If you need a reliable entrance alert, especially for businesses or large retail stores, you may have realized that the products you get at the big box retail hardware stores like Home Depot, Lowes, or Ace Hardware simply won’t cut it.

That’s because they simply don’t have the power to produce the range needed to penetrate the environmental factors associated with commercial properties.  Steel, concrete, rebarb, etc., are all going to cut down on the range you need go the distance.

Most businesses purchase these products for safety reasons; to know when someone or something passes through a monitored zone, or for customer service reasons.  Some of our customers, for example, use these products to alert them when customers enter their store.  If a clerk is in the back working, the gentle chime sound notifies them of a customer entering their store, so they can immediately be available to greet them.

Convenience stores, gas stations and retailers use this product to notify them of customers entering the store and to notify them when customers are approaching unauthorized zones (like a back office).

The product ships as a kit with 1 x wireless PIR based transmitter and 1 x plug-in receiver.  The passive infrared sensor detects motion and heat which helps eliminate false alarms.  It is powered by 2 “AA” batteries and under normal usage should last 18-24 months.  It is important to note that cold weather will reduce battery life.

The transmitter mounts on the supplied mounting bracket with supplied mounting screws.  You can angle the transmitter on the mounting bracket to get the angle you need.  The sensor/transmitter is typically mounted over the area you would like to monitor.  The sensor produces a conical shape that fans out wider the further from the sensor you are.

The receiver plugs into a standard wall outlet, wherever you need to hear the chime. On back of the receiver is a volume control knob and at high setting is extremely loud.  If that is not loud enough you can wire a speaker to the live speaker terminal located on the back of the receiver.  The receiver also features a live 12V DC output that allows for integration with add-on devices like sirens, strobe lights, counters, buzzers, and more.

The receiver is capable of four zones meaning you can group as many sensors as you would like into a zone where each zone will play a distinct tone for notification.
