Sygonix 1656670 Notice D'emploi page 33

The version with two outdoor and indoor units each may be used if your house has two entrances, for example.
The indoor unit 1 (A) and the outdoor unit 2 (B) are connected via the corresponding wires as shown in the connection
chart. Power is supplied through a plug-in mains adapter (C).
The two small DIP switches (see figure in chapter 6. a, item 13) on the rear of the two indoor units must be
set accordingly.
Indoor unit 1 (A): Upper position (= "Master")
Indoor unit 2 (B): Lower position (= "Slave")
One door opener (F and I) can each be connected directly to each of the two outdoor units (D and G)(operating
voltage 12 V), since the outdoor units provide the operating voltage at the two connection terminals "D/O" directly.
The connection terminals "GATE", in contrast, are potential-free. If another door opener is to be connected here, e.g.
for an entrance gate (E and H) to the property, provide the operating voltage with an external mains unit.
Always observe the contact resilience of the relay for the connection terminals "GATE" in the outdoor unit
(see chapter "Technical Data").
Never switch the mains voltage via the connection terminals "GATE"! There is danger to life from electric
shock!
