The EWP-202C is a two channel wireless annunciator system designed with a superior dual counter and active infrared technology. It delivers a pleasant chime along with a recorded count. It emits a continuous, invisible dual beam across the doorway to the reflector. When either beam is interrupted, it announces the entrance or exit of customers with a pleasant, distinguishable chime sound. Each event is counted, recorded, and registered by the built-in digital counter and can be viewed and compared later in both modes. The annunciator is also equipped with an alert mode that sounds the built-in siren when triggered, adding additional security. This is ideal for malls, office buildings, liquor stores, warehouses, parking structures, medical offices, and more.
