Line
• Indicates an issue between the control panel and
control elements (re alarm interface, smoke detector
or breakglass, line button in ‘off’ position).
• Each control element requires a single 10kΩ end of line
resistor. See above detail.
• If no re alarm interface or smoke detector in system,
leave 10kΩ end of line resistor in RM terminals “R” & “-”.
• Check external signal fuse has not blown.
• Ensure line button at top of panel is in ‘on’ position at
all times.

Operational Faults Troubleshooting

Fire Alarm Interface Faults

Confirms signal from interface, 1kΩ trigger resistor, and 10kΩ end of line resistor.

Smoke Detector Faults

Ensures correct installation of 10kΩ end of line resistor and physical connection of detector head.

Breakglass Faults

Checks 10kΩ end of line resistor, terminal connector security, and external signal fuse.

Drive System Faults

Tests MOT terminal connections, 24v DC supply, and checks relevant fuses for drive issues.

DIP-Switch Configuration and Reset

Refers to control panel data sheet for operational set-up and one-touch system reset.
