Using Codoor
Access
Enter any of the programmed codes (without pressing
) and
without touching the door handle. At each key press, an audible
signal is sounded (if the buzzer is enabled) and the red LED on the
keypad flashes once.
A click sound confirms that the code has been correctly entered.
The door must be opened within 4 seconds.
Leaving the premises
Codoor’s mechanical locking device only affects the outside door handle.
The door can always be opened from the inside as usual.
Automatic resetting
Codoor has two separate resetting systems to return the lock to the
locked position after a code has been entered.
Mechanical: the lock is reset each time the door handle is used
during access.
Electronically: the lock is reset if the handle is not used within 4
seconds of a code being entered.
This provides security against unauthorised access, since Codoor
can never be left in the unlocked position. However, it is important to
remember that Codoor should not be left in the deactivated mode (see
section Deactivation function).
Access blocking
To thwart attempts to obtain an access code by trial and error, Codoor
incorporates a blocking function to disable the unit after 16 false key
presses (four successive incorrect 4-digit codes). The unit remains
blocked until 2 correct codes are entered successively. This means that
further instructions to users are not required.
