b) Connecting to conventional voltage/power supply
When a conventional power supply unit should be used, observe the following figures with the wiring diagram.
A) “Fail-secure” door opener: Releases the locking latch only when its operating voltage is applied (common design
for front doors).
B) “Fail-safe” door opener: releases the locking latch only when the operating voltage is missing (uncommon design,
e.g. used for escape route doors, which can be opened in the event of a power outage).
The included diode must be connected correctly near the door opener to protect the access system from
voltage surges.

Observe the operating instructions for the alarm system used. The access system relay switches when a valid tran-
sponder is recognised. The alarm system can thus be enabled or disabled.
