The Gira Dual Q smoke alarm device can be equipped with a Gira relay module available as an optional extra, which enables the Dual Q smoke alarm device to be connected to external alarm devices, such as a horn or a warning light. The relay module is backward compatible and can therefore be used for Gira Dual/VdS smoke alarm devices too.
In addition, alarm and fault messages, switched to a TeleCoppler or alarm control unit, for example, can be switched or forwarded to the KNX system via a button interface.
