Resistor In Circuit:
Set to OFF. This switch
SW8 should only be set ON if
an external CAN bus
termination resistor is
not used
1) For full compliance with EN54-16, ISO 7240-16, BS 5839-8 and BS EN 60849, all power supplies should be monitored. This
switch should, therefore, be set to ON.
V400 – Installation Guide
DIP switch in the "OFF" position
DIP switch in the "ON" position
Function when ON
Amplifier mainframe will continue to draw
power from the batteries, even when the
battery voltage drops below 21 V.
AC mains faults ARE reported. (1)
Battery supply faults ARE reported. (1)
Aux supply faults ARE reported. (1)
Mainframe CPU faults are reported by
front panel LED latching ON.
Set to ON only if the mainframe is being
used 'stand-alone', and it is desired that
CPU reset causes LED to latch on.
Not used
Batteries CAN be connected /
disconnected remotely (e.g. from a rack
master switch using the remote battery
on/off control input), instead of the
mainframe front panel battery disconnect
switch.)
An external CAN bus terminating resistor
IS NOT used.

DIP switch position on the rear of V400
Function when OFF
Amplifier mainframe is automatically
switched off if the standby battery voltage
drops below 21 V.
This protects the battery from being
completely discharged.
AC Mains faults ARE NOT reported.
Use only when the mainframe is being
supplied from batteries only.
Battery supply faults ARE NOT reported.
Use only when the mainframe is being
supplied from AC mains only (no batteries).
Aux supply output faults ARE NOT reported.
Use only when the auxiliary DC supply output
is not being used to power other equipment.
Mainframe CPU faults not latched by the front
panel LED.
Set to OFF for all Voice Alarm applications
where the mainframes are integrated with a
VAR Router.
Not used
Batteries CANNOT be connected /
disconnected remotely.
An external CAN bus terminating resistor IS
used.
