The ANN-20L is a 20 L.E.D. annunciator panel. The standard unit is built in three gang size but any sizes and lamp capacities are available. A 24 pin ribbon cable (1 per 20 lamps) is provided for easy installation and removal of the device.

This panel is equipped with our EC-2 self repeating electronic chime unit. The chime operates on 24 volts A.C. or D.C. Upon receiving power the chime will sound for approximately one full second. If power is held to the unit for more than ten seconds the chime will sound again. If a pulsating voltage is applied the chime will sound on each pulse.

As these panels are custom built, any specifications you require are possible (lamp colors, operating voltage, size, capacity). We will provide prompt quotations on all special units.
