d) Door opener design
The code lock can be used with fail-safe or fail-secure door openers. The operating mode must
be programmed accordingly depending on the type of door opener used.
Select "fail-safe" or "fail-secure" mode depending on the type of door opener you are using.
- "Fail-secure" door openers: Fail-secure door openers release the latch when the power
supply delivers a voltage (standard door opener type).
- "Fail-safe" door openers: Fail-safe door openers release the latch when the power supply
stops delivering a voltage (non-standard door opener type, used for emergency exit doors
so that the door opens in the event of a power cut).
The code lock modes can be programmed (see section 10 "Programming"). The default
mode is "fail secure". Refer to "b) Setting the door opener type" for more information
on how to program the door opener.
Before programming the relay mode, ascertain which type of door opener you are
using. Ensure that you do not set the code lock to fail-safe mode when using a fail-
secure door opener. Selecting the wrong mode may damage the door opener or code
lock. A fail-secure door opener requires relatively high currents for short periods in
order to open the door and is therefore not designed to be subjected to continuous
loads.
e) Door opener button with delay and warning tone
If you install a door opener button with the code lock, you may need to adjust the door opener
settings (e.g. in schools or hospitals). The behaviour of the door opener button can be configured
with or without a delay and warning tone using five different modes. For more information, see
"o) Programming the door opener button" (in section 10, "Programming").
9. Beeps and LED indicators
The three LEDs on the front side (red (2), yellow (3) and green (4)) have the following functions:
a) Red LED (2)
Turns on when the access block is activated either by an incorrect code entry or by using the
superuser code. In this state, the relay in the code lock cannot be activated by entering a user
code. The code lock can be used again after the superuser code is entered to disable the access
block and the LED turns on.
