Conditionally variable strobe notification appliance

摘要

A strobe notification device that operates based on a sensed environmental condition is disclosed. The strobe notification device includes a programmed candela setting, programmed locally at the strobe notification device or programmed remotely and sent to the strobe notification device. Based on the sensed environmental condition, one or more aspects of the operation of the strobe notification device may be modified to operate the strobe of the strobe notification device at least at the programmed candela settings. For example, the intensity, duration of the pulse, or pulse width modulation of the strobe may be modified, based on the sensed environmental condition, to produce a candela output greater than the programmed candela setting. As another example, the intensity, duration of the pulse, or pulse width modulation of the strobe may be modified, based on the sensed environmental condition, to produce a candela output that is equal to the programmed candela setting.

主权项

1. A strobe notification device for use in an alarm system, the strobe notification device comprising:
a communication interface; a strobe element; and a controller in communication with the communication interface and the strobe element, the controller configured to:
determine a candela setting programmed for the strobe notification device, the programmed candela setting selected from a plurality of available candela settings;receive one or more signals indicative of a parameter pertaining to an environmental condition;select, based on the one or more signals indicative of the parameter pertaining to the environmental condition and from a plurality of pulse durations, a duration of a pulse of the strobe element such that the strobe element operates at least at the programmed candela setting;receive, via the communication interface, a command to activate the strobe element; andin response to receiving the command, use the selected duration of the pulse in order to control the strobe element to operate the strobe element at least at the programmed candela setting.
