The wire to wireless translator module is a device which interfaces the hard wired, Vega intelligent-analogue loop to the Sagittarius wireless system *. It actually simply expands the analogue system, permitting the addition of fire detecting devices based on the Sagittarius wireless communication protocol for monitoring and control. The translator, as any other Vega device, is powered directly by the analogue loop, and is to be used with control panels that implement the Vega communication protocol for monitoring and control; as a matter of fact its main function is to act literally as a translator between the Vega and the Sagittarius protocols. * Vega indicates a family of addressable, hard-wired connectable, analogue-intelligent devices used in the fire detecting field which can dialogue with a control panel by the means of an adequate communication protocol. These devices use the Vega protocol. Sagittarius indicates a family of addressable, wireless connectable, analogue-intelligent devices used in the fire detecting field which can dialogue by radio with an adequate protocol translator which permits the managing of those devices by an hard-wired connected control panel as if they where part of the detecting line. These devices use the Sagittarius protocol.
