Temperature alarm
(A-alarm)
Indicated by red diode on the control
panel and on the master unit by a
red diode and audible signal. Right
diode flashes blue and an audible
signal is emitted on the leak detector.
Left diode flashes blue on the input
link.
Communication alarm (B-alarm)
Indicated by a yellow diode on the
master unit and control panel. The
right diode will flash red
on the leak
detector and input link. It can take
up to 6 hours before the alarm acti-
vates. Radio and bus communication
are both monitored.
Battery alarm (B-alarm)
Indicated by a yellow diode on the
master unit and control panel, and
on the leak detector by the left diode
flashing red.
External power supply to leak de-
tector and input link
Indicated by the left diode lighting
up green.
P
rogramming radio communication
on the leak detector and input link
Indicated by the right diode lighting
up and flashing green.
An alarm will immediately be displayed on the
master unit. If a leak detector sets off an alarm for
water or temperature, this alarm is immediately
sent to the master unit and the valve will close.
Communication is restricted between the units in
order to maximise battery capacity.
In the event of an alarm
If an alarm occurs, identify which unit it is for,
and the cause.
A-alarms
Reset the leak detector's water alarm by pressing
the red key on the underside of the leak detector.
The sensor may also need to be dried or the alarm
will recur.
Cut off a temperature alarm by pressing the red
key on the underside of the leak detector. The
diode stops flashing when the temperature rises
above the alarm limit. Temperature alarms from
the control panel and input link are reset automati-
cally and the diode stops flashing when the tem-
perature rises above the alarm limit. Only when
the temperature has risen over the limit on all units
for which a temperature alarm has been triggered
will the temperature alarm reset, and a new alarm
can be activated. Default alarm limit is 5°C.
Press the key on the leak detector to reset.
The max time alarm will activate unless the system
receives a signal to stop water supply after two
hours and five minutes. This is an indication that
the PIR sensor is faulty or a cable is broken. If the
max time alarm is activated, the water supply will
not be opened by a PIR sensor until the system
has been reset.
Reset an A-alarm by holding down the Open or
Close key on the master unit for 5 seconds.
Press the Open key on the master unit to reset the system.
