ABSTRACT:
A security system comprises a control panel configured to control devices in a security system, a keypad and an arm/disarm device. The keypad is in communication with the control panel and comprises a transceiver configured to communicate with the control panel and a magnet having a magnetic field extending within a predetermined proximity of the keypad. The arm/disarm device comprises a transmitter and a switch configured to activate the transmitter when the switch is in the magnetic field. The transmitter is further configured to transmit a low power signal when activated. The transceiver is further configured to receive the low power signal and transmit a message to the control panel. The control panel is further configured to change an Armed/Disarmed Mode of the system based on the message.
