5.1 Explanation of the control unit
Terminal/ Assignment
Function
Grid
1(GND) + 2(+12 V) Stabilized power supply 12 V DC ±4 %.
Outputs
3 + 4 Output, e. g. for electric swing door drives
Switching output Make contact
After motorized opening of the multitronic lock, the contact is switched for 2 seconds.
5 + 6 Output locking position, e. g. for alarm systems
Alarm output Break contact
Feedback signal door locked/unlocked. After opening of the multitronic lock and/or opening of
the door leaf, the contact is switched.
Inputs
7 + 8 Input 6–12 V AC / 6–24 V DC
Door opening For non-isolated opening pulses by access control systems, e. g. of intercom or building control
systems for short-time unlocking or day latch function.
Pending signal > 1 second: After opening the door leaf or after 5 seconds, the lock's latch protrudes.
The locking elements remain retracted.
9 + 10 Input potential-free
Door opening For potential-free opening pulses by access control systems for short-time and permanent
unlocking.
For the duration of the pending signal, all locking elements of the multitronic lock remain retracted,
e. g. for permanent unlocking, controlled by time switch.
11 + 12 Input potential-free
Door opening For potential-free opening pulses by access control systems for short-time unlocking or day latch
function.
Pending signal > 1 second: After opening the door leaf or after 5 seconds, the lock's latch protrudes.
The locking elements remain retracted.
13 – 15 Already occupied by the electricity and data transmission.
Input potential-free
16 + 17
Deactivation For the duration of the pending signal, all motor opening functions (control: radio receiver and input
terminals 7–12 / control in motor drive: terminals 4 and 7) are deactivated, e. g. to prevent the
motorized door opening after arming an alarm system.
Jumper DRT When the jumper DRT is removed, the output at terminal 3 + 4 remains connected as long as a
conti nuous signal at terminal 9 + 10 is applied.
Jumper TGF When the jumper TGF is removed, the locking elements, however not the latch, is retracted when
switching the input at terminal 11+12 with a signal > 1 sec.
Radio receiver For opening pulses via FUHR rolling code access control systems, refer to page 4 ff.
