EN1751 Water Detector
Installation Instructions
1 Overview
The EN1751 water detector provides affordable early warning against
damage caused by leaking appliances and standing water when used with
the Honeywell® FP280 or Flair Electronics® 1010-H2OS36-EN1751 probe,
sold separately. The EN1751 water detector sends a primary alarm (alarm
1) to indicate the presence of water, and a secondary and tertiary alarm
(alarm 2 and alarm 3) to indicate other fault conditions described in section
4, “Operation” on page 2.

4. Press the reset button to initialize the transmitter.
2.3 Mount the Probe
The Inovonics EN1751 water detector is used with the Honeywell FP280 or
Flair Electronics® 1010-H2OS36-EN1751 probe. To mount the external
probe:
5. Trim the probe wiring to the desired length.
6. Route the probe wiring through either the rectangular back wiring
cutouts on the back of the housing and bracket, or through the rounded
top wiring cutout at the top of the housing.
Note: If you want to use the cutout at the top of the housing, you will need
to trim the bracket.
7. Use a small screwdriver to attach the probe wiring leads to the power
terminal block.
8. Mount the probe per manufacturer’s instructions.
9. Press the reset button to complete configuration.
2.4 Register the EN1751 Water Detector
The EN1751 water detector must be registered with the system in order to
be monitored and supervised. Refer to the receiver installation instructions
for details on registering a transmitter.
10. When prompted by the receiver to reset transmitter, press the reset
button.
11. Replace the cover.
2.5 Mount the EN1751 Water Detector
12. Attach the mounting bracket to the desired location, using the included
screws or double-sided tape.
Note: There are two mounting holes for standard installation. An optional
third mounting hole is located under the battery. Use the third mounting
hole to secure the housing to the bracket.
13. Hook the bottom of the EN1751 water detector into the bracket’s bottom
catch, and press the EN1751 into the bracket so that the bracket’s top
lip snaps into place.
14. Use staples or tape to secure the wiring between the EN1751 water
detector and the probe.
15. Test the EN1751 and probe per section 3, “Testing the EN1751 Water
Detector”.
3 Testing the EN1751 Water Detector
The EN1751 water detector should be tested weekly and after registration
to ensure operation.
To test the EN1751 water detector:
1. Inspect to ensure both the EN1751 and probe are securely mounted
and the wiring is still secured.
2. Submerge the probe in 1/4” of non-distilled water and ensure an
appropriate response.
When testing has completed, you will need to reset the EN1751. To reset
the EN1751:
1. Remove the EN1751 water detector from the mounting bracket.
2. Use your thumb to depress the housing release tab on the bottom of the
transmitter; separate the housing.
3. Press the reset button.
