WATER FLOOD DETECTOR
FD-1
fd1_en 01/12
The FD-1 water flood detector is designed to be used in spaces
where there is a risk of leakage from water installation.
Approximately 4 seconds after the water level reaches the height
at which the flood sensor electrodes are installed, the detector
starts signaling flooding (relay contacts open). A few seconds after
the water level drops below the height at which the flood sensor
electrodes are installed, the signaling stops (relay contacts close).
Explanations for Fig. 1:
1 - terminals for connecting the flood sensor.
2 - pins for switching the indicator LED on/off. Signaling by
means of the indicator LED is on, when jumper is placed on
the pins.
3 - LED indicating the relay status. It lights red when the relay is
open.
4 - tamper contact (NC). It opens when the cover is removed or
the enclosure is torn off from the wall.
5 - terminals:
+12V – power input
COM – common ground
TMP – tamper contact

The detector is monitoring power supply voltage. In case of
a prolonged voltage drop below 9 V (±5%), relay contacts open.
After restoration of minimum 9 V (±5%) voltage, relay contacts will close.

The detector is suitable for use in burglary and panic alarm systems.
1. Installation
The detector is designed for indoor installation.
1. Select the place where the detector is to be installed.
2. Open the enclosure.
3. Make a hole for the flood sensor wires in the enclosure.
4. Pass the flood sensor wires through the hole in the enclosure and screw them to the
terminals on electronics board.
5. Secure the enclosure base to the mounting surface.
6. Close the detector enclosure.
7. Test the detector for proper operation, by submerging the flood sensor in water.
8. Fasten the sensor cables and the sensor itself. The detector is ready for work.
