Do you need to know when an entry way, unauthorized areas, or exit is used? 

Entrance Alert Chimes have many different uses, such as home security, entrance notification, and motion detection. With a good entry alarm, you can easily monitor your business’ front door so you know when a customer enters with a pleasant and professional chime, or use as a motion detector alarm to warn of intrusion and deter theft.

How the product works:

The kit is comprised of three main pieces, 1 x a reflector, 1 x a sensor, and 1 x a speaker/chime.  The reflector and sensor are mounted on opposite ends of the entrance you would like to monitor.   When the invisible beam between the reflector and sensor is broken, the sensor sends a signal to the wired chime (connected to the sensor) and a “ding-dong” or alarm sound is emitted.  All components wire to each other, eliminating any need to hard-wiring.

Add-on counter and add-on speaker is available:

There are also add-on accessories available with theBALERT.  Users can connect an electronic counter (connects to plug on speaker) that will count sensor triggers.  Optionally, another speaker can be daisy-chained to the supplies speaker, extending the listening range of the product.  If the distance between the speakers exceeds 33 feet, an additional power adaptor is needed.  If an add-on speaker and add-on counter are added, an additional power supply is also needed.

The technology used in the Seco-LarmBALERTproduct has been around for decades and it is still relevant today because the simplicity makes it an easy setup and easier to use.  It’s reliable, relevant, and competitively priced.

    The beam alert works perfectly at my garage door opening. It was easy to install and must line up perfectly in order to work but no big deal there. Great product.
