GETTING STARTED

Power Supply

Door unit

With the supplied tool, loosen the screws holding the unit from the mounting

bracket. The screws are made specifically for anti-theft purposes. It is

necessary to keep the tool in a safe place for when you need it later when

replacing batteries. The door unit is powered with 8 to 12V AC or 12V DC.

Connect a power supply to the terminals (8) at the back marked with (not

included).

In case of a power failure, the unit will automatically switch to power from the

alkaline batteries (if installed).

You can use your existing doorbell transformer as power supply, as long as it

can provide 8…12V, AC or 12V DC. When you want to use another 12V

power supply, make sure it has a stable voltage output (Switching adapter

100-240VAC (V) 12VDC) and not a transformer type that has a high no load

voltage!

Backup

Insert three UM-4 size AAA alkaline cells into the battery compartment;

observe correct polarity. We strongly recommend using alkaline batteries

instead of rechargeable batteries because at low temperatures (below 0˚C),

rechargeable ones have poor performance and their capacity will fall.

Please note the alkaline batteries are used only as a backup in case of mains

failure. They can only last for 1 - 2 days under normal operation.
