Door and window transmitters are probably the most important accessories when it comes to a home alarm system. They are the first line of defense at every entry point in your home. If your home has a uniformed style to it, a protruding door/window contact is the last thing you want. So how do you maintain a well-tempered home decor and get the security and protection you need to sleep peacefully at night?

Slim, compact and attractive, the WS4945BN - DSC Wireless Door/Window Transmitter is stealthy and blends right in with the decor of any home or business. This model comes in brown to match darker walls, base boards, doors and windows.

It will work as a self-contained magnetic door or window contact complete with a surface mount magnet and fully supervised by a controller. Like most contacts, it features a built-in reed switch for high functionality. Operating temperature is 32deg.F to 122deg.F and 0deg.C to 50deg.C and the transmitter will keep you aware of low battery, device fault. It holds an open/close 3 year battery life with a lithium battery (supplied) and alerts in defensive of its case or wall tamper.

Every door and window in a home or office should have an Alarm Contacts installed on it. You should always remember to include openings in the overall count. Depending upon a home’s or business size, this may end up being a lot of contacts, but it is important to avoid skipping a single door or window since each serves as a potential entry point for a burglar.
