First Claim
Patent Images
1. A sensor alarm, for annunciating an alarm condition in response to its detection of a dangerous condition within its installed space, comprising:
- sensor means, for detecting the presence of a dangerous condition and for providing an alarm signal in response thereto; and
alarm means, including an audible annunciator and a visible annunciator, and including logic circuitry having an alarm signal protocol which, in response to the presence of said alarm signal, actuates said audible annunciator and said visible annunciator to provide a combination audible and visible alarm annunciation of the dangerous condition during an alarm interval;
as characterized by;
said logic circuitry further including an alarm origination signal protocol for providing, in response to the antecedent presence of said alarm signal, and at the conclusion of said alarm interval, pulsed excitation of said visible annunciator to provide an encoded visible annunciation of the sensor alarm as the originating source of the alarm annunciation.
