ATTENTION: 45TRC100 wireless expander
module MUST BE POSITIONED ALWAYS AT
THE END of the conventional zone line! It is not
allowed to connect the module at the begging or in
the middle of the zone line, because that will disturb
the correct operation of the fire alarm system and is
not in compliance with the requirement of EN 54!

Control Panel
The module must be the last or the only device
connected to the conventional zone line!
The end of conventional zone line is connected to zone
input terminals of the module as strictly observing the
polarity.
The zone line EOL resistor must be fitted to zone output
terminals of the module to provide correct supervision for
alarm and fault events in the zone line.
7.3 Sounders Circuit
ATTENTION: 45TRC100 wireless expander
module MUST BE POSITIONED ALWAYS AT
THE END of the sounders circuit - the module
must be the last device connected to the line!
It is not allowed to connect the module at the begging
or in the middle of the sounders circuit, because that
will disturb the correct operation of the fire alarm
system and is not in compliance with the requirement
of EN 54!

The module must be the last or the only device
connected to the sounders circuit
The end of sounder line is connected to sounder input
terminals of the module as strictly observing the polarity.
The sounder output terminals of the module must be
terminated with resistor R* to provide correct supervision
for alarm and fault events in the sounders line circuit.
*Note: 10k resistor is required when the module is
connected to conventional ERACLE series fire alarm
panels. When the module is connected to third-party

technical manual.
7.4 Alarm Circuit
Rmcp
The zone alarm EOL resistors must be always installed
at "Fire MCP" and "Fire Det" terminals at 45TRC100
module.
The value of the resistors is calculated according the
operation voltage of the conventional zone and the fire
alarm threshold current of the used manual call points
and fire alarm detectors.
Note that, some conventional fire alarm panels are able
to distinguish the activation of manual call points and fire
alarm detectors, and other not.
Calculate the zone alarm resistor values using the
formulas:
Rmcp = Uzone / IMCP fire
Rdet = Uzone / IDetector fire
Refer to documentation of the used conventional fire
alarm control panel and used conventional detectors for
supported features, technical data and electrical values.
