Abstract
A sensor alarm which provides an alarm notification of a dangerous condition within a monitored space, further provides notice of its current state condition, from among several states, with distinct message comprising a combination of encoded audible and visible mnemonics annunciations.
Claims35
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.
A sensor alarm, of the type which originates annunciation of an alarm in response to its detection of a dangerous condition within its monitored space, and which also annunciates an alarm originated by an external sensor alarm to which it is connected for response, comprising:
- sensor means, for detecting the presence of a dangerous condition and for providing a monitored space alarm signal in response thereto;
- interconnect means, for receiving external sensor alarm signals from external sensor alarms connected 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, both individually and jointly, of said monitored space alarm signal and said external sensor alarm signal, actuates said audible annunciator and said visible annunciator, jointly, to provide 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 monitored space 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.
