Abstract

An alarm or intrusion monitoring system includes a plurality of detectors which communicate with a displaced control element. Various of the detectors include local storage circuitry wherein detected conditions or events are recorded along with a time indicator. Recorded events and respective times of occurrence can be downloaded to the control element for evaluation. Detected conditions or events can include system conditions, such as faults or detector off-line indicators, as well as various intrusion or environmental-type incidents such as smoke, gas, temperature or fire.

Claims

1. A detector comprising:

an event sensor;

local control circuits coupled to the sensor; and

storage circuits coupled to the control circuits wherein the control circuits maintain indicia pertaining to a plurality of prior events in the storage circuits.

2. A detector as in claim 1 wherein the indicia include time entries for respective events.

3. A detector as in claim 1 which includes a clock coupled to the control circuits to provide time entries for respective events.

4. A detector as in claim 1 which includes at least one of a wired or wireless communications interface.

5. A detector as in claim 1 which includes a clock coupled to the control circuits to provide time entries for respective events and at least one of a wired or wireless communications interface and wherein events include sensed environmental or non-environmental incidents.

6. A detector as in claim 1 wherein the event related information is retained for a pre-determined time interval.

7. A detector as in claim 6 wherein a time parameter can be associated with event information.

8. A detector as in claim 4 with circuits to transmit event information to a displaced monitoring control unit and where the unit can transmit time related information to the detector.

9. A detector as in claim 1 where the sensors are selected from a class which includes at least, intrusion sensors, position sensors, and environmental condition sensors.

10. A regional monitoring system comprising:

a plurality of event detectors wherein at least some of the detectors include an incident sensor, local control circuits coupled to the sensor;

storage circuits coupled to the control circuits wherein the control circuits maintain indicia pertaining to a plurality of prior incidents in the storage circuits; and

a common control element which communicates with the detectors by a selected medium wherein at least some of the detectors communicate at least some of the indicia to the control element for evaluation.

11. A regional monitoring system as in claim 10 wherein at least some of the event detectors include a real-time clock and circuitry to synchronize the respective clocks with the common control element.

12. A regional monitoring system as in claim 10 wherein the control element exhibits an armed, and a disarmed status, and, wherein incidents are recorded in respective detectors only then the control element has a predetermined status.

13. A regional monitoring system as in claim 11 wherein selected ones of the detectors delete indicia in response to a predetermined criterion.

14. A regional monitoring system as in claim 10 wherein incident sensors are selected from a class which includes at least glass breakage sensors, motion sensors, intrusion sensors, infrared sensors, vibration sensors, smoke sensors, flame sensors, gas sensors, humidity sensors and temperature sensors.

15. A monitoring system comprising:

a plurality of detectors which communicate with a separate monitoring control panel;

various of the detectors include local storage circuitry wherein detected conditions or events are recorded along with a time indicator;

recorded events, and respective times of occurrence can be downloaded to the control panel for evaluation; and

detected conditions or events include at least one of, system conditions, faults, detector off-line indicators, intrusion, environmental-type events such as smoke, gas, temperature or fire.
