Connecting an RL-1 Series remote control plate
Wire the remote control plate as shown below. Either
single-core screened or twin-and-screen cable may be used;
in the case of the latter, ignore one of the cores. Maximum
reliable cable run is 100 m.

SINGLE-CORE SCREENED CABLE MAY BE USED
Before the RL-1 will operate, the
RSL-6
port must be enabled
by setting the adjacent
LOC/REM
push-button switch ([16]
on page 9
) to REM (i.e., pressing it in). In this setting, the
front panel
MUSIC LEVEL
and
SOURCE
controls become
inoperative. As music source selection will still be required
from the mixer’s front panel when an RL-1 is in use, the REM
setting may be overridden for the source selection control
only by moving internal jumper J14 to FR on the internal PCB.
See page 20 for location of internal jumpers.
Connecting an RSL-6 Series remote control plate
Wire the remote control plate as shown below. Twin-and-
screen cable should be used. Maximum reliable cable run is
100 m.

Music Mute
External muting of music is available at the
MUTE
CONTACTS
connector ([17] at “Description of rear
panel” on page 9
). National or Local Authority regulations
governing such systems may require that normal programme
material (i.e., music) should be muted in an emergency, to
ensure that any emergency messages are clearly audible.
The Music Mute input is on a 2-pin 5 mm-pitch screw-terminal
connector. It should be connected to the appropriate alarm
output on whichever building management system registers
the alarm (typically the Fire System). The alarm output must
be volt-free; if no such output is available, an intermediate
relay or other isolation device must be installed between the
alarm output and the Music Mute input.
The Mute input can be set to operate on either normally
open (N/O) or normally closed (N/C) contacts via an internal
jumper (see “PCB jumper location and settings” on page 20
).
The factory default setting is N/O, thus requiring a short-
circuit to be applied across the two pins of the connector for
muting to occur.
Visual indication of muting being activated is given by the
MUSIC MUTE
LED on the front panel.
