Is this unit right for me?

This unit uses passive infrared detection which detects heat and motion, and chimes right at the door. While it does have a volume control knob inside the unit, it is intended to be used in small, boutique-style shops or medical type offices with a receptionist who continuously sits at the front desk during office hours. The SL-40 is not customizable. It is a stand-alone unit and as such, may not have any accessories such as buzzers or speakers added to it. It also does not work with an RX1000A or RX2000A receiver. If you have an RX receiver and are looking for a wireless sensor to work with it, please look at the TX1000A or TX2000A.

The SL-40 is made in the USA, and comes with a 30-day money back guarantee, and a one-year warranty.
