The present invention relates to a voice alarm device which forms part of a fire alarm system loop. Upon detection of a fire, a control panel instructs appropriate voice alarm devices to retrieve relevant audio from local storage and output the audio via a local speaker.

Voice alarm device

A voice alarm notification device of a fire alarm system, comprising: a network port for receiving an alarm notification signal; an audio file library in which the audio files include audio voice message files; a speaker; a processor unit connected to the network port for processing an alarm notification signal and for selecting one of the audio files from the library to be played through the speaker; and a Bluetooth module for establishing a Bluetooth communication link to the voice alarm notification device, via which link an audio voice file can be received. The device is arranged to add the audio voice file received via the Bluetooth communication link to the library so as to be available for selection by the processor unit when it receives an alarm notification signal.

Voice alarm notification device

A fire alarm panel comprises a panel interface. The panel interface includes a display screen, a plurality of discrete condition lights separate from the display screen, and a touchscreen panel extending across both the display screen and the plurality of condition lights.

Alarm panel

An interface circuit of a sub-system of a distributed fire detection system having a plurality of sub-systems, wherein the plurality of sub-systems are in communication with each other in a loop configuration to allow data signals to be routed between said sub-systems. The interface circuit connects the internal components of a sub-system to the external bus line connecting all components via at least three input/output ports. It comprises hardware logic components, namely switches and switch controllers listening for incoming data and opening or closing said switches to cause disconnection and connection between said input/output ports accordingly, thereby allowing the routing of data signals to one or more of the other input/output ports. The simpler configurations replaces a routing processor.
