A Reliable Entrance Alert that Installs in Minutes!
The product is simple in nature. Simply mount it above the area you want to monitor, like an entrance or a doorway. When a visitor passes through the monitored zone, the passive-infrared sensor is triggered. When this happens, a chime sound eminates from the sensor. With an adjustable volume control, you can adjust the sound to the level necessary.
The product is ideal for mid-sized offices, shops and stores measuring up to 2,500-3,000 square feet.
If you want the chime to sound at a remote location, please see the Rodann Wireless DA-50L-A.
The SL-40 is an all-in-one motion detecting unit. When its infrared sensor detects motion, a gentle alarm is triggered. Because it uses infrared technology, the SL-40 is resistant to false alarms – no need to worry about sunlight or reflections setting it off. It will also work when the door is open or closed, making this a reliable product that meets a variety of demands.
