Interconnection monitoring
If the enclosure housing the unit is not next to, or close coupled to, the fire panel, e.g. right next to the fire
panel enclosure or perhaps a very short (<25mm/1") section of cable conduit coupling the enclosures
together, then there is a requirement in EN54-21 to detect open or short circuits on the interconnection
wiring between the fire panel and the unit, as well as an indication back to the fire panel of an issue.
The power connections need to meet EN54-21 7.5.2 when the unit is fitted
in an enclosure remote from the Fire control panel.
To enable the interconnection monitoring you will need to program the
unit via the config menu, app, laptop or web portal.
12V or 24V supply input
To alarm input (pin)
You will need 1 x 3K3 and 1 x 10K resistors for each pin with DEOL interconnection
monitoring.
