Abstract

An action control process of a security alarm system is to render the general security alarm system to contain an auxiliary function of monitoring or detecting human activity within the monitoring area of the security alarm system, by utilizing the plurality of selected security devices selected from the security devices of the security alarm system during both armed or disarmed condition, without scarifying the original alarm protection functions. The action control process includes the steps of maintaining the plurality of selected security devices of the security alarm system in functioning condition when the security alarm system is set to a standby condition; computing a predetermined period of monitoring time; detecting any motion activity occurred inside at least a monitoring area by the selected security devices installed in the monitoring area during the predetermined period of monitoring time; resetting to compute the predetermined period of monitoring time initially again when a motion activity is detected by one of the selected security devices installed in the monitoring area within the predetermined period of monitoring time; detecting no motion activity in the monitoring area by any of the selected security devices after the predetermined period of monitoring time; and activating at least an alert device to perform an alert response.

Claims

1. An action control process of a security alarm system comprising a control system, a plurality of security devices connected to said control system providing with at least an alert device, wherein said action control process comprises the steps of:

(a) maintaining a plurality of selected security devices selected from said security devices of said security alarm system in functioning condition;

(b) computing a predetermined period of monitoring time;

(c) detecting any motion activity occurred inside at least a monitoring area by said selected security devices installed in the monitoring area during said predetermined period of monitoring time;

(d) resetting to compute said predetermined period of monitoring time initially again when a motion activity is detected by one of said selected security devices installed in said monitoring area within said predetermined period of monitoring time;

(e) detecting no motion activity in said monitoring area by any of said selected security devices after said predetermined period of monitoring time; and

(f) activating said alert device to perform an alert response.

2. The action control process, as recited in claim 1, wherein said selected security devices include a plurality of motion and activity sensors.

3. The action control process, as recited in claim 2, wherein said security devices include opening contacts for doors and windows, carpet mat sensors, electric door switches, and microphones for sound detection, passive infrared detectors, microwave detectors, ultrasonic detectors, laser beam detectors, and photo beam sensors.

4. The action control process, as recited in claim 1, wherein said action control process is processed during a disarming condition of said security alarm system when said security alarm system is switched off.

5. The action control process, as recited in claim 4, wherein said action control process is also processed during a partial arming condition of said security alarm system, wherein said security alarm system is switched on by an user to activate all said security devices to function but said user does not leave by opening and closing an entrance/exit door within a certain period of preset time.

6. The action control process, as recited in claim 1, further comprising a step of stopping the computing of said predetermined period of monitoring time automatically upon said security alarm system is set to a fully arming condition.

7. The action control process, as recited in claim 2, further comprising a step of stopping the computing of said predetermined period of monitoring time automatically upon said security alarm system is set to a fully arming condition.

8. The action control process, as recited in claim 3, further comprising a step of stopping the computing of said predetermined period of monitoring time automatically upon said security alarm system is set to a fully arming condition.

9. The action control process, as recited in claim 4, further comprising a step of stopping the computing of said predetermined period of monitoring time automatically upon said security alarm system is set to a fully arming condition.

10. The action control process, as recited in claim 5, further comprising a step of stopping the computing of said predetermined period of monitoring time automatically upon said security alarm system is set to a fully arming condition.

11. The action control process, as recited in claim 1, wherein said alert device includes a communication device for dialing phone call to predetermined location and an alarm control for triggering a local audible and visual warning protection device.

12. The action control process, as recited in claim 5, wherein said alert device includes a communication device for dialing phone call to predetermined location and an alarm control for triggering a local audible and visual warning protection device.

13. The action control process, as recited in claim 10, wherein said alert device includes a communication device for dialing phone call to predetermined location and an alarm control for triggering a local audible and visual warning protection device.

14. An action control device electrically connected between a plurality of selected security devices selecting from all security devices of a security alarm system and a control system of said security alarm system which provides at least an alert device, wherein said action control device comprises:

a time selector which is a time setting circuit for presetting a predetermined period of monitoring time;

a control processor unit, which comprises a timer counter and a processor, for picking signal from each of said selected security devices and processing the steps of

computing said predetermined period of monitoring time preset in said time selector;

detecting any motion activity occurred inside at least a monitoring area by said selected security devices installed in said monitoring area during said predetermined period of monitoring time;

resetting to compute said predetermined period of monitoring time initially again when a motion activity is detected by one of said selected security devices installed in said monitoring area within said predetermined period of monitoring time;

detecting no motion activity in said monitoring area by any of said selected security devices after said predetermined period of monitoring time; and

activating said alert device to perform an alert response;

a device input circuit for electrically connecting said selected security devices to said central processor unit for ensuring signals input to said central processor unit is readable and compatible with said central processor unit; and

an output circuit for electrically connecting said central processor unit to said alert device for outputting action control response to said control system.

15. The action control device, as recited in claim 14, further comprising a local control independently connected to said central processor unit via a relay output circuit for producing action control response.

16. The action control device, as recited in claim 14, further comprising a status control circuit for indicating whether said security alarm system is fully arming condition, partial arming condition or disarming condition and whether said action control device is normally functioned or disabled.

17. The action control device, as recited in claim 15, further comprising a status control circuit for indicating whether said security alarm system is fully arming condition, partial arming condition or disarming condition and whether said action control device is normally functioned or disabled.

18. The action control device, as recited in claim 14, wherein said predetermined period of monitoring time is selected from 1 hour to 99 hours.

19. The action control device, as recited in claim 14, wherein said predetermined period of monitoring time is counting up from zero to a predetermined time by said time counter.

20. The action control device, as recited in claim 14, wherein said predetermined period of monitoring time is counting down from a predetermined time to zero by said time counter.
