Design
If a zone is large and require two amplifier
circuits, but they happen to be in separate racks
with their own EMUX card, will the signal in the
zone get out of sync?
Yes they will get out of sync. Emux cards cannot be synchronised. You
should try to rearrange the amplifier for the same zone to be in the same
rack. However if not possible you can use one rack amplifier as "master"
for a zone and feed its 100V o/p though a voltage divider into the local
input of amps of another rack (these amps being programmed to always
select the local input), but to report faults to the zone.

Where can I find a master for the zone button
naming label?
On the Fireplace under downloads/QE90. It is LB0367 and is available
as a PDF or Excel Spreadsheet.

Installation
A QE90 ECP system consist of and AMP rack
and a remote MECP and SECP every now and
again an All Amp fault LED comes up. I can be
cleared soon after. What is the problem and how
can it be fixed?
The ECP based system requires that the comms circuits are earthed at
all ends. If there is electrical earth noise between these points,
communications can fail temporarily. The all Amp fault indicates a
communications fault. The most successful solution will be to upgrade
the system to an ECM base configuration. The lack of earthing that
should be earthed can contribute see PBQ0080

Servicing
When powered up, the Alert, Evac and PA
Indicators for Zone 2 were found to be flashing
together. What does this mean?
Zone 2 has been isolated with the service isolate facility accessible via
the On-Site Programming facility. This shouldn't normally happen by
itself, but has been noted to happen occasionally, presumably because
the ECP software hasn't cleared the applicable memory location for
some reason. To clear, enter the service fault table display as outlined in
LT0088 Ch24.3 Step 6, and press the hidden key under the "LINE
FAULT" text.

Programming
A QE90 non-ECM needs to be programmed with
changes, but when connecting the PC terminal to
the SPIF and pressing enter, it returns with
unrecognisable characters. The QE90 connects
to an FIP RZDU port. How can I get it into
programming mode?
The ECP only has one serial port to connect via the SPIF or SE9004
issue C, and when set up for 1200 baud RZDU interfacing to the FIP, the
port cannot be used for programming, normally at 9600 baud. You have
to
program
it
via
the
front
panel
in
this
case.
The manual issue 4 does not make this clear but will be corrected in
future manuals.

Servicing
Building occupants are complaining that they can
hear a hissing noise from the speakers when the
room is quiet.
Ensure that the Local Input Links on the Amplifier are in the "Silence"
position unless they are terminated into a low impedance equipment
output. If the amplifier inputs are programmed for BGM or PABX, ensure
that these inputs are either shorted out if not used, or terminated into low
impedance outputs from the BGM or PABX equipment.
