Connections
The three panels of the family have the same connections. The main differences in these panels is the number of the
available zones and the number of the relays zones. 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 preinstalled terminal resistor (8Κ2). 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 zones 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 20.
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-657
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.
Figure 4. Connecting 3 Gas detectors BS-685 or BS-686. Besides the connections to the zone terminals
these detectors must also be connected to the terminals 24V_M in order to be supplied with power.
