Abstract: In an integrated system of alarm components used in the real estate industry, the product family consists of three primary components: a portable transmitter unit, a vehicle-mounted transceiver unit, and a house-installed receiver unit. The system is intended to enhance the personal safety of real estate professionals who venture into the field, e.g., to show vacant houses to potential buyers. The transmitter is sized to be handheld, attached with a belt clip, or carried in pocket. When a panic button on the transmitter is depressed, the transmitter sends coded radio frequency signals which will activate either or both of the vehicle-mounted transceiver and the house-installed receiver as well as other system devices within range. When the transceiver is activated, the unit's horn will sound, and the transceiver will in turn transmit a coded radio frequency signal to any one or more identified receiver units sharing the same signal code.
