Alarm Zone Wiring Diagrams
The alarm zones are wired as in the diagram below. A 10k end of line
resistor must be fitted at the end of the circuit. Motorised fire bells may
be used, but solenoid bells MUST NOT be connected to the panel.
Some electronic sounders have a choice of tones available. Please see
the sounder instructions for further information.
