One embodiment of a method for activating a stimulus on a notification device includes encoding an instruction to activate the stimulus in a voltage dropout pulse of a synchronization protocol and sending the synchronization protocol, including the voltage dropout pulse, over a single two wire circuit to which a fire notification device and a mass notification device are coupled, where the notification device is the fire notification device or the mass notification device.

Method and apparatus for activating and controlling fire and mass notification visual devices

A wall notification device described herein can draw a lower current by providing a more efficient reflector configuration. The reflector is designed to be positioned on a wall and provide sufficient light output in each of the requisite directions, as required by the UL 1971 standard. The notification device has a reflector unit having a base having a curved portion centered on the vertical axis and a flat portion extending from the curved portion; a reflective flange extending from a location near a top side of the base; a first and second specular protrusion extending from the curved portion of the base; a third and fourth specular protrusion extending from the base; a fifth and sixth specular protrusion extending from the curved portion of the base; and a sixth and seventh specular protrusion extending form the flat portion of the base.

Optically efficient notification device for use in life safety wall strobe applications

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.

Method and apparatus for providing an ASIC controlled alarm unit

A ceiling notification device has a housing; a reflector unit mounted to the housing; a lens positioned over the reflector unit; and a lamp in the center of the reflector unit along the central axis. The reflector unit has a base, a plurality of reflective fins, and a surface portion. The base has a curved surface that is symmetrical about a central axis. The plurality of reflective fins each has a first fin portion extending from the base and a second fin portion extending from the base and the first fin portion, the second fin portion having an inner surface and an outer surface, wherein the inner surface is exposed to the central axis. The surface portion extends from the base and positioned between the first fin portion and an edge of the base and is angled toward an inner surface of the second fin portion.

Optically efficient notification device for use in life safety ceiling strobe applications

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.

Method and apparatus for boosting an audible signal in a notification system

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.
