RUN indicator O: The power supply is
abnormal.
Blinking at long intervals: The
device successfully registers
with the ECC800-Pro and the
software runs properly (the
indicator blinks at 0.5 Hz, on
for 1s and then
o for 1s).
Blinking at short intervals: The
communication is disconnected
or the device fails to register
with the ECC800-Pro (the
indicator blinks at 4 Hz, on for
0.125s and then
o for 0.125s).
Blinking: The indicator blinks at
super short intervals for 0.5s
(blinking at 10 Hz, on for 0.05s
and then
o for 0.05s) and
then turns
o for 0.5s. The
cycle lasts for 10s.
If the RUN indicator is o,
check the power supply.
If the RUN indicator blinks at
short intervals, check whether
the communications cable is
loose or disconnected. If so,
reconnect the cable.

● Semi-annual maintenance of the re extinguishing system involves system
commissioning. Before the maintenance, inform the related administrative
departments that the
re extinguishing system will be maintained and stop
working.
● Before the maintenance, disconnect all cables to re cylinder electromagnetic
valves to avoid extinguishant release and damage to equipment due to
misoperations.
● After the maintenance, reconnect the cables to
re cylinder electromagnetic
valves and inform the administrative departments that the re extinguishing
system has resumed.
