False Alarms
Follow the step below when repeated
false alarms occur in a variable pres-
sure system.
Step 1. Check for and correct the
cause of continued leakage out the
alarm line drain.
Step 2. Check for and clean a clogged
alarm line drain.
Step 3. Check for and correct the
cause of a loss in excess system pres-
sure.
Step 4. Drain the sprinkler system and
re-fill it using the steps described in
the Setting Procedure section.
Intermittent Alarms
If the pressure alarm switch gives a
steady signal, but the water motor
generates an intermittent alarm, check
for binding in the water motor alarm
drive shaft.
If the water motor alarm and/or the
pressure alarm switch provide an in-
termittent alarm, it is likely the conse-
quence of an excessive amount of air
being trapped within the sprinkler sys-
tem. Drain down the sprinkler system
and refill it using the steps described
in the Setting Procedure section.
A discontinuance of an alarm may also
be caused by the Clapper closing due
to a sudden drop in supply pressure
or the shut-off of a pump in the supply
line. These types of problems can only
be corrected by maintaining a steady
supply pressure.
