ANALOGUE LOOP(S)
The Analogue Loop provides the connection to all the analogue addressable devices and loop powered sounders. Unless
the loop is completed the panel will not be able to monitor its integrity (open and short circuit monitoring).
Devices that can be fitted into the Analogue Loop include smoke sensors, heat sensors, Zone Monitoring Units (ZMU), I/O
units, loop sounders and manual call-points.
Refer to devices manual for connections diagrams. If no manual is available, make the connections as shown below:
NOTE:  A maximum of 32 manual call-points can be fitted into an Analogue loop. If this value is
exceeded, the response time for certain types of call-points will be excessive.
For integrity of transmission paths, it is recommended the usage of short-circuit isolators on the Analogue Loop.
Such application is directly related with an installation physical layout, and should be applied accordingly in a way to limit the
consequences of faults in the Analogue Loop.
The accepted consequences of faults using short-circuit isolators are specified in national guidelines for planning, design
and installation of fire detection and fire alarm systems (codes of practice), etc. and may vary in different countries.
Nevertheless, it is recommended never to exceed 32 detection devices on the same path or zone without the usage of
short-circuit isolators. Meaning that in an event of a short-circuit, no more than 32 detection devices should be affected.
For isolator device recommendation, search “isolators” on our website. Isolator example: GFE-AD-ISO.
