Cloud Electronics CX163 - Manual (Page 14)

7.1 Utility Output
The CX163 is fitted with a fixed level, balanced output for utility areas such as toilets and foyers,
where it is desirable to have a fixed level signal which operates independently from the variable
outputs of Zones 1&2.
Source selection for the
utility output is achieved by
moving internal jumper J6
to the required position.
Music can be sourced from
Line 1, Zone 1 or Zone 2.
Both zone feeds are taken
before any level controls,
and the Zone 1 feed is
taken after the line 6 priority
circuitry. This means that if
Zone 1 line 6 priority is
selected and the utility
source is from Zone 1, line
6 priority will also be
effective in the utility zone.
Removing the link from
jumper J6 will turn the utility
output into a fixed level, mic
only output.
8 Remote Music Mute - Fire Alarm interface
In certain installations, such as
licensed premises or retail outlets
within a shopping mall, there may be a
local authority or fire service
requirement to mute the music signals
via a fire alarm control panel in an
alarm condition. The CX163 provides
a facility to mute the music signals
only, by using a fully isolated pair of
contacts. This is usually a relay
mounted close to the CX163, which is
powered by the fire alarm control
panel. The relay can either be closed
or opened in an alarm condition, but
the internal jumper J4 must be set to
the corresponding position:
• N/C: Normally closed means that alarm condition is when the relay opens.
• N/O: Normally open means that alarm condition is when the relay closes.
Upon leaving the factory, the unit is configured for a normally open relay connection.
When setting the jumper(s) please ensure that you:
• Remove the mains cable from the rear of the product before removing the top panel.
• Only reassemble the unit using screws identical to the original parts.
