Monitor a driveway or any entrance with the Seco-Larm Enforcer Wireless Door Entry Alert With Chime. The weatherproof photoelectric beam sensor installs indoor or outdoors directly across from the reflector. When the beam between the sensor and reflector is broken, the sensor triggers the door entry chime's alert through the wireless speaker. The door entry chime's speaker can be placed up to 328 feet away, so you can receive alerts wherever you need them.
The wireless door entry alert's speaker can be set up to make either a "ding dong" or siren sound when triggered by the sensor. When in siren mode, sounding time is adjustable from 3-30 seconds. The speaker’s volume can also be adjusted
