If the System Will Not Set
Detector Active
If you try to set the system while something is triggering one of the detectors
in the protected area (for example a door or window is still open) then the
keypads or internal sounder will give an interrupted tone and the display will
show the zone number of the detector.
1. Go to the zone shown on the display and find out what is
triggering the detector. If possible remedy the fault.
2. Return to the keypad and set the system again.
If no other detectors are active the system sets.
3. Repeat steps 1 to 2 if the display shows other zones.
4. If you still cannot set the system then call the Installer.
Other Faults (Service Lamp Glowing)
If the control unit detects a technical fault then it lights the
s
lamp on the
keypad to warn you that there is a problem. (If the fault disappears the
control unit switches the
s
lamp off.) The keypad sounds a soft intermittent
"beep" to draw your attention. This attention tone continues even if the
s
lamp goes off. To indicate the nature of the fault the control unit makes an
entry in the log and displays a short text warning on the keypad when you
next enter an access code to set the system.
To acknowledge the warning, press
Y
. The control unit removes the warning
message from the display and silences the attention tone. You can carry on
and set the system.
For example, if the mains supply is interrupted then
s
on the keypad glows
and the
a
lamp flashes. When you next enter your access code to set the
system the keypad display shows the words:
1. Press
Y
.
The keypad display shows:
2. Carry on and set the system as normal.
If you still cannot set the system after acknowledging a warning then call the
Installer.
Note: If the mains electricity supply fails then you can still set the system. Key in your
access code and press
Y
then press A, B, C or D followed by
Y
.
