An interface for a fire alarm system having a number of alarm condition detectors (11, 12, 13), a number of alarm devices such as alarm sounders (2) and the like and a fire alarm panel (1). The interface includes a fire alarm silence controller (4) and input and output circuits (7) and (8) connected to the controller. The input circuit includes one of the detectors (11) and the output circuit, one of the alarm sounders (2). Each fire alarm silence controller (4) has a timer and a user operable device for turning off the alarm device activated by the detector. The fire alarm system is provided for a plurality of individual dwellings and each dwelling has its own interface. When a detector in one dwelling is triggered to an alarm state the corresponding fire alarm silence controller operates the corresponding alarm device but does not signal an alarm condition to the fire alarm panel.
An interface for a fire alarm system having a fire alarm panel, at least one detector for detecting an alarm condition and an alarm device corresponding to the detector wherein the interface comprises a fire alarm silence controller, an input circuit and an output circuit connected to the controller, said input circuit comprising said at least one detector and said output circuit comprising said at least one alarm device, the fire alarm silence controller being responsive to the said at least one detector such that when the detector is triggered to an alarm state the fire alarm silence controller operates the corresponding alarm device but does not signal an alarm condition to the fire alarm panel.
A method of operating a fire alarm system for a plurality of dwellings comprising a fire alarm panel and a plurality of interfaces for respective dwellings, each interface having a fire alarm silence controller connected to an input circuit having an alarm detector and to an output circuit having an alarm device including the steps of detecting an alarm condition in one of the dwellings activating the corresponding alarm device but not the fire alarm panel thereby to prevent activation of alarm devices in other dwellings.
