As the personal communications market grows worldwide, new ideas are evolving to enhance the use of products. One such idea is the use of a per- sonal communication device, like a CT2 handset and private base station, to be used in conjunction with a security alarm, to form a state of the art securitty system.
This invention consists of a simplified private base station circuitry (no telephone line circuitry) and modified software. It would connect to an existing alarm circuitry and perform the function of arming and disarming the alarm via the location of the CT2 handset unit(s) registered to it. It would also communicate an activated alarm situation when the alarm is tripped. The following describes the functions in more detail:
set is found in the proximity area. In the disarm state, the homebase would initiate communication periodically looking for 'no response' to start the arm cycle once again,
ACTIVATED ALARM COMMUNICATION
Once the alarm is tripped, the homebase circuit would sense this condition and immediately initi- ate communication, in high power mode (for maxi- mum range), with registered handsets. This would continue until the alarm circuit times out or is pow- ered down.
CONNECTIONS
ARM/DISARM
When the alarm circuit is powered on, the arming and disarming of the alarm is performed by sensing the proximity of the CT2 handset(s) regis- tered to it. The private base station circuit would send out a signal, in a power cu...
