CAST ZFP Analogue Addressable Fire Alarm Panel

5.11 Conventional Sounder Circuit(s) Wiring

Two conventional sounder circuits are provided on the Main 1 or 2-Loop PCB (dependent on model), each
circuit has a maximum rating of 1A. IF A FULL COMPLEMENT OF SOUNDERS ARE TO BE USED,
SPLIT THEM EQUALLY ACROSS BOTH CIRCUITS.
Each sounder circuit should be connected to the terminals marked SNDR1 & SNDR2 as shown in Fig.5 below
and its earth screens terminated at the back box earth bar. Plug-on 5mm connectors are provided that accept up
2
to 2.5mm cable.
Note: ALWAYS make sure the two 6k8 EOL resistors (supplied) are fitted across the terminals of the last
sounder on each circuit to allow the wiring to be monitored for open and short circuit faults. If a sounder circuit
is unused, you must still connect the resistor at the panel terminals.

5.12 Auxiliary Input Wiring

Fig.6 – Auxiliary Input Connections
Note: ALWAYS make sure the two 6k8 EOL resistors (supplied) are fitted across the terminals of the last
device on each input to allow the wiring to be monitored for open and short circuit faults. If an input is unused,
you must still connect the resistor at the panel terminals.

F – Main 2-Loop PCB
Two programmable auxiliary input
connections are provided on the Main 1
or 2-Loop PCB (which are set up
standard as Class Change & Alert).
The wiring for each input should be
connected to the terminal block marked
IP/1 & IP/2 with a 470R 0.25W trigger
resistor (supplied) in each leg, as shown
in Fig.6, left.
If required, input wiring screens can be
terminated at the earth bar in the same
way as the analogue loop earth screens.
