Abstract
A portable alarm system in which the alarm functions are contained within a portable enclosure, communication is maintained between the alarm system and wireless security devices, and the alarm is capable of initiating a telephone call to a S security monitoring station either by conventional hard-wired telephone lines within a building, by cellular transmission, or by 1900 megahertz PCS. The alarm is capable of initiating a call over the control channel of a cellular phone system. The latch key function allows a child to make his/her parents aware that he/she has arrived home safely.
Claims26
A portable alarm system, wherein said portable alarm system is adapted to send signals over a control channel of a cellular telephone system to a remote switching office, comprising:
