Detailed Description of Preferred Embodiments General: This application is for an Innovation Patent for the integration of ionising chamber smoke detectors, passive infra red motion detectors, active infra red motion detectors, reduced instruction set computers (RISC's) and cellular telephone technology to provide an intelligent smoke detection system. The system could also be used as COMS ID No: SBMI-03318830 Received by IP Australia: Time 19:01 Date 2006-04-13 13.Apr. 2006 19:57 Wa l inston-Dummer Sydney No -49 3 P 6 -4 V\ part of an intruder alarm system for an integrated security 0 system.

c0 Functionality: Smoke Detectors: A plurality of smoke detectors 12 are positioned in the

CA

S

C ceiling of each room of a building 10 to be monitored. An on-off signal from each detector is connected to the RISC

VO

S14. The smoke detectors 12 simply denote whether smoke is present or not at each Co-ordinate (location).

Passive infra red motion detectors: These detectors 16 monitor the space in monitored room and register the presence of masses with a temperature in the region of 36.9c. A positive detection, universally from a human will also be provided to the RISC 14 as an on-off signal.

Active infra red detectors: The doorway of each monitored room will be monitored by an active infra red detector beam, with active detectors 18 installed in the plane of the inside doorjamb. Again if any mass of any temperature enters or exits the doorway and interrupts the beam, an on-off signal is dispatched to the

RISC.

This can be executed using a single IR source for doors in the same plane, eg a straight hallway. The beam can also be reflected back along the hallway for doors on the other 0\ o side of the hallway; this reduces component cost.

SRISC:

The reduced instruction set compuLor 14 establishes what is to be done with the signals received from the sensors (smoke PIR, AIR).

1. Activity: If there has been no evidence from a PIR for a "lengthy" period, it is likely that no person/s is/are in the room.

The RISC would register the room as probably empty. The likelihood of the room being empty can be checked by the infra red signals. If the external beam is broken, quickly followed by a fracture in the internal beam of a monitored room, then there is a probability that someone has entered the room. Conversely if the internal beam is broken and then the external beam, there is a high probability that a person has exited the room. In this way, coupled with intelligence from the PIR detector, a very high probability COMS ID No: SBMI-03318830 Received by IP Australia: Time 19:01 Date 2006-04-13 13 AP r 2 0 6 19 5 Wal ington-Dummer.Sydney No.4993 P. 8 -6 ND can be procured to determine whether the room is occupied O or not.

c0 2. Occupancy: The number of people in a monitored room can be ascertained from the conditions in above. Eg if the sum of entries 0\

S

c and exits can be determined for each room (which indeed it can) the arithmetic sum of total monitored rooms can then

Sbe ascerLained and will represent the number of people in the building if all space is monitored.

A further substantiation of this would be to record the activity of PIRs. If these have been zero for a "lengthy" period the building has a very high probability of being unoccupied.

3. Smoke Detection: The RISC would continuously compute activity and occupancy as a background activity until smoke detector(s) operate.

At this stage the RISC will determine whether the detection is a false alarm by successive interrogation of the smoke detector.

The individual detector would at this stage have alerted the occupants of a suspected fire by an internal piezo siren. The RISC would interrogate the detector at say seconds after the alarm and if found to be in the "off" state would take no further action, If the detector is in COMS ID No: SBMI-03318830 Received by IP Australia: Time 19:01 Date 2006-04-13 13.Apr. 2006 19:58 Wallinston-Dummer.Sydney No.4993 P. 9 7 \O the "On" condition and a further detector is in the "On" 0 0 condition there is a very high probability of fire and the a status of activity, occupancy and location will be Sforwarded by cellphone 20 (under the control of the RISC) to a security company 22 or fire brigade 24 as required.

0\ S4. Integration with a security system: The components of the smart smoke detection system lend o themselves adroitly as part of an overall security system.

The RISC can be programmed so that when occupants inform it that they are withdrawing from the building in "security mode" ie they are going to be intentionally absent. The RISC will recognize that if any P1R and AIR devices perform within a "short" period of one another, there is an intruder and can then use cell phone technology to alert the security company or police The above describes only some embodiments of the present invention and modifications, obvious to those skilled in the art, can be made thereto without departing from the scope and spirit of the present invention.
