  • Two wire alarm
    Patent number: 7199722
    Abstract: An alarm device that connects to a circuit using two wires and is actuated when a switch changes the status of the circuit from a normally closed circuit condition to open circuit condition. The alarm device includes a PC board with an electronic buzzer, an electronic signal transmitter and/or a visual indicator, such as a flashing LED, all of which may be enclosed within a case. The circuitry of the alarm device is non-polarized, thereby allowing the two wires to be connected to either terminal connection point in the circuit.
