The feature-packed unit also provides outputs for traffic lights, door violation alarms, and provides three individual timing sequences for propped door time, emergency override unlock, and request-to-exit unlock time.

For added installation versatility, the 48900 Series PLC interlock Controller can be paired with a 4-, 6-, or 10-Amp UL 294 power supply that includes a Fire Alarm connection for emergency egress and can provide power to operate maglocks, electric strikes, and traffic lights. The controller is also available without the power supply and enclosure for connection to an existing 12-24VDC power source.
