7.1 Power Supply Unit
Natron WE-C is powered only from an external power supply unit 24V DC. The power supply
terminals are connected to ±PW terminals of Natron WE-C as observing the polarity.
Natron WE-C is equipped with a special input “Inp” for Fault monitoring of the external power
supply unit. This option can be used when the external power supply unit has a special Fault
output for monitoring. According the type of the Fault output (open collector or energized) of the
external power supply unit, there are two types of connection diagrams for monitoring.
Open Collector
Diagram
When the Fault
output of the
external power
supply unit is
open collector
type, short-circuit
the “3V” output
and “Inp” input
terminals, and then
connect the Fault
Output of the
power supply unit.
Energized Fault
Output Diagram
When the Fault
output of the
external power
supply unit is
energized fault
output type,
connect it directly
to “Inp” input
terminal of the
module.
In case of power supply fault event, the conventional control panel will indicate FAULT in the zone
line to which the Natron WE-C is connected.
7.2 Conventional Zone Line
ATTENTION: Natron WE-C wireless 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!
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 with
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
7.3 Sounders Circuit
ATTENTION: Natron WE-C wireless 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
with strictly observing the polarity.
The sounder output terminals of the
module must be terminated with resistor
(R*) to provide correct supervision for
the alarm and fault events in the
sounders’line circuit.
*Note: 10k resistor is required when the
module is connected to conventional
MAG series fire alarm panels. When the
module is connected to third-party
conventional fire alarm panel, is
possible the resistor value to be
different –check this in the fire panel
technical manual.
7.4 Zone Alarm EOL Resistors
The zone alarm EOL resistors must be always installed
at “Fire MCP” and “Fire Dev” terminals at Natron WE-C
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.
