B works in conjunction with an auxiliary generator or central inverter system. The unit allows lighting
control devices for normal lighting to also control emergency lighting installed within the area. The BLCD-20B is
designed for lighting control in areas where emergency lighting fixtures are connected on dedicated emergency lighting circuits that are typically ON 24 hours per day. The BLCD-20B allows ON/OFF control of the emergency lighting
along with the normal room lighting to save energy. The intended operation of the BLCD-20B is to guarantee that
the emergency lighting is ON whenever normal power to the controlled circuit is interrupted. While normal power is
present, the BLCD-20B allows control of the emergency lighting by a device such as an occupancy sensor, a relay, a
dimmer, or a wall switch.
