INSTALLATION AND OPERATION MANUAL 25-16732-A November 2019 www.eaton.com
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™,
Figure 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 installed in the base of the last
manual call point or detector base.
CAUTION
IF THIS DEVICE IS NOT INSTALLED WITH THE CORRECT
POLARITY IT MAY BE DAMAGED WHEN THE PANEL IS
POWERED ON. INCORRECT POLARITY WILL ALSO CAUSE A
FAULT TO BE DISPLAYED ON THE FIRE PANEL

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™, Figure 4) 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 installed in the base of the last
manual call point or detector base.
CAUTION
IF THIS DEVICE IS NOT INSTALLED WITH THE INCORRECT
POLARITY A FAULT WILL BE DISPLAYED ON THE FIRE PANEL

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.
