Doorway Beam Sensor Alarm or Chime

Product Description:

The Doorway Beam Sensor is designed to sound a user selectable chime or alarm when someone walks through the invisible beam of infrared light. A focused infrared (IR) light beam is projected from an emitter and bounced off of a reflector which is placed at the other side of the detection area. A sensor built into the emitter detects when the infrared beam is broken by the passing of a person or the presence of an object in the path of the infrared beam. A separate speaker annunciator (included) can be set to chime or alarm to alert you that a security breech has occurred or that an object has entered or passed through the infrared beam.

Possible uses include:

• Access control - entry detection: E.G.: Notifying store operators that a customer has entered the store
• Home or commercial security system
• Manufacturing process control "presence" detection of objects
