The BiWire Flexi Fire Detection & Alarm System
2.3 EOLM-3
Each Zone on the panel that is configured for BiWire mode
must have the intelligent end of line module (EOLM-3™)
fitted to continually monitor each zone for the presence
of fault conditions such as detector head removal, open or
short circuit and for end of line failures even when in a Fire
condition.
For new installations, any Zone on the panel that is configured
for Conventional mode can use the intelligent end of line
module (EOLM-3™) to terminate the zone but the panel will
be limited to only detecting the presence of open or short
circuit conditions to make it backward compatible with the
EOLM-1. All detector head removals will be seen as an open
circuit condition.
The EOLM-3™ module can be placed into the base of the
last manual call point or detector base.
2.4 EOLM-1
Each Zone on the panel that is configured for Standard
Conventional mode must have the intelligent end of line
module (EOLM-1™) fitted to continually monitor each zone
for the presence of fault conditions such as detector head
removal, open or short circuit and for end of line failures
even when in a Fire condition.
The EOLM-1™ module can be placed into the base of the
last manual call point or detector base.
RISK OF DAMAGE TO EOLM-3 IF CORRECT WIRING
POLARITY IS NOT OBSERVED
2.5 EOLR
Each Zone on the panel that is configured for Intrinsically
Safe Conventional mode must separate the intrinsically safe
devices from the panel using the intrinsically safe barrier
MTL5561. The last device on the zone must be terminated
with a 5K1 End of Line Resistor to ensure proper fault and
fire monitoring of the zone.
Any Sounder Circuit on the panel that is being used for
Intrinsically Safe Sounders must separate the intrinsically
safe alarm devices from the panel using the intrinsically Safe
Barrier MTL7778ac. The last alarm device on the sounder
output must be terminated with a 6K8 End of Line Resistor
to ensure proper fault monitoring of the circuit.
