Connecting Multiple PS-8RE III Units in Parallel
Parallel Maintained Mode:
To control multiple PS-8RE III units with a single remote
switch; connect the REM, +12V, and GND terminals of
all units in parallel (Figure B). Make sure that the DIP
#3 is OFF and the positions of DIP #1 and DIP #2 on all
connected units are set to the same position. Connect a
single maintained switch (such as the Furman RS-1) to
the nearest PS-8RE III.
Parallel Momentary Mode
To control multiple PS-8REIII units with multiple switches,
use Momentary mode (DIP #3 ON) and connect the REM,
and +12V, terminals of all units in parallel (Figure C) and
connect one or more momentary contact switches in paral-
lel with the REM, and +12V terminals. All connected units
will change state (from ON to OFF, or OFF to ON) each
time one of the switches are pressed.
Helpful Hint: Breaker trips or unauthorized front panel
operation can cause units operating in Momentary mode
to fall out of sync. To restore sync, press and hold the
remote switch (Figure C) for more than 4 seconds. This
Connecting Multiple PS-8RE III Units in Series
PRIMARY PS-8RE III
Series Maintained Mode
To operate multiple PS-8RE III units in series using a
single remote switch; connect a maintained contact switch
between the REM and +12V on the primary unit and con-
nect a 240VAC coil relay (TE P/N 1649341-2) between
the DELAY 3 outlet on the primary unit and the REM and
+12V pins on the secondary unit. Continue connecting
PS-8RE III units following this same pattern until all units
have been connected.
When the primary unit sequences ON the relay will acti-
vate as soon as the DELAY 3 outlet on the primary unit
has been activated. This will cause the secondary unit to
begin to sequence on.

can also be re-synced by cycling AC power to all con-

• In series mode, the DELAY 3 outlets of the primary unit
and the DELAY 1 outlets of the secondary unit will activate
simultaneously.
• When sequencing off series connected units, the sec-
ondary units will begin to sequence off as soon as the
DELAY 3 outlets on the primary unit turn off. This means
that both the primary and secondary units will sequence
off at the same time. In other words, sequencing ON and
sequencing OFF are not equivalent. If your installation
requires symmetrical sequencing please consult Furman
customer support for other product options.
