Door Annunciator System

The EBP-407C annunciator system is designed with a superior dual-counter, dual-active, infrared technology. The invisible infrared beam is designed to trigger a pleasant chime sound. The infrared signal differentiates among entry and exit. The dual entry/exit counter registers a count any time the beams are interrupted. Each event is counted, recorded, and registered by the built-in digital counter, and can be viewed and compared later in entry/exit modes.
