the same time, the audible warning will be going with “Zone 1 water detected” on display. Pressing
“Mute” will stop the audible warning but it will immediately start again only this time the display will be
showing “Zone 2 water detected”. This second alarm will also need the “mute” button operated to silence
the audible warning. For ease of installation and fault diagnoses both individual zone “Alarm” and “Fault
lamps have been provided internally on the top PCB.
3) Water leak detected Alarm Test
To test that the unit is functioning correctly, pressing the red “Test Zone” button to put the system into a
Water detected alarm. Using the test facility will operate the alarm relays generating a BMS alarm, and if
fitted activate of the remote beacon/sounder and close the water shutoff valve. The resulting screen can be
either (d) or (e) as shown on page 3. The displayed distance if any will be fictional.
4) Water Detected Alarm
When the detection cable comes into contact with water anywhere along its length, the audible warning
device will start, the common alarm and if fitted, the zone alarm relay will close and the display will show
the zone number and distance to the leak from the start of the detection cable. To stop the audible warning
press the “Mute Alarm” button. The system will remain in this state until the water has been removed
from the cable when the alarm relay will automatically turn OFF.
5) Sensor Fault
Because of the exposure of the detection cable on the floor, the system monitors for any breaks in the
detection cable including the interconnection cable between the control unit and the detection cable. If a
break within the cable is found, the audible warning device will start, the fault relay will operate and the
display will show the zone number. To stop the audible warning press the “Mute Alarm” push button. The
system will remain in this state until the sensor fault is repaired when the display and common fault relay
will revert back to normal. If the controller detects a break in the cable, the system will continue to detect
water up to the point of the break.
6) Water Detection Sensitivity Adjustment
To increase the sensitivity of the cable turn the potentiometer ANTICLOCKWISE, to de-crease the
sensitivity turn CLOCKWISE.
The sensitivity adjustment is provided to allow the point at which the system goes into alarm to be
adjusted. Once the system is in alarm the cable will need to be dry before any reset. It is recommended
that the sensitivity be set so that the arrow on the white plastic circle as shown above is pointing at the
3:00 clock position
