2.2.4 Connecting zones
A zone output can only monitor a maximum of 20 detectors or 32 manual call
points. Every f zone has only one origin and one end. The last detector or call
point must therefore include a 4k7 Ohm end-of-line resistor. It is not allowed
to do T-offs of the line or place the end-of-line resistor in the zone output on
the main circuit board. Only if the zone is not going to be used it is necessary
to install an end-of-line resistor in the zone output.
