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 zone’s Music Control Port
must be enabled by setting the adjacent push-button switch
([14] on page 9) to REMOTE (i.e., pressing it in). In this
setting, the zone’s front panel Music Level and Source Select
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 REMOTE setting may be overridden
for the
source selection control only by moving internal jumper J1
on the sub-board for the zone in question. See page 22 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 MUSIC MUTE
connector. 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 page 22). 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.
