NAPCO GEM-TRANS 2 Magnetic reed-switch system detects intrusion

Use these Wireless Window/Door Transmitters to protect anything that opens and closes, including doors, windows, jewelry cases, gun cabinets and more! These sensors use a magnetic reed-switch system to detect intrusion. When the magnet is separated from the sensor (when armed), the transmitter immediately sends a wireless alarm signal to the system's control panel. These compact, low-profile sensors install in minutes! Just mount them along the door or window frame. Each transmitter requires a 3V lithium battery (included).
