The Loop 1-4 addressable circuits may be connected to the appropriate End 1 and End 2 terminals.
Communications normally run from Circuit End 1, but in the event of a continuity fault both ends of the
circuit will operate.
It is important that the cable screen is connected to earth at each end at the control panel only, and that the
screen continuity is maintained at all times. We recommend against the use of a 4-core cable as a loop
Feed & Return due to the possibility of data corruption.
Addressable spur (radial) circuits may be connected from any multipoint detector, but not from any other
device. Devices covering a maximum of 1 zone per spur connection may be connected to each circuit in
order to ensure that no more than 1 zone may be lost in the event of a cable failure. Full functionality is
maintained for all spur devices.
