Fire detection and evacuation solutions that save lives.
Installation of an XPander System
The By its nature the XPander wireless system
requires a different installation regime from
detectors which are designed to be connected
to cables, whether they are analogue
addressable or conventional detectors.
The installation must conform to a Code of
Practice for the Installation of Fire Detection
Systems, such as AS1670
-
1. The steps to be
taken when installing XPander are:
1.
First carry out a site survey and ensure
that a wireless system may be
satisfactorily installed.
2.
Install the interface in a suitable
location consistent with the site survey
and connect it to the XP95 loop.
Installations guides are provided and
should be read carefully before starting
work.
3.
Select radio operating channels
4.
Add devices, ie, detectors, call points or
alarm devices, to the interface.
5.
Install mounting plates in accordance
with the site survey and fit detector
heads to bases. Manual call points have
mounting plates which are screwed to
the wall.
Warning: Fit XPander detectors to XPander
bases only. They will be damaged if fitted to
any other type of base and will become
inoperable.
Installing the Interface
The Interface is connected to the Apollo
addressable loop in the same way as any
other interface would be.
Note that the XPander Interface is suitable for
indoor use only.
The address of the unit must be set by means
of the DIL switch. It is recommended that the
loop address number is allocated prior to the
unit being installed.
The Interface should be sited in accordance
with the survey and design details. The
recommended minimum distance between
metal objects or equipment from the aerial is
400mm. Also the recommended minimum
distance to any electrical equipment is 2
metres in all three dimensions.
The Interface has six connections:
The connections are accessed by removing
the front plate of the Interface. 20mm
knockouts are provided for cable entry.
Full installation instructions are given in the
installation guide MAN3079
Selecting Radio Operating Channels
The XPander interface uses two 915MHz
channels to communicate with the wireless
detectors and other devices.
Please refer to the Commissioning Guide for
instructions on how to select channels
Adding Devices to the XPander
Interface
Up to 31 wireless detectors or alarm signalling
devices may be assigned to a single interface.
Prior to adding devices to the Interface
batteries must be enabled, the power jumper
positioned correctly and the mounting plates
(detectors only) fitted.
During the device log
-
on routine the interface
will request confirmation of the device serial
number. This is to be found on the side of the
radio module.
Device addressing is configured using the
integral LCD display located within the Radio
Hub when deployed on site using the XPander
Hub & Cluster configuration method. The
XPERT address cards should be retained at
their default setting to allow the address tag
to be filled in during the commissioning
process. When the devices are configured and
deployed on site using the XPander Diversity
method the XPERT address cards are retained
and should be set accordingly.
The XPERT address card must be
programmed and fitted prior to assigning a
device to the interface.
In the case of sounders or sounder visual
indicators the tone must be selected using the
5
-
segment DIL switch on the base of the
sounder or sounder visual indicators.
A detailed commissioning manual, MAN3079,
is supplied with the interface.
Maintenance and Servicing
Detectors should be checked
regularly at the intervals indicated
by the locally applicable code of
practice. Ampac recommends that
the detectors be checked at least
once a year.
If detectors appear not to be
functioning correctly they should
be returned to Apollo for testing.
If detectors are externally dirty
they can be cleaned carefully with
a damp cloth using a small
amount of industrial alcohol.
Signal Strengths and Battery
Levels
These should be checked during
service visits to ensure continued
correct operation until the next
service visit. This information can
be viewed on the LCD screen of
the interface.
DirtAlert®
XPander smoke detectors have
drift compensation to compensate
for changes caused by the
environment. The most usual
change is contamination.
If the detector is dirty to the point
where
it
can
no
longer
compensate a
‘
detector dirty
’
fault
will be reported to the control
panel. Dirty detectors can be
returned to Apollo for cleaning
and recalibration.
Battery Replacement
If any device transmits a battery
warning message all the batteries
should be changed without delay.
Apollo guarantees Battery life only
guaranteed if Duracell ProCell AA
alkaline batteries are used.
