Abstract

An electronic sensor package includes at least six sensor-amplifier circuits each adapted to be electrically connected to a different condition-responsive device and each electrically connected directly to a relay for energizing the relay, each of the relays being electrically connected to at least two of the sensor-amplifier circuits, whereby the number of relays to which the sensor amplifier circuits are connected is no more than half the number of sensor-amplifier circuits. The relays are electrically connected to a timing circuit electrically connected to signalling or controlling devices.

Claims

1. An electronic sensor package comprising at least six sensor-amplifier circuits each adapted to be electrically connected to a different condition responsive device and each electrically connected directly to a relay for energizing said relay, each of said relays being electrically connected to at least two of said sensor-amplifier circuits whereby the number of relays to which said sensor-amplifier circuits are connected is no more than half the number of sensor-amplifier circuits, said relays being electrically connected to a timing circuit electrically connected to signal or control means, or both.

2. The package of claim 1 wherein said condition responsive devices include a gas sensor, a proximity type intrusion detector, a photosensitive fire detector, an ionization type smoke detector, a weather detector, and a sound sensor.

3. The package of claim 2 wherein each of said sensor-amplifier circuits includes means for varying the sensitivity of said sensor-amplifier circuits.

4. The package of claim 1 including a portable housing having front, side and rear panels and an infrared sensor and a photocell intrusion detector mounted in a panel of said housing.

5. The package of claim 4 wherein said infrared sensor and photocell intrusion detector are electrically connected in sensor-amplifier circuits through jack receptacles adapted to receive jack plugs connected to different sensors and to disconnect said infrared sensor and photocell intrusion detector upon insertion of said jack plugs.
