6.4 Alarm Silence Feature
When any of the fault displays is shown, the Silence key can be pressed to silence the horn. The alarm
silence feature resets after 12 hours if the fault is not corrected and reactivates the alarm.
6.5 Output Relays
When LiquidWatch detects a fault condition, it switches 1 or 2 relays. The first is the common alarm
relay. If an output relay module is installed and a relay is assigned to the probe with a fault, the output
relay for the appropriate probe number is also switched.
LiquidWatch is shipped with the relays configured to operate in a normally energized mode, so
they de-energize in the alarm state. The output relays remain switched until the fault is cleared or the
probe is taken off-line.
