Each Alarm circuit from the panel motherboard is
connected to the IN terminals on the Alarm Relay
Board.
Each Alarm Circuit is wired out to the sounders
from the OUT terminals and the circuit is looped
back into the RETURN terminals. No EOL resistor
is required because this is already fitted on the
Alarm Relay board on the RETURN side.
