EATON BiWire Flexi Installation Manual (PR215-216-520-03 15-03-16, PINSTFLEXIINST) March 2016 www.eaton.com 12
Fire Relay
The fire relay provides a set of fused volt free changeover
contacts, which operate in the event of a fire condition,
these contacts are not monitored. The fire relay can be
used as Fire Alarm Routing Equipment or Fire Protection
Equipment outputs.
Fault Relay
The fault relay provides a set of fused volt free changeover
contacts, which operate in the event of a fault condition,
these contacts are not monitored. This relay has been
configured to be in fail safe mode, so in the event of total
power loss the relay contacts will be active.
Fault Relay reporting:
• Battery fault
• Mains fault
• Charger fault
• Impedance fault
• Zone faults:
• Open circuit
• Short circuit
• Detector removal
• Sounder fault
• Repeater fault
• FRE fault
• FPE fault
Interlink Relay
The Interlink Relay in conjunction with a non-latching zone
can be used to link two BiWire Flexi fire panels together
(Figure 12) or to link a BiWire Flexi to a BiWire Ultra panel.
It is recommended to use a non-latching zone in the BiWire
mode and fit the EOLM-3 at the interlink relay of each panel.
WHEN A ZONE IS BEING USED FOR INTERLINKING
PANELS, NO OTHER DEVICES ARE PERMITTED ON THAT
ZONE.
When an alarm is activated on one of the panels, the
appropriate zone will indicate on the panel detecting fire and
the interlink relay will activate. This is turn will activate the
non-latching zone on the other panel and both panels will
be in fire and all sounders on both panels will be activated.
To reset both panels, one of the panels would be manually
soft reset, which would cause the non-latching zone on the
other panel to reset as well. This would reset both panels.
