1. An apparatus comprising:
- a detector that includes an ambient condition sensor, control circuits coupled to the ambient condition sensor, an output device, and a clock circuit coupled to the control circuits and configured to indicate a current time,wherein the control circuits make a detector-based determination to activate the output device responsive to a predetermined, non-alarm detector condition when the current time is within an activation window,wherein the control circuits prevent activation of the output device when the current time is outside of the activation window,wherein the activation window defines a start time of day and a stop time of the day, andwherein the predetermined, non-alarm detector condition includes a detector dirty signal or an end of life notice.

Abstract
An apparatus to set an output window includes an ambient condition detector from which non-alarm messages can be output at a pre-determined time. The ambient condition detector includes a real-time clock that can be set wirelessly by a real-time synchronizing message. A message emitting window can also be wirelessly pre-set. The non-alarm messages are emitted at respective times in the message emitting window.

19. A method comprising:
-
a detector setting clock circuitry based on time data received from a control unit; the detector receiving a window defining message from the control unit indicating a time window when the detector may activate an output device, wherein the time window defines a start time of day and a stop time of the day; the detector activating the output device in response to a non-emergency message when the time data from the clock circuitry indicates that a current time is within the time window; and the detector preventing activation of the output device in response to the non-emergency message when the time data from the clock circuitry indicates that the current time is outside of the time window, wherein the non-emergency message includes a detector dirty signal or an end of life notice.
