Connections
The two panels in the family have the same connections. The main differences in these panels is the number of zone
available and the number of zone relays. The common outputs, the maximum consumption and the operation
procedures are identical for all the panels.
Connecting detectors and break-glass call points to zones.
By default each zone terminal block has a pre-installed terminal resistor (5Κ6). This resistor must be removed and
installed on the last device of the zone or is left connected on the zone terminals if the zone is not used. The connections
to all the zone are identical. What is shown in figures 2, 3 and 4 for zone 1 is valid for all the zones.
The total number of connected devices per zone is 30.
All cable zones must be insulated, to earth ground, to meet EMC requirements.
The cable length for each zone must not exceed the 1.5 kilometres with a cross section cable of 1.5mm².

Figure 2.
Connecting
4 detector bases to zone 1. Each base can accept BS-655, BS-660 or BS-667
detectors. A remote indication LED BS-572 is connected to one of the detectors.
Figure 3.
Connecting 2 call points BS-536 and 2 detector bases to the same zone.

these detectors must also be connected to the terminals
24V_M
in order to be supplied with power.
