c) Door opener design
The code lock can be used with fail-safe or fail-secure door
openers. Pay attention to the following during the connection
process:
- "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 connection steps for this code lock depend on the
type of door opener you wish to use. Refer to section
"b) Circuit diagrams" for information on which contacts
the door opener should be connected to.
Check which type of door opener you wish to use. 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.
