COMMON PROBLEMS AND FREQUENTLY ASKED QUESTIONS
1. The Watchdog2 makes a beeping sound
a. This is usually because there is a fault or it requires attention. An LED should also be
illuminated/flashing to indicate the nature of the problem.
See below for LED functions.
The sounder can be temporarily silenced by pressing the RESET button, until the next
periodic test.
b. If there is NO green LED illuminated AND the Watchdog 2 is fitted with an optional
rechargeable battery, the sounder will beep every 10 minutes to alert to a power loss.
c. A continuous alarm tone, accompanied by the FIRE! LED indicates that it is in Fire Mode
because water flow has been detected. This normally means that a sprinkler head is open
and implies there is a fire.
2. LEDs are illuminated/flashing.
a. Refer to LED table below for more information.
3. The pump runs occasionally when there is not a fire.
a. The pump may run occasionally for a short period to maintain the pressure in the system.
This is normal.
b. The pump will run periodically (typically weekly) as part of the system’s automatic self-test.
This is normal. The time can be reset to run at your preferred time.
c. The pump runs for more than a few minutes or multiple times a week when no sprinkler
head is open,
THIS IS NOT NORMAL. Seek advice ASAP.
4. Running water can be heard or seen coming from the sprinkler system.
a. The sprinkler system is fitted with a valve which opens as part of the automatic periodic
self-test to discharge a small amount of water.
This is normal.
b. Other unplanned water discharge or leaking of the system will result in a fault alarm being
raised.
THIS IS NOT NORMAL. Seek advice ASAP.
NOTE –Sprinkler heads ONLY open when heat is applied, such as during a fire. The Watchdog2 cannot
cause the sprinkler system to operate unless there is a fire and a sprinkler head has opened.
