Frequently Asked Questions - D934S Libra+ FRIEDLAND

Which battery should I use for the push button?

Use an alkaline CR2032 button cell battery. Make sure the marked '+' side is facing up.

How to install the push button?

Open the button by removing the retaining screw, insert the CR2032 battery, then screw the base to the wall or attach it with the adhesive pad. Follow the mounting diagram.

The chime does not ring, what should I do?

Check that the battery is correctly installed and fresh. Ensure the chime is within range (max 100 m in open field) and the volume is not at minimum. Re-pair the button if necessary.

Why is the orange light flashing?

A flashing orange light every 5 seconds indicates that the chime battery is low. Replace the chime batteries with fresh alkaline batteries.

What does a beep in learn mode mean?

A beep means the push button has already been programmed to this chime. To change the icon, first unlearn the button, then reprogram it.

Does the push button work with an old Libra system?

No, the Libra+ system is not compatible with the old Libra. Only use accessories marked Libra+.

Can I connect a wired push button?

Yes, the push button can act as a converter for a wired button. Refer to connection diagrams types C1 to C7 in the manual.

What is the maximum range?

The range can reach 100 meters in open field. Metal obstacles, thick walls, and cold weather conditions reduce the range.

How to replace the push button battery?

Open the housing by removing the retaining screw. Remove the old battery and insert a new CR2032 battery with the '+' sign facing up. Close the housing.

The chime beeps twice after normal ring, why?

Two beeps indicate that the battery of the push button that triggered the ring is running low. Replace it with a new CR2032 battery.

A ‘beep’ sound is heard in learn mode...The push you are programming has already been learnt by the chime.If you want to change the icon associated with the push, use the un-learn procedure, then programme the push again.

Two ‘beep’ sounds are heard after the normal chime sound...This indicates a low battery in the bell push that activated the chime. Fit a new battery, type CR2032.

When the bell push is operated, the amber confidence light does not turn on, or is only on for a short time...In normal operation, the amber light will turn on for 1 second. When the battery is weak, the light will only turn on for a short time. Fit a new battery, type CR2032.

The chime does not work...Check that the batteries are the correct type. Only use alkaline batteries.Check that the batteries are fitted correctly.The chime could be out of range of the bell push.
