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.

• System in re.
D20
Control
• System healthy, no faults.
D79
Group
• Issue between the control panel and the drive(s).
Ensure EM 47 K drive group end of line is connected as
indicated above.
• Check 1.6 Amp (4402) / 3.15 Amp (4404) fuse has not
blown.
D14
Battery
• Incorrect connection of the batteries or 3.15 Amp fuse
blown.

Operational faults
Fire alarm interface:
• Conrm signal from interface is normally open volt free.
• 1kΩ triggering resistor installed as detailed on previous page.
• 10kΩ end of line resistor installed as detailed on previous page
Smoke detector:
• Ensure the 10kΩ end of line resistor is installed as detailed on previous page.
• Turn smoke detector head clockwise until a click is heard and a physical connection is made between head
and base.
Breakglass:
• 10kΩ end of line resistor installed and connections as detailed on previous page.
• Conrm the breakglass terminal connector is rmly secured onto the PCB.
• Check external signal fuse is present and has not blown.
Drive:
• Check MOT terminal connections in the control panel and local connection point.
• Test power supply from terminals A and B in control panel, minimum of 24v DC should be present on operation
(re).
• If voltage is present on operation and connections are correct, the issue is with the drive(s) and not the controls,
see drive information for assistance.
• If no voltage is present on operation, check 1.6 Amp (4402) / 3.15 Amp (4404) fuse is present and has not blown.
DIP-Switches:
• For operational set-up (including one-touch reset of system) see information on control panel data sheet.
