Be alerted when a door or window in your home is opened with this Door/Window transmitter from Silent Call. When the door or window is opened, you are alerted through any 318MHz Silent Call receiver (sold separately).
This unit consists of two small magnetic contact bars and a transmitter. When the door or window is opened, the two bars lose magnetic contact, triggering the transmitter. The transmitter then sends a signal to any 318MHz Silent Call receiver (required - sold separately). Easy to install; adhesive strips are included. Operates on 2 AAA batteries. Range of up to 500 feet depending on receiver.
What else do I need to make this work?
In order to be notified, you will need to purchase a receiver that lets you know when the signaler or transmitter is activated.
