cable. Strip the sheathing and cores as necessary.
Start connecting at the remote End of Line unit and work back towards the
control panel. Connect the Amber and Blue of the cable to PA and PB
respectively. Fit a link in the terminals marked EOL. Connect the battery.
The unit should bleep. This will be repeated every 10 secs.. Re-assemble
the unit onto the back box. Refit the glass - the sounder will give a double
whoop within 10 secs. to confirm correct installation. Refit and secure the
front cover. If on fitting the glass and cover a long tone followed by double
bleeps every 5 secs. this indicates that there is a problem on the previous
section. This could be: a short or open circuit on the cable, a reverse
connection, no battery in the previous unit or no EOL link fitted.
At the next unit connect the Amber and Blue of the cable from the End of
Line unit to EA and EB respectively of this unit. Connect the Amber and
Blue of the cable leading towards the control panel to PA and PB
respectively. Reassemble the unit as above and check for the double
whoop on this unit.

Repeat the above procedure at each unit. Do NOT start to connect the next
call point until you have heard the double whoop confirmation. At the
control panel connect Amber and Blue to EA and EB respectively. Ensure
that the keyswitch is in the RESTART position. Connect the batteries
(observe the correct polarity). The green system healthy LED should start
to flash within 10 - 15 secs.. Fit the control panel front onto its back box. If
the green LED does not flash check the batteries and cable connections in
the control and the first call point.

Fault Finding

Fault indication is given audibly and visually at the control and

can be caused
by exhausted or partially exhausted batteries, cable connections or cable
damage. If fault indication occurs on installation or on extending the system it
could be that the end of line link is not fitted or two have been fitted.
Switch to TEST MODE, any call point with a partially exhausted battery will
give a single high pitched bleep at 5 sec. intervals. Remove the callpoint and
replace the battery while in TEST MODE. All Callpoint and Control panel
batteries should be changed.
A double high pitched bleep every 5 secs. indicates that there is a cable fault
between the bleeping unit and the next unit towards the end of line. This
could also indicate a totally exhausted battery in the next unit.
Any battery replacements or cabling alterations should be done with the
keyswitch in TEST MODE otherwise it will be necessary to follow the
installation procedure above.
If only part of the system is sounding as a fire condition and it is not possible to
silence it from the control this would indicate that a cable has been damaged
and it is not possible for the silence signal to be received. In this case it will be
necessary to remove the batteries from the sounding call points and follow
the installation procedure above.
NOTE: The GX32CIE is not able to silence smoke alarms that are still
sensing smoke. If it is not possible to silence the call points beyond this
detector this would indicate that some of the batteries are approaching the
battery fail point. It will be necessary to clear the smoke first.

NOTE

Smoke alarms, where fitted, can
only be used between callpoint/
/sounder units. Only one can be
fitted between each as shown. Thus
32 smoke alarms would require 32
callpoint/sounder units.
Smoke alarms cannot be used at
the end of line.
Smoke alarms are provided with a
GX32S/1 termination unit to provide
the necessary termination
resistance for the GX32 system

GX32 is available in kit form but
individual components can be
purchased as required.

GX32 Fire Alarm System

1. Overview

The GX32 fire alarm system has been designed to meet the
requirements of the Work Place regulations for electrically powered fire
alarm systems. As a manual system the GX32 complies with BS5839
Pt.1 AppG and also BS5839 Pt.6 Grade C for battery powered smoke
alarms when used with the optional interlinkable smoke alarms.
Because each Callpoint/Sounder has its own battery and
comprehensive cable monitoring between all units, the system sections
will continue to function individually even if the cables are cut or short­circuited. For this reason more economical cable can be used than is
possible with conventional fire alarm systems.
Battery life is approximately 12 months but will depend upon usage. A
battery fault monitor is incorporated in each Callpoint/Sounder and the
Control Panel.
Up to 32 GX32MCP Callpoint/Sounders can be connected to a
GX32CIE. The system must be connected as shown in the
accompanying wiring diagram. It is NOT possible to use spur wiring. The
polarity of the wiring is important.
A battery fault in any callpoint/sounder will be reported as a fault to the
GX32CIE. However although the GX32SMi smoke alarms have a battery
fault this will only give local warning it will NOT be reported to the
GX32CIE.
