Connecting the Zones
The panels of this family have the same connections. The only difference they have is the number of the
zones and the zone relays. The common outputs, the maximum consumptions and the connection
diagrams that will be mentioned below are common to all the panels.
By default, the terminal block of each zone contains a (8
Κ
2) terminal resistor. The resistor must be
removed from the terminal block and installed on the last device of the zone or left connected on the
zones terminal block if the zone is not used.
The connections of all the zones are identical. What is shown on the next 3 diagrams for zone 1 is also
valid for the other zones.
Up to 20 devices (maximum) can be connected on each zone.
The shield of the cable that is used in the installation must be connected to the ground in order to
conform to the requirements of the electromagnetic compatibility norm (EMC).
The length of the cable must not exceed 2 km and the maximum diameter should not be more than
2mm².

. Connecting 4 detector bases to zone 1. On each base you can install BS-655, BS-660 or BS-657 detectors.
On one detector there is a BS-572 detector LED connected.

. Connecting 2 detector bases and 2 BS-536 call points to zone 1. On each base you can install BS-655, BS-
660 or BS-657 detectors.
