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/dental style offices with a receptionist who is at the front desk the whole time. 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.
