Notes on battery usage by x1R Smart
When x1R Smart is not powered only by batteries, but also by external power supply unit, by cable
gland spring or door sensor contacts, the batteries level behavior changes depending on
configuration type (see paragraph Options and versions). To know in advance when battery need to
be replaced, in order to avoid malfunction issues due to low or expired batteries, read the next
information related to the 3 main configurations.
A. Alkaline batteries powered
To know the battery charge, look at the battery level icon showed in the Argo app home screen,
in the opening button. Alternatively check it in in the Door Info menu.
B. DC power supply via cable gland spring plus alkaline batteries as back-up.
In this configuration batteries are seldom used: only in case of power failure from mains, usually
due to electrical energy black-out, power supply fault or wiring damage.
Batteries probably will last until their expiration date reported on it. This date need to be written
and remembered because it will probably be the replacing batteries date (indicatively 6-7 years).
To check the battery real charge proceed as follows:
1. Disconnect the external power supply cable from x1R Smart, so that it is only battery
powered.
2. Open the lock by your smartphone.
3. Check the battery charge by Argo app: look at the opening icon button or in the Door
Info menu.
C. DC power supply via door sensor contacts plus alkaline batteries.
In this configuration batteries are used only when door is open. When door is closed, x1R Smart
is always powered by door sensor contact. As consequence, the necessary energy to move the
motor is provided from the electric mains. In fact the motor maximum current absorption, that
take place during opening and closing, always happens when door is closed or ajar, so when the
door sensor contacts are touching each other.
