2 Installation Instruction
2.1 General Information:
The product must be installed by a person who has the professional knowledge required to perform
the installation correctly. Unless the installation is performed by a professional, the insurance
companies may claim that the insurance does not cover any damage that has occurred and that the
offers made by the insurance companies to the property owner are invalid.
The radio communication goes two ways between the wireless units and the central unit to secure
the quality of transmission.
The wireless units transmit a signal every 24 hours that is registered by the central unit. If no signal
is received by the central unit in 72 hours, it will warn that communication is down. A total of 16
external units can be installed, freely mixed between remote units and water sensors.
The ball valve is exercised on a daily basis through the closing/opening carried out as the water is
turned off or on. If the ball valve is open for more than three days, it will be automatically exercised,
but the water will not be completely turned off.
There are two pressure drop tests that can be conducted.
1.
The pressure drop test is conducted by taking a reference measure when the ball valve has closed
after the user has turned the water off using the OFF, delayed OFF or alarm. The system then waits
15 minutes before taking the next and final measurement. If the difference in pressure is more than
1 bar, the system considers a leak to exist and informs the user via display or LED on the remote unit.
You can choose whether to allow the water to be turned on or if the fault must first be confirmed.
2.
Automatic pressure drop test. An automatic pressure drop test is conducted once every 24 hours.
It is carried out by shutting off the water and any pressure drop in the water pipe is measured
three times with 15-minute intervals. If there is no pressure drop exceeding 1 bar in any of these
three measurements, the system will wait 24h and then do the test again. The system thus accepts
consumption on two out of three measuring occasions.
The measurement is done in the following way:
Measurement 1. The water is automatically turned off and the measurement begins. If there is a
pressure drop, the water will immediately open again and a new measurement is done 1h later.
Otherwise OK and wait 24h until next measurement.
Measurement 2. The water is automatically turned off and the measurement begins. If there is a
pressure drop, the water will immediately open again and a new measurement is done 1h later.
Otherwise OK and wait 24h until next measurement.
