FAAC MODEL 950 BM Door Operator
11. SPECIAL APPLICATIONS
11.1. INTERLOCK
The interlock function makes it possible to control two doors (ma-
ster 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sufcient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gure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 “inter-
lock 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
rst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pushbut-
tons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gure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.
