The ENFORCER wireless entry alert system is on the market.
Its reflective photoelectric beam sensor, when tripped, wirelessly communicates with a speak located up to 328 ft / 100 m away. An additional speaker may be installed to alert more than one area. An optional solar charger is also available to install with the sensor for additional convenience.
The ENFORCER's weatherproof sensor offers a range to 22 ft for use as an entrance indicator. There is no wiring between the speaker and sensor.
In alarm mode, system sounding time adjusts from 1 to 30 sec. Three entry alert models are offered on which you may request free information.
