TC-U9AF-SJ/Z
ZigBee Flood Detector Installation Instructions
TC-U9AF-SJ/Z flood detector based on the detection electrode impedance
changes after flooding, through special integrated chip for water input signal
amplification, plastic, comparison, dry contact output or high and low level change
signal, just transmitter location whether there is water, and through the wireless
repeater transmission of information. The structure adopts the integrated plastic
shell design, which ensures the high reliability of the product.
This product has the characteristics of high reliability, anti-interference, high
sensitivity, fast response time and easy installation. It is suitable for
communication base station, precision machine room, library, warehouse and
other places that need alarm when there is water.

5. Daily Maintenance
5.1 Replace Battery
5.2 Cleaning and protection
The battery life is about one year. When the transmitter sends a voltage signal to the host, the battery should be replaced:
A. Hold down the card and pull the lower cover;
B. Take out the old battery and load the same type of new battery according to the correct polarity;
C. Test the effectiveness of the battery: short probe, the host under the state of protection should alarm;
D. cover the cover again.
The detector may be contaminated with dust after long-term use. At this point, it can be wiped with a wet cloth or sponge。
