FIA has developed a new technical document addressing the connection of FD&A to an ARC via a security alarm. The document has been written to make the reader aware of the implications of connecting a Fire detection and Alarm system to an ARC via an existing Security system installation and the considerations that should be taken.

Although one of the most common methods of connecting Fire Detection and Alarm systems to an ARC is using the Intruder system signalling, in these circumstances, there are some important notes to consider. It answers the question of why you would choose to use the Intruder signalling path over a dedicated communications solution for the Fire Detection and Alarm system.


• Budget limitations
• Signalling equipment choice
• Connection limitations preventing 2 systems to be used
• Size of building relative to the inefficiency of having a separate system
