Multiple area smoke detector system
First Claim
1. ) Using an inverted DC voltage Pulse generated by a conventional design commercial smoke Detector (Ionization Chamber), when energize by the existence of smoke to trigger start a monostable 555 timer circuit, that generate an positive-going output voltage pulse designed for thirty seconds.

Abstract
A smoke detector system with radio frequency (rf) communication abilitiy, designed to communicate with smoke detectors in a number of different rooms or areas in the same building, by means of radio frequency (rf)signal. After the false alarm time delayed period ends, when the existence of smoke is detected, all rooms or areas are alerted of the present of smoke in the building and the individual room where smoke was detected is identified by visual signal on that smoke detector unit. The system can be reset, by manual (rf) switch on smoke detectors units or hand held (rf) remote control unit switch. System smoke detectors units used in a single building to protect, are (rf) tuned and codelocked, whereas, they communicate only with smoke detectors units in single building.

- 1. ) Using an inverted DC voltage Pulse generated by a conventional design commercial smoke Detector (Ionization Chamber), when energize by the existence of smoke to trigger start a monostable 555 timer circuit, that generate an positive-going output voltage pulse designed for thirty seconds.
-
5. ) Smoke detectors used to protect areas are embodiment with RF tuned codelocked transmitters and receivers.
- 6. ) The system contains circuitry for resetting the individual smoke detector and system. The system and individual smoke detector trigger by the existence of smoke can be reset from another smoke detector other than the one that was trigger by the existence of smoke if user desire. The system can be reset by manual RF tuned codelocked switches on commercial transmitters, or by hand held RF tuned codelocked remote control unit on commercial transmitter.
-
8. ) The development as claim in 1, 2, 3, 4, 56 and 7 can be used as an individual smoke detector with the same capability to protect a single area, by having RF tuned codelocked transmitter and receiver embodied.
-
9. ) An individual smoke detector as claim in 8, have the same capability of resetting single smoke detector with RF tuned codelocked remote control unit, and manual switch on transmitter.
