Frequently Asked Questions - EN1751 Inovonics

How do I pair the EN1751 with my Inovonics receiver?

Put the receiver into pairing mode (refer to receiver manual). Press the tamper switch on the detector three times within 5 seconds. The LED will flash green to confirm pairing.

What battery does the EN1751 use and how do I replace it?

The EN1751 uses a CR123A 3V lithium battery. To replace, remove the cover, replace the battery, and reattach the cover ensuring tamper switch engages.

What is the wireless range of the EN1751?

In open field conditions, the range is up to 2,000 feet (610 meters). Indoor range may be reduced due to walls and obstacles.

How do I know if the battery is low?

The detector will send a low-battery signal to the receiver. Additionally, the LED will flash red every 4 hours to indicate low battery.

Can I mount the EN1751 outdoors?

The EN1751 is designed for indoor use only. Operating temperature range is 32°F to 120°F (0°C to 49°C). Do not expose to rain or direct sunlight.

What does the LED indicator mean?

Solid green for 2 seconds on startup = normal. Flashing green during pairing = success. Flashing red every 4 hours = low battery. Flashing red rapidly = tamper alarm.

How do I test if the detector is working?

Press and hold the tamper switch for 5 seconds. The detector will send a test signal to the receiver. Check receiver for signal confirmation.

Is the EN1751 compatible with all Inovonics panels?

The EN1751 is compatible with Inovonics panels that support EchoStream 900 MHz devices. Check your panel's compatibility list.

How often does the detector report its status?

The detector sends a supervisory check-in signal every 4 hours. If the receiver doesn't receive a signal for 24 hours, a trouble condition is reported.

Can I clean the EN1751 with water or chemicals?

No. Clean with a soft, dry cloth. Do not use water, solvents, or abrasive cleaners as they may damage the device.

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 compatible probes from Flair Electronics®, 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.

2 Installation and Startup

2.1 Installation Notes

• These products are designed to be installed and maintained by professional security technicians.
- Products are intended for indoor use.
- Manually test all products weekly.

2.2 Install the Battery

1. Pry the top lip of the mounting bracket up, and lift the bracket off of the transmitter.
2. Use your thumb to depress the housing release tab on the bottom of the transmitter; separate the housing.
3. Install the new battery.
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:

1. Trim the probe wiring to the desired length.
2. 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.

1. Use a small screwdriver to attach the probe wiring leads to the power terminal block.

2. Mount the probe per manufacturer's instructions.

3. Press the reset button to complete configuration.

2.4 Select the Frequency Band

EchoStream products are able to use a range of radio frequencies, and is shipped from Inovonics set for your geographic area.

• The jumper will be set on the two pins marked NZ to set the frequency range to 921-928 MHz for New Zealand.
• The jumper will be set on the two pins marked AU to set the frequency range to 915-928 MHz for Australia.

• The jumper will be removed to set the frequency band to 902-928 MHz for North America.

• Ensure the frequency band is set for your geographic are.

• If the frequency band is not set for your geographic area, place a selection jumper on the appropriate frequency band selection pins to select Australia or New Zealand, or remove it for North America.

• If you have changed the frequency band, press the reset button to complete configuration.

Caution: When pressing the reset button, make sure you don't also touch the frequency band selection pins. Touching the frequency band selection pins while pressing the reset button can inadvertently set the single input universal transmitter to the wrong frequency band.

2.5 Program the Transmitter

EN1751 transmitters are programmed at the factory. It is not usually necessary to reprogram EN1751 transmitters. If you want to reprogram the transmission interval, the parameter can be changed using the programming header and the ACC17XX programming cable. Contact Inovonics technical services for details.

2.6 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.

1. When prompted by the receiver to reset transmitter, press the reset button.
2. Replace the cover.

2.7 Mount the EN1751 Water Detector

1. 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.

1. 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.
2. Use staples or tape to secure the wiring between the EN1751 water detector and the probe.
3. 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.

4. Replace the housing and return the transmitter to the mounting bracket.

4 Operation

The primary alarm, alarm 1, is sent when the EN1751 detects water; the other two alarms, alarm 2 and alarm 3, as well as the tamper message, are sent in the following cases:

Condition Message
Ambient temperature at or above 140°F.	The alarm 2 message will be sent.
Ambient temperature at or below -4°F.	The alarm 3 message will be sent.
Probe disconnected from Inovonics EN1751 water detector	The tamper message will be sent.

Note: If an alarm 1 message is sent and no water is present, inspect the wiring at the probe terminal block to ensure that there is no short.

Note: The EN1751 water detector cannot reliably detect frozen water.
