Before the RSL-6 will operate, the zone’s Music Control
Port must be enabled by setting the adjacent push-button
switch (

on page 9 - Rear Panel Description) to REMOTE
(i.e., pressing it in). In this setting, the zone’s front panel
Music Level and Source Select controls become inoperative.
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 (NO) or normally closed (NC) contacts via an
internal jumper (see page 23
- PCB Jumper location and
settings). The factory default setting is NO, 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.
