21) DUAL LEAF DOOR
Two automations are required to control the operation of a dual leaf swing door, one which must be setup as Master and the other that
must be setup as Slave.
In the case of overlapping leaves, setup as Master the automation applied to the first leaf which opens.
In case of swing door with two leaves overlapping when closed and installed on emergency exits, the person in charge of
commissioning shall measure the force necessary to open both leaves of the door pushing manually the Slave leaf in the
direction of the escape (most unfavourable condition).
The force necessary to open manually the door must not exceed 150N and must be measured at the main edge, at a right
angle with respect to the leaf, at an height of 1000 ± 10mm.
If the force measured is higher than the limit of 150N, apply the symbol for emergency breakout only on the main leaf
(Master) of the door.
21.1) DUAL LEAF ELECTRIC SETUP
Make the electrical connections to the automations (see paragraph "Electrical connections"), considering that the door opening control
actuators, the program selector, and the electric lock must be connected to the Master automation.
The safety sensors installed on the master leaf must be connected to the Master automation, the safety sensors installed on the slave
leaf must be connected to the Slave automation.
If the door is equipped with dual electric lock to lock individually each leaf, connect to the Slave automation the electric lock which locks
the Slave leaf.
The Master and Slave automations must be connected via the wiring "WR5MS", whose terminals must be inserted into the
connector J7 of the logic boards NEXT-L120S of the automations.
Connect to the Master automation the digital selector EV-DSEL or T-NFC.

21.2) DUAL LEAF DOOR COMMISSIONING
After having completed the mechanical installation and performed the electric connections, check manually that the motion of both leaves
is without friction for the entire run.
Before powering the system set the SW1 dip-switch of the NEXT-L120S logic board as specified in the table
