Filed:

Dec 13, 1999

Appl. No.:

09/459969

Inventors:

Steven L. Scorfield - Glendale Heights IL
Daniel C. Hawkinson - Elburn IL
Mark C. Bohanon - Lisle IL

Assignee:

Pittway Corporation - Chicago IL

International Classification:

G08B 2900

US Classification:

340506, 340505, 340510, 340511, 340514, 340518, 340 1031

Abstract:

An event detection system has a control element coupled to a plurality of detectors, such as smoke detectors. The control element can be implemented with a programmed processor. The detectors can include a base which removably receives a separable detector housing and electronics. Group boundaries can be specified by incorporating boundary defining electrical elements, such as switches or resistors, into either a respective detector base or into the detector itself. The control element can include instructions for carrying out an automatic addressing process with respect to the detectors. Topology information obtained during the automatic addressing process in combination with the location of the boundary defining elements specifies one or more groups for the control element. In an alternate embodiment, groups can be defined based exclusively on the topology information. In this embodiment, boundary defining electrical elements are not needed.

Abstract:

A communication protocol facilitates transmission at maximum rates for various types of cables. The protocol can be used to transmit information between a common control unit and a plurality of spaced apart devices coupled thereto. Alternately, the protocol can be used for transmission of information between devices. One control unit or device transmits clock pulses, while in a low impedance state. The devices respond to the clock pulses and transmit data on the communications link, in a low impedance state, when the source of clock pulses assumes a high impedance state. One or more features of transmitted signals can be used to implement one or more synchronized functions.

Appl. No.:

10/734961

Inventors:

Daniel C. Hawkinson - Elburn IL, US

Assignee:

Honeywell International, Inc. - Morristown NJ

International Classification:

G08B 3/00

US Classification:

3406911, 340326, 340331, 340628, 3406936, 34082536

Abstract:

An exit path indicating device incorporates at least a first port for receiving an alarm indicating signal. In normal operation upon receipt of the alarm indicating signal, the device outputs a visual or an audible, or both, indicator of the presence of an exit or egress path for use in evacuating the region. A second port disables the operation of the device. The second port can be coupled to a local sensor which provides an indication of a hazardous or alarm condition adjacent to or on the exit or egress path. If the sensor is indicating the presence of a hazardous or alarm condition, the indicating device can be disabled.

Abstract:

A projected beam smoke detector includes circuitry and control software to measure a distance a beam travels between the detector's transmitter and receiver. Either a time-based or a phase-based measurement methodology could be used. A sensitivity parameter of the detector could be set in response to the results of the measurement.

US Classification:

340630, 340511, 340501, 3406911

Abstract:

A smoke detector having a closed internal optical path can detect airborne particulate matter, such as smoke from a fire, via a light scattering sensor and/or a light absorption sensor. The path can be implemented with a plurality of reflectors, such as piezoelectric minors. Input light can be coupled to the path, on a pulsed basis, for example via one of the minors, in a resonant condition.
