Connection of conventional detectors with a Conventional Zone Module
FI700/M1CZ
By means of the Conventional Zone Module FI700/M1CZ, automatic conventional detectors can be
connected to a loop with the Labor Strauss/700 protocol.
The maximum line resistance of the detection loop is 50 Ohm per wire. If a 0.5mm² wire is used, this
corresponds to a distance of approx. 1400m between the last detector and the conventional zone mod-
ule.
The alarm condition of a conventional detector zone is reset by disabling the zone for at least 10
seconds.
The maximum detector current is
5mA
.
According to the parameter setup of the fire detection control panel, either a resistive or capacitive end-
of-line element can be used (default setting: EOL Capacitor). The line can be terminated with the
enclosed
4.7µF capacitor
or the
4k7 resistor
.
The following connection diagrams are shown with a 4.7µF end-of-line capacitor.

Address setting
Detailed information can be found on page 95 in Chapter 3.3: „Address programming of loop ele-
ments“.
The Conventional Zone Module FI700/M1CZ uses one address on the loop.
3.8.2
Power supply
A separate power supply is required for the Conventional Zone Module FI700/M1CZ. The module can
be powered from the control panel, by an external power supply or via the loop itself.
The drawing below shows the position of the terminals and the possible configurations concerning the
power supply.
