BLCD-20X2 Automatic Load Control Relay Maximum Lighting Load of 20A Universal Input APPLICATION The BLCD-20X2 works in conjunction with an auxiliary generator or central inverter system to power designated lighting loads up to 20 amps regardless of local switch position. The device consists of relay switching circuitry in a single, wall-mountable enclosure (T-bar mounting kit optional). The BLCD-20X2 senses the loss of normal power and, in response, switches the lighting load to a designated alternate power source. The device can be used to: (1) bypass a wall switch to allow generator- or central inverter system-supplied lighting loads to energize when normal power is lost; (2) bypass a dimming panel and prevent backfeed to allow lighting to energize at full brightness when normal power is lost; and (3) bypass most dimming controls using an auxiliary relay contact. The BLCD-20X2 includes three dry form C contacts, which allows the user a wide variety of wiring options. For additional applications and information, contact the factory. The BLCD-20X2 is suitable for use in indoor and damp locations.

OPERATION The BLCD-20X2 senses the loss of normal power and switches the lighting load, connecting it to a user designated standby circuit. No routine maintenance is required to keep the BLCD-20X2 functional; however, like other life safety unit equipment, it should be checked periodically to ensure that it is working properly.

INSTALLATION The BLCD-20X2 does not affect normal fixture operation and comes fully assembled for immediate installation. In addition to available wiring, the device requires a direct, unswitched connection to a normal power circuit and, depending on the application, an unswitched connection to a generator-supplied or central inverter system-supplied standby panel. See diagram A for typical installation.
