Patent ID: 7106193

Claim:
A security system peripheral device comprising a single housing suitable for mounting in a premises, said housing comprising: a) a primary alarm sensor adapted to monitor a primary protected area and to generate a primary alarm signal when said primary alarm sensor is triggered; b) an alarm verification unit adapted to selectively provide verification information from at least part of the primary protected area to a central station monitor; and c) processing circuitry adapted to (i) generate an alarm enable signal when said primary alarm signal is generated, and (ii) on the occurrence of an alarm enable signal, to: generate an alarm detected signal and cause the alarm detected signal to be transmitted to a central station monitor; and enable operation of the alarm verification unit; further comprising a secondary alarm sensor adapted to monitor a secondary protected area using an alarm sensing technology different than that of said primary alarm sensor and to generate a secondary alarm signal, said secondary protected area at least partially overlapping with said primary protected area, wherein said alarm enable signal is generated only on the occurrence of both the primary alarm signal and the secondary alarm signal.
