Patent number: 8939013Abstract: A device and method for facilitating convenient functional testing of a duct detector is provided. The device includes a duct detector having a remote-controlled test light mounted in a housing thereof, and a detector chamber defined by a filter screen and a plurality of labyrinth members that allow light emitted by the test light to enter the detector chamber. A functional test of the duct detector can be conducted by activating the test light. If the detector is functioning properly, an amount of light emitted by the test light will be detected by the light detector, thereby simulating the presence of an excessive amount of particulate within the detector chamber. The light detector will then generate an output signal that will cause the actuation of alarms and/or the deactivation of a blower system, thereby indicating functionality of the duct detector.Type: GrantFiled: March 16, 2012Date of Patent: January 27, 2015Assignee: Tyco Fire & Security GmbHInventors: Donald D. Brighenti, Jeffrey R. Brooks

Patent number: 8794389Abstract: A system and method for logically disconnecting fire alarm equipment from elevator control equipment to enable independent testing of each equipment set. The system and method may include an interface having a fire alarm equipment side and an elevator control side which are interconnected by a plurality of relays. A plurality of action relays may be associated with specific functions of the elevator controller. A plurality of bypass relays are interposed between the action relays and the elevator controller so that when a “bypass” operation is initiated, the bypass relays prevent signals from the action relays from reaching the elevator controller. As such, the action relays can be tested without impacting ongoing elevator operations. In addition, the logical disconnection arrangement ensures proper functioning of the system once testing is completed.Type: GrantFiled: June 30, 2011Date of Patent: August 5, 2014Assignee: Tyco Fire & Security GmbHInventors: Bruce W. Marien, Jeffrey R. Brooks

Patent number: 8319625Abstract: In accordance with the embodiments of the present invention, an alarm system is provided. The alarm system includes a system controller coupled to at least one initiation device. At least one textual notification device such as for example a signboard is coupled to the system controller. In one embodiment, the textual notification device is a multi-line signboard having an alarm input and a secondary input. The textual notification device is supervised, controlled, and powered integrally with the system controller. In an additional embodiment, an audible generator can be provided that provides an audible message in conjunction with the visual message on the textual notification devices.Type: GrantFiled: September 1, 2006Date of Patent: November 27, 2012Assignees: SimplexGrinnell LP, Inova SolutionsInventors: Daniel G.

Patent number: 8023661Abstract: A self-adjusting speaker integrated with an alarm system is provided. The self-adjusting speaker may be used to aurally monitor an area (such as monitoring the ambient noise in the vicinity of the speaker) and adjust the speaker accordingly. The circumstances under which to aurally monitor a premises (such as how to monitor, when to monitor, what type of monitoring, etc.) may be varied. For example, there are several ways how to perform the aural monitoring (such as how to sense the ambient noise), including using a separate microphone or the speaker itself. A self-monitoring speaker integrated with an alarm system is also provided. The self-monitoring speaker may monitor the aural output of the speaker using a microphone or similar type of transducer. The aural output monitored by the microphone may be analyzed, and, based on the analysis, the data and/or operation of the speaker may be modified.Type: GrantFiled: February 29, 2008Date of Patent: September 20, 2011Assignee: SimplexGrinnell LPInventors: Jeffrey R. Brooks, Bernard E. H. Laluvein

Patent number: 7999666Abstract: An emergency lighting unit includes a lamp, a backup battery, controller, and a network interface. The controller connects the backup battery to the lamp upon detection of an emergency condition and loss of main power. The network interface interfaces with and receives commands from a fire alarm control panel via a fire alarm network. Each emergency lighting unit may have a unique identifier with respect to the fire alarm network.Type: GrantFiled: July 11, 2008Date of Patent: August 16, 2011Assignee: SimplexGrinnell LPInventors: Mark B. Barrieau, Johnpaul P. Barrieau, Jeffrey R. Brooks

Patent number: 7333010Abstract: A method for verifying operation of notification appliances on a notification appliance network during low input voltage conditions is provided. An output voltage is supplied to a network and is measured at a control panel. An input parameter is measured at a notification appliance connected to the network. A supply line impedance is calculated for the notification appliance based on at least one of the output voltage and the input parameter. At least one of the supply line impedance, the output voltage and the input parameter are used to determine a pass/fail condition for the notification appliance during a low voltage condition.Type: GrantFiled: November 18, 2005Date of Patent: February 19, 2008Assignee: SimplexGrinnell LPInventors: Mark P.
