Connecting The Analogue Loop To The Main Control Pcb; Conventional Sounder Circuit Wiring - C-TEC CAST XFP Engineering Manual

Connecting the analogue loop to the Main Control PCB

One or two analogue loops are provided (model dependent) each capable of supporting up to 255
addressable devices per loop, giving 510 devices for a 2 loop panel.
Each loop should be connected to the Main Control PCB terminals marked: A+, A- (LOOP A OUT) and
B+, B- (LOOP B RETURN), as shown in Fig.5 below. The loop's earth screens should be connected to the
Main Control PCB terminals marked: Eth.

Conventional sounder circuit wiring

Two conventional sounder circuits are provided. See technical specification (page 48) for circuit
limitations. If a full complement of sounders are to be used, split them equally across both circuits.
A 6k8 end of line (EOL) resistor (provided) MUST be connected at the end of each sounder circuit to
allow the wiring to be monitored. If the sounder circuit is unused, the 6k8 resistor MUST still be fitted
at the panel terminals.
Each sounder circuit should be connected to the Main Control PCB terminals marked: S1+, S1- and S2+,
S2-, as shown in Fig.6 (page 11). Terminate earth screens at the panel's base earth distribution post, as
shown in Fig.6, page 11.
