Starting a Hold Up Alarm (HUA)
A two-way remote control can be used to start a Hold Up Alarm if enabled
by an installer and by a master or admin user (see page 61).
Note: Enabling this feature means that the system no longer complies with
BS8243 or DD243.
To start a HUA from a two-way remote control:
1. Press and hold any two diagonally opposite buttons at the same time.
All four LEDs flash red three times.
2. The control unit starts a hold up alarm and, if applicable, sends the
alarms to the Alarms Receiving Centre (ARC).
3. All four LEDs glow green for three seconds. This is your confirmation
that the control unit has generated the alarm.
Using a one-way remote control
The one-way remote control has four buttons and a small LED that glows
when it transmits a signal (see Figure 6). The buttons can be programmed
as required (see page 57), but by default, three of the buttons are used to
set or unset the system.
Note that to prevent accidental operation the user must hold a button down
for at least two seconds to ensure a transmission.

Each remote control has a unique electronic identity. You can assign (see
page 37) only one remote control to each user.
