11. SPECIAL APPLICATIONS
11.1. INTERLOCK
The interlock function makes it possible to control two doors
(master and slave) so that opening of one depends on closing
of the other and vice versa.
11.1.1. INTERLOCK WITH INTERNAL SENSORS
This application is recommended when the distance between
the two doors is sufficient to avoid interference in the detection
ranges of the two internal sensors.
•Make the connections between the 950I/O control units of
the two automated systems and the sensors as shown in figure
28.
•Program the following functions (see advanced progr.):
-“interlock” active on both doors,
-select the “MASTER” option for the internal door, and the
“SLAVE” option for the external one,
-select, for both doors, option “interlock without memory” or
“interlock with memory”.
Important:
•The sensors must be connected only to the Key input of the
control units;
•The interlock will operate only if both doors are set to the NIGHT
or ONE-WAY operating function.
Operation
These are the interlock operational stages:
1) The person on the outside activates sensor S1 of door A;
2) Door A opens;
3) The person enters the internal space between the two
doors;
4) Door A closes after the night pause time elapses;
5) The person activates sensor S3 of door B (If the “Interlock with
memory” option was selected, there is no need to wait for
the first door to close totally in order to activate the sensor of
the second door);
6) Door B opens;

7) The person exits;
8) Door B closes after the night pause time elapses.
The operation is identical if the person comes from the opposite
direction.
11.1.2. INTERLOCK WITHOUT INTERNAL SENSORS
This application is recommended if the doors are so near to
one another that the two internal sensors cannot be used; two
pushbuttons have to be installed for activating the doors from
the outside; no presence sensors are used.
•Make the connections between the 950I/O control units of
the two automated systems, of the pushbuttons and
additional electronic components as shown in figure 29.
•Program the following functions (see advanced progr.):
-“interlock” active on both doors,
-select the “MASTER” option for the internal door, and the
“SLAVE” option for the external one,
-select the “interlock with memory” option for both doors.
Important:
•The pushbuttons must be connected only to the Key input of
the control units;
•The interlock will operate only if both doors are set to the NIGHT
or ONE-WAY operating function.
Operation
These are the interlock operational stages:
1) The person on the outside activates pushbutton B1 of door
A;
2) Door A opens;
3) The person enters the internal space between the two
doors;
4) Door A closes after the night pause time elapses;
5) Door B opens automatically;
7) The person exits;
8) Door B closes after the night pause time elapses.
The operation is identical if the person comes from the opposite
direction.
