4. Connections
All connections to the panel must be made before connecting the battery and the
mains power supply.
Each panel has terminal blocks for connecting 16 zones of detectors, break-glass call points
or other input devices. Each zone terminal block has a pre-fitted terminal resistor (5K6). This
resistor is removed and placed on the last device of the zone or it is left in it’s place if the
zone is not used.
The connections for all 16 zones are identical. What it show in figures 4 and 5 for zone 1 is
also valid for all the other zones.

Figure 4. Connecting 1 manual call point BS-536 and 1 detector base on zone 1and connecting 2 bases of
detectors on zone 2. One detector also has a BS-572 remote LED indicator connected to it.
