FLOOD DETECTOR TX-3FS

INTRODUCTION

The Flood Detector is composed of Radio Transmitter TX-3FS and Detector FD.

It sends an alarm signal to the Base Unit when the sensing probes of the detector are immersed in the water.

INSTALLATION AND OPERATION

1. Loosen the screw of the radio transmitter TX-3FS and open the cover. Use a pair of pliers or cutter to break the

plastic of the wiring inlet (Fig. 1). Then connect the detector to the AUX Input Terminals of the transmitter PC

Board and insert two AAA alkaline batteries.

Important Notice:

In order to reset the microprocessor properly, before changing the batteries, please press the TEST button for

5 seconds to discharge the energy that remains in the capacitors of the TX-3FS. Otherwise, it may not restart

properly.

2. Select “Installer Mode” on the Base Unit, and enter Installer Password to gain access authority. Then select \Set

Device\Enroll Device\Special Sensor\Enter Zone No. to enroll the ID of the TX-3FS by pressing its TEST

button. You may change its various attributes under \Set Device\Change Device Setting\Special Sensor Change,

to fulfill different requirements.

3. Remove the paper from the double-stick tape on the back of detector’s holder, then attach the detector to the wall,

as close to the floor as possible where flooding may occur.

1. Use the base of the transmitter as a template, and mark the points on the mounting surface through the two

mounting holes. Then drill two holes and attach the transmitter base with the 2 screws supplied.

Note: - Avoid mounting the transmitter directly on the metal frame, since that would attenuate signal

transmission and shorten radio range. Keep the transmitter at least 5 cm away from the metal plate.

5. TEST: Dip the FD detector in a cup of water, or press the TEST button on the TX-3FS, to check if this activates

the Base Unit. After testing, put the wire across the wiring inlet properly, then close the top cover of the

transmitter and tighten the screw.

Note: - If the detector is tested using water, water may remain on the detector’s sensing probes, it must be

dried properly. After 1 minute, the detector can be tested with water again.
