GETTING STARTED

POWER SUPPLY

DOOR UNIT

The door unit can be powered in two ways.
1. Using batteries. (power failure)
2. Using external power adapter.
1. 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 the batteries. Insert three
UM-4 size AAA alkaline cells into the battery compartment,
observing 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.
2. The Door Unit is powered with 12V DC, or 8 to 12V AC, which is
often available at the entrance (bell transformer). Connect the
power supply to the terminals
In case of a power failure, the unit will automatically switch to
power from alkaline batteries (if installed).
