Abstract: The present invention is an ASIC-controlled alarm unit. The ASIC circuit performs all the necessary control functions to provide audible and visual signaling when used with external horn and strobe circuits.

Abstract: The present invention relates to an apparatus and concomitant method for providing a splitter in a notification system. More specifically, the present invention provides a splitter, e.g., between an audio power booster and at least one notification appliance in a supervised emergency voice evacuation system.

Abstract: A contact cover for a notification appliance mounting plate is disclosed. In one embodiment, the contact cover includes a plastic body, wherein the plastic body is sized to cover less than an entire surface area of the notification appliance mounting plate, at least one piece of metal, a means for coupling said at least one piece of metal to said plastic body and one or more polarized tabs.

Abstract: A method and apparatus for providing a strobe alarm unit employing at least one light emitting diode.

Abstract: The present invention is an apparatus and a concomitant method for boosting the audio signal generated by at least one notification appliance in a supervised emergency voice evacuation system.

Abstract: A method and apparatus for providing a strobe alarm unit employing at least one light emitting diode.

Abstract: The present invention generally discloses a supervised paging, messaging background music and emergency voice evacuation system. In one embodiment, the system comprises at least one telephone zone controller and at least one telephone zone paging speaker splitter or addressable paging splitter. Specifically, telephone zone controller acts as a controlling authority for the routing and playback of audio in selectable zones. In cooperation with the telephone zone controller, the telephone zone paging speaker splitter is an addressable device that is capable of splitting an audio signal in different manners, e.g., in Class A mode or in Class B mode. The present system provides addressable functions that are not found in existing supervised paging, messaging background music and emergency voice evacuation system.

Abstract: An apparatus and concomitant method of reducing the number of synchronization pulses transmitted to the alarm units for increasing the reliability of the overall alarm system is disclosed. The synchronization signal is implemented as a reference or reset signal from which the alarm units derive a reference time to begin activation of the alarm units. Thus, when an alarm unit receives a reference synchronization pulse, the alarm unit applies the reference synchronization pulse as a reference point in time to trigger a series of flashes or audio tones. A second signal sent in close proximity to the synchronization signal is implemented to trigger a second function of the alarm units, such as a silence function.

Abstract: A method and apparatus of an alert system for notifying subscribers of weather or hazardous conditions. A weather-tracking source or service broadcasts weather or hazardous conditions across the nation to alert the general public of potentially dangerous climatic and hazardous conditions that may arise from time to time. A weather service provider receives the weather condition broadcasts from the weather-tracking source or service and transmits weather or hazardous condition signals to subscribers having an alert unit. The alert unit is a passive device capable of receiving and warning the subscribers of the weather or hazardous condition broadcasts.

Abstract: A strobe alarm has a multi-position switch for selecting a predetermined strobe intensity. The strobe alarm comprises a strobe assembly having selector switch, an indicator and a menu. The selector switch is positioned within the strobe alarm to discourage tampering. The indicator and menu are positioned in plain view for easy determination of the intensity setting of the strobe alarm.
