Appl. No.:

09/634972

Inventors:

William P. Tanguay - Downers Grove IL
Thomas W. Kondziolka - Chicago IL

Assignee:

Ranco Incorporated of Delaware - Wilmington DE

International Classification:

G08B 1710

US Classification:

340630, 340578, 340579, 340629, 3406932, 250384, 356338, 356339

Abstract:

A smoke alarm having both an ionization detector and a photoelectric detector coupled to each other to generate an alarm signal when either of the detectors senses a potential fire. The smoke detector includes a power supply circuit having both an AC power supply and a DC battery power supply. During normal operating conditions, the AC power supply operates both the ionization detector and the photoelectric detector of the smoke alarm. Upon power interruption, the DC battery supply provides power to operate both the ionization detector and the photoelectric detector. The smoke alarm includes an interconnect that allows multiple smoke alarms to be coupled together.

Inventors:

William Peter Tanguay - Downers Grove IL

Assignee:

Ranco Inc. - Wilmington DE

International Classification:

G08B 2900

US Classification:

340508, 340512, 340506, 340532, 3408252, 340539, 340632

Abstract:

A method and apparatus for synchronizing a series of interconnected alarm devices. The alarm device detecting an alarm condition produces a signal having a distinct rising edge which is detected at each of the remaining alarm devices. A pulsed alarm signal having a fixed number of pulses is generated at each remaining device in response to the rising edge. A reset signal from the alarm device detecting the alarm condition resets each of the remaining alarm devices after each fixed number of pulses is produced so that each of said devices has a pulsed alarm signal which begins and ends at substantially the same time.

Inventors:

William P. Tanguay - Downers Grove IL

Assignee:

Ranco Incorporated of Delaware - Wilmington DE

International Classification:

H01H 1914

US Classification:

307115, 219719, 219492

Abstract:

A time control unit having both a time base dial that allows the user to set the cycle time duration and a duty cycle dial that allows the user to set the percentage of time a load connected to the time control unit in activated during each cycle time. The time base dial includes a series of discrete time base settings that increase non-linearly from a minimum setting to a maximum setting. The duty cycle dial also includes a series of discrete duty cycle settings ranging between a maximum and a minimum duty cycle value. The amount of increase in the percentage of the cycle time between successive duty cycle settings is smaller near the minimum (0%) and maximum (100%) settings and larger near the midpoint between the minimum and the maximum settings such that the duty cycle dial has greater resolution near the maximum and minimum settings.

Inventors:

William P. Tanguay - Downers Grove IL

Assignee:

Maple Chase Company - Downers Grove IL

International Classification:

G08B 2900

US Classification:

340514, 340506, 340516, 340 31

Abstract:

An adverse condition detect or that allows the user to test the apparatus in close proximity without having to endure full operational alarm activation. The adverse condition detector includes a detector, a transducer and a test system. When the detector senses an adverse condition, the transducer is activated to generate an alarm signal having an alarm level. When the test switch is activated, a test signal is generated at the alarm level and has a test duration that is substantially less than the duration of the alarm signal. In one embodiment of the invention, the alarm signal includes a plurality of alarm pulses having an alarm pulse duration and the test signal includes a plurality of test pulses each having a test pulse duration substantially less than the alarm pulse.

Inventors:

William P. Tanguay - Downers Grove IL, US

Assignee:

Maple Chase Company - Downers Grove IL

International Classification:

G08B017/10

US Classification:

340628, 34028605, 340577, 34081545

Abstract:

An adverse condition detector that allows the user to visually determine the type of adverse condition being detected. The adverse condition detector includes a sensor and a control unit coupled to the sensor. When the sensor detects an adverse condition above a selected level, the control unit generates an audible alarm signal and a visual alarm signal. The visual alarm signal simulates the type of adverse condition being detected. In one embodiment of the invention, the visual alarm signal includes a plurality of visual indicators operated in a random fashion to simulate the appearance of a flame.
