Connecting a door opener
LBefore connecting to a door opener, make sure that:
– S1/S2/S3/S4 terminal: Normally open/Actively short
– The door opener is less than 30 V AC (1 A), 24 V DC (1 A).
– S1/S2/S3/S4 terminal on the main monitor station is not the power supply to the door
opener. If the door opener needs a power supply device to connect to the main monitor
station, contact the dealer where you purchased the door opener.
L The door opener for the door station connected to terminal D1/D2 must be
connected to terminal S1/S2. The other door opener for the door station connected
to terminal D3/D4 must be connected to terminal S3/S4.
L You can connect up to 2 door openers to the main monitor station. If the main monitor
station is connected to a PBX, one of the 2 door openers can be connected to the PBX
and operated from the PBX extensions.
Note:
LConnect the plug to the power outlet which is easily accessible. In case the plug is not
easily accessible, you should install the main disconnect device near the product. The main
disconnect device needs to be certifi ed or comply with an appropriate standard. (See “To
connect the plug to the power outlet which is not easily accessible”.)
LWhen you move the main monitor station, make sure the PBX is disconnected.
LThe door opener wiring schematic diagram is only an example. Refer to the wiring
instructions provided with your door opener and PBX for details.
