2.3. Remote Control Unit Numbers/Zone Numbers vs. Fuse Capacity
When a large current is consumed depending on the number of connected remote control units and zones,
the JP-0410's fuses (Emergency Remote Control 1 and 2 fuses) for remote control units must be replaced.
The following table shows the relationship between current consumption and zone numbers per remote
control unit.

Two circuits of fuse/power supply terminal combinations are provided for the remote control unit. The
maximum permissible current is 5 A for both circuits put together.
When replacing the fuse for the remote control unit, use the "time-lag" type fuse. Note that the fuse exceeding
5 A cannot be used because the fuse holder is 5 A in maximum rating.
