Wiring Diagram - Sygonix 1698497 Bedienungsanleitung

c) Wiring diagram
Important!
If the device is operated by a power supply (and possibly an additional UPS), batteries must not be in-
serted.
The outdoor unit has a potential-free switch contact (contact load capacity, see chapter "Technical data").
Therefore either a "fail-secure" or a "fail-safe" door opener can be connected. Never switch the mains volt-
age over the connection terminals of the outdoor unit! An electric shock poses a risk to life!
A Terminal block
B External power supply (9 - 12 V/DC)
C External UPS (for example from an
alarm system, 9 - 12 V/DC)
D Voltage/power supply for the door
opener
E Door opener button in the apartment
F Fail-secure door opener (standard for
entrance doors)
G Fail-safe door opener (rare, such as
for escape route doors)

Wiring diagram for "Fail-Secure" door opener: This releases the locking
latch only when its operating voltage is applied (common design for front doors).
Wiring diagram for "Fail-Safe" door opener: It releases the locking latch only
when the operating voltage is absent (rare type, used, for example, for escape
route doors, as the door can be opened in the event of a power failure).
