| 20120119921 | APPARATUS AND METHODS FOR PROVIDING EMERGENCY OVERRIDE OF INFORMATIONAL DISPLAYS - Various embodiments are generally directed to a system and method for providing emergency override of informational displays in an emergency notification system. An embodiment may include an emergency detection module coupled to a display override module. The display override module may be coupled to a third-party display driver. When an emergency condition is detected, the emergency detection module may use the display override module to override any display messages from the third-party display module in order to display an emergency display message. In an embodiment, the display override module may be a switch box. In another embodiment, the display override module may be a RSS feed subscribed to by the third-party display driver. Other embodiments are described and claimed. | 05-17-2012 |
| 20120068607 | SUPERVISION FOR A LIGHT DISPLAY DEVICE - A device and method may include, in a display device, emitting visible light in a humanly imperceptible manner and sensing said light to verify operation of the display device. | 03-22-2012 |
| 20110257940 | VISUAL NOTIFICATION TOOL - Techniques for visual notification appliance selection are described. A set of dimensions for a structure are received by a processor and stored on a computer-readable storage medium. The processor calculates a maximum distance between a mounting location for a visual notification appliance and a location within the structure based upon the received dimensions. The processor also estimates an illuminance value for each of a plurality of angular paths within the structure. A visual notification appliance is selected that has an illumination rating that produces a minimum illuminance value at the maximum distance and at each of the plurality of angular paths. Other embodiments are described and claimed. | 10-20-2011 |
| 20110242688 | ADJUSTABLE STROBE REFLECTOR ASSEMBLY - A strobe reflector that includes a reflective material and a support structure is provided. The support structure may be adjusted or moved into at least two distinct positions to provide two distinct shapes for the reflective material. The first position of the support structure shapes the reflective material in a first configuration (such as a half-hemisphere) and a second position of the support structure shapes the reflective material in a second configuration (such as a full hemisphere). The different shapes of the reflective material may be used for different mountings of the strobe device, such as for a ceiling mount or a wall mount. In this way, a single strobe reflector may be configured for different installations (whether to the wall or ceiling). | 10-06-2011 |
| 20110080280 | CONFIGURABLE NOTIFICATION DEVICE - A notification device includes a processing module configured to determine a communication mode capability of an alarm panel. The processing module communicates with the control using the determined communication mode. The notification device also includes an output module that is in electrical communication with the processing module. The output module is configured to produce an output signal in response to a signal communicated by the alarm panel. | 04-07-2011 |
| 20110025341 | GROUND FAULT DETECTION - A ground fault detection system detects an earth fault or ground fault in a network device. The network device may be used in a fire alarm network. The ground fault detection system includes a power device that electrically isolates the ground fault detection system. A controller sequences a series of switches or relays to charge an energy storing element, such as a capacitor, with the isolated power supply. The capacitor is placed in communication with each port of the network device one at a time. If the connected port includes an inadvertent connection to ground, a detection circuit will detect the bias on the earth ground. The detection circuit may then output an indication of the inadvertent connection to ground to either a workstation or a fire alarm control panel. | 02-03-2011 |
| 20100281933 | MAGNETIC RELEASING AND SECURING DEVICE - A system for securing and releasing doors includes at least two electromagnetic latches and a controller. Each of the electromagnetic latches includes a coil configured to be energized by a power signal to create a magnetic field. The controller switches the power signal between the electromagnetic latches so that the power signal is supplied to the electromagnetic latches one at a time. The electromagnetic latches may be electromagnetic door holders, electromagnetic door locks, or any combination of the two. | 11-11-2010 |
| 20100207777 | COMBINATION FIRE ALARM NOTIFICATION/EMERGENCY LIGHTING APPLIANCE - A notification appliance includes one or more high-brightness light-emitting diodes (LEDs) and a control module configured to receive commands from an external source, and in response to a first command, flash the at least one LED, and in response to a second command, turn the at least one LED on in a steady state. | 08-19-2010 |
| 20100188234 | Multiple Event Notification Appliance - An apparatus, system and method including an event notification appliance including first and second light sources configured to indicate an event, including a fire and/or alert. | 07-29-2010 |
| 20100085200 | DETECTOR - A detector comprises a detector base ( | 04-08-2010 |
| 20100026480 | FIRE GAS DETECTOR-CODING - A detector comprises a detector base and a sensor, first and second resistors connected in series, a DC voltage source (Vref) connected to the resistors, and means for monitoring the voltage at the midpoint of a potential divider constituted by the series-connected resistors. The first and second resistors are rated so that the midpoint voltage is indicative of the date of manufacture of the sensor. | 02-04-2010 |
| 20090091466 | Non-addressable dual notification appliance - The present invention provides a non-addressable notification appliance having multiple (e.g., dual) visual alarms such as strobes for notifying individuals of different types of detected events. For example, the notification appliance of the present invention could have a first strobe for indicating a fire, and a second strobe for providing mass notification of a different emergency such as a terrorist threat or attack. In one embodiment, the visual alarms could be colored differently from one another (e.g., clear and amber). In a typical embodiment, the dual notification appliance could be one of many non-addressable dual notification appliances utilized in a single alarm system that are controlled by a system controller. | 04-09-2009 |
