A diode (1N4004) must be installed when using a
standard power adapter for the relay and code lock,
otherwise the code lock may be damaged.
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).
