HUA With A Two-Way Key Fob
It is possible to start a Hold Up Alarm from a two-way key fob. However,
the Installer must enable this within the control unit. (Note that doing so will
mean that the system no longer complies with BS8243 or DD243.)
Once the Installer has enabled this feature, a Master User must also turn
this facility on, see page 101.
When the feature is fully enabled, to start a HUA from a Fob-2W-4B:
Press and hold any two diagonally
opposite buttons at the same time.
All four LEDs flash red three times.
The control unit starts a hold up
alarm. If your system is connected
to an alarm receiving centre the
control unit sends a hold up alarm
message to them. The control unit
then sends a message to the fob to
confirm that it has started a hold up
alarm.
All four LEDs glow green for three
seconds.
