IOK Signal Loss
When water sensors are present and working, they send an IOK (I’m OK) signal 6 times a day (every 4 hours). In view of the fact that
these signals are brief so as to conserve battery power, sometimes they may not be received due to interference or signal overlaps.
If three consecutive signals are missed, after 12 hours the relevant LED flashes
green
. If six consecutive signals are missed over
24 hours, the LED flashes
red
, an alarm is registered, and the valve is closed. If an IOK signal is received at any time during this
24 hour period, the software resets and the flashing
green
is cancelled.
Power Loss
The control panel is equipped with a 9V standby battery. This allows operation to continue during power outages. The control panel
indicates power loss by a
red
flashing battery light. If the local standby battery reaches a critically low level, the valve will close and
remain so until the battery is replaced and the system is
reset
.
Low temperature Alarm
The control panel is equipped with a tempereature sensor. Should the ambient temperature drop to near-freezing levels (5 degrees
Celsius), the valve will be closed, and remain so until the system is reset. The battery/temperature LED should show
orange
.
