19. Power supply
The control panel requires a 230V (+10%/-15%), 50/60Hz, AC mains power supply which connects to the fused
terminal block labelled “230V”.
Panels with a 3A power supply have a 20mm, F1.6A L250V mains fuse.
Panels with a 4A power supply have a 20mm T2A L250V mains fuse.
These fuses should only be replaced with fuses of the same or similar types.
The table below shows the power supply rating and recommended battery capacity for each model in the Sigma
XT+ range.
Model Description Power supply rating Batteries recommended
for 24 hour standby
K21021M3 Two zone single area 3A 7Ah
K21041M3 Four zone single area 3A 7Ah
K21042M3 Four zone two area 3A 7Ah
K21081M3 Eight zone single area 3A 7Ah
K21082M3 Eight zone two area 3A 7Ah
K21083M3 Eight zone three area 4A 12Ah
K21084M3 Eight zone four area 4A 12Ah
The maximum loading on the power supply must be carefully considered when connecting externally powered
equipment such as sounders and solenoids.
Exceeding the maximum power supply rating may cause a fuse or other protective device to operate
and render the equipment inoperative until the fuse is replaced or protective devices are reset.
The tables below can be used to calculate the loading for all models by adding the loads in the second column.
