US Patent:

6462655, Oct 8, 2002
Filed:

Nov 12, 1999
Appl. No.:

09/438235
Inventors:

Simon Ha - Aurora IL
Assignee:

Pittway Corporation - Chicago IL
International Classification:

G08B 2900
US Classification:

340514, 340515, 340603, 340606, 702 45, 702 50, 137551
Abstract:

A fluid flow detector test system includes a flow conduit and a pump for providing a test fluid flow at the detector. A test unit includes a programmed processor coupled to the pump by a drive circuit such as a solid state switch or a relay. The detectors output is coupled to an input port of the processor. To initiate a test, executable instructions, coupled to the processor, enable the processor to energize the pump, creating a test fluid flow. The processor senses the detectors output to evaluate its test performance. An alarm system having a plurality of detectors can include a plurality of such test systems, one coupled to each detector.

US Patent:

6661337, Dec 9, 2003
Filed:

Jan 7, 2002
Appl. No.:

10/040968
Inventors:

Simon Ha - Aurora IL
Daniel C. Scheffler - Winfield IL
Daniel J. Austin - Streamwood IL
Assignee:

Honeywell International, Inc. - Morristown NJ
International Classification:

G08B 2500
US Classification:

340293, 315120
Abstract:

Strobe control circuitry combines several approaches to limit in-rush current. One circuit limits initial circuit response to an applied voltage that has been switched from an inactive to an active state. Other circuitry switches from a high input impedance state to a low input impedance state a predetermined period of time after the applied voltage has switched to an active state.

US Patent:

6822400, Nov 23, 2004
Filed:

Jan 23, 2001
Appl. No.:

09/767897
Inventors:

Simon Ha - Aurora IL
Daniel C. Scheffler - Winfield IL
Daniel J. Austin - Streamwood IL
Assignee:

Honeywell International, Inc. - Morristown NJ
International Classification:

H05B 3702
US Classification:

315241S, 315219, 396164
Abstract:

A strobe light responds to both an input voltage range of about 8-40 volts and a selectable candela output. A programmed processor stores a plurality of electrical parameters which correspond to respective selectable candela. For repetitive fixed periods, the light is repetitively driven by a variable duty cycle signal that takes into account both applied voltage and selected candela output.

US Patent:

6856241, Feb 15, 2005
Filed:

May 5, 2003
Appl. No.:

10/429900
Inventors:

Lee D. Tice - Bartlett IL, US
Charles F. Fisler - Sycamore IL, US
Simon Ha - Aurora IL, US
Assignee:

Honeywell International, Inc. - Morristown NJ
International Classification:

G08B005/00
US Classification:

340331, 340321, 396164, 396206
Abstract:

A selectable candela strobe alarm unit includes an energy storage circuit to reliably discharge a gas filled output device. The circuit includes a primary energy storage capacitor and a secondary energy storage capacitor. The capacitors can be configured in series or in parallel to produce a selected candela output from the gas filled output device.

US Patent:

6897772, May 24, 2005
Filed:

Nov 13, 2001
Appl. No.:

10/008537
Inventors:

Daniel C. Scheffler - Winfield IL, US
Simon Ha - Aurora IL, US
Daniel J. Austin - Streamwood IL, US
Assignee:

Honeywell International, Inc. - Morristown NJ
International Classification:

G08B029/00
US Classification:

340506, 340538, 340 31, 340 32
Abstract:

A control module usable to drive audible or audible/visible output devices in an alarm system can generate a modulated pulse sequence in accordance with a desired output function. Sequence initiating pulses can be transmitted to output devices with a predetermined, substantially constant period. Additional pulses can be coupled to the output devices, between the initiating pulses, and later in time based on functions to be carried out by the output devices. The output devices in turn demodulate the received pulse train and determine the requested function which is then implemented to provide a desired audible or visual alarm indicating output.

US Patent:

7333004, Feb 19, 2008
Filed:

Sep 1, 2004
Appl. No.:

10/931630
Inventors:

Simon Ha - Aurora IL, US
Robert Asinjo - Lisle IL, US
Assignee:

Honeywell International, Inc. - Morristown NJ
International Classification:

G08B 5/00
H05B 39/00
H05B 41/00
US Classification:

340331, 34081573, 315241 P
Abstract:

A strobe unit responds to a selected candela output by selecting an optimal capacitor charging frequency to minimize current requirements at the selected candela output. A plurality of charging frequencies can be stored and associated with available input power and selected candela output.

US Patent:

7501935, Mar 10, 2009
Filed:

Oct 25, 2007
Appl. No.:

11/924364
Inventors:

Manley S. Keeler - Naperville IL, US
Charles F. Fisler - Sycamore IL, US
Simon Ha - Aurora IL, US
Assignee:

Honeywell International Inc. - Morristown NJ
International Classification:

G08B 3/00
US Classification:

3403847, 3404041
Abstract:

An audible output device, of a type usable in a fire alarm system, incorporates a multi-frequency waveform generator. The generator produces a plurality of frequencies with predetermined duty factors during various time intervals on a repetitive basis. The multi-frequency drive signal is in turn coupled to an audible output device such as a piezoelectric horn or the like. The multi-frequency audio output provides an indicator to persons adjacent to the device of the presence of an alarm condition.
