Description

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.

  • SL-40 uses a passive-infrared sensor that is triggered with a combination of heat and movement.  This helps eliminate false alarms caused by shadows, leaves, etc.
  • The product emits a chime sound when triggered
  • A volume control allows you to adjust the volume to your specifications
  • Mounting the product is easy, using the supplied mounting bracket
  • Angle the product to monitor your desired area
  • No wiring required
  • Powered by a 9-volt battery. Under normal conditions, battery should last 18-24 months prior to replacement.
  • Product is made in America

Great, basic doorbell

We've purchased 20+ of these doorbells for the entrances of all of our convenience stores. They're simple to install and serve their purpose well for a basic motion alert when the door opens.
