The FUHR multipoint locking system multitronic 881 locks doors electromotively – at all times and fully automated.

•Particularly reliable – strong and fast – due to two parallel high performance drives.

•This conserves energy as the door always closes imperviously.

•Enables secure locking of main entrance doors, apartment doors or back doors.

•Suitable for use with all door materials.

•All locking components can be operated either electromotively via a radio key, mechanically via the profile cylinder’s key, or

from the inside via the door lever handle.

•The electricity and data transfer is carried out from the door frame to the door leaf via a wireless transmission device. Spring­loaded contact pins enable the door leaf to be unhinged for e.g. for decorating purposes at any time.

The standard locking and unlocking functions in detail:

Special functions are described in chapter 6.

Locking (closing):

All locking components are locked automatically 3 sec. after the door has been closed over. (This can however in
emergency situations - e.g. in the event of power failure - also be carried out mechanically by turning the key 4 times.)

Unlocking (opening) from the outside:

•By means of the radio key provided

•Alternatively by using the free-running profile cylinder’s key (depending on the drive-gear position; 4 turns!)

•Optionally by means of another access system e.g. transponder, code lock, finger print recognition, eye scanner or similar

(release signal via potential-free contact!)

Unlocking (opening) from the inside:

•Via the door lever handle as usual

•Alternatively by using the free-running profile cylinder’s key (depending on the drive-gear position; 4 turns!)

•Alternatively by means of the radio key provided

•Optionally via a domestic intercom system (6-12 V AC!)

•Optionally via a wireless wall-mounted push-button switch

•Optionally by means of another access system e.g. transponder, code lock, finger print recognition, eye scanner or similar

(release signal via potential-free contact!)

•As well as access control systems pertaining to contemporary BMS devices (Building Management Systems) (24 V DC pro­cessor impulse!)

The locked mode is indicated by two brief acoustic signals. Simultaneously a red LED located on the control unit on the internal
side of the door indicates the locked mode. A green LED indicates the unlocked mode.

Do not operate the lever-handle during the electrical locking and unlocking procedure!

Further electrical connections are available for:

•Alarm systems

•Access control systems (fingerprint scanner, code lock, transponder etc.)

•Illuminated fixed pad handles/glazed units

•Electrically operated door openers (e.g. for disabled accessible doors = ‘barrier-free building’)

The FUHR multitronic is supplied with 3 radio keys (radio­controlled remote controls). All radio keys are copy protected
by means of a ‘rolling code system’.
The radio key with the red buttons is defined as the master
key and is needed to tune in the other radio keys. Up to 25
radio keys can be tuned in.

The radio keys are equipped with a three channel radio­controlled remote control. The individual buttons
(channels) are allocated as follows:
Centre button – Main door – Tuned in on site
Left button – Free for e.g. garage door
Right button – Free for e.g. garden gate

The radio key is equipped with a battery-operated indicator
light. The radio keys are particularly energy saving. One bat­tery suffices for approx. 50,000 operations.

Battery change:

1. Open the radio key casing with a coin.

2. Slide the battery out.

3. Insert the new battery (type: CR 2032). Note that the
Plus symbol is pointing upwards.

4. Press the radio key casing together again.

Important!

In order to ensure that the door can be

opened in the event of an emergency (e.g.
power failure), the profile cylinder key
should always be carried in addition to the
radio key.

The radio key with the red buttons serves as the master key.
Only this key has the ability to tune in or delete other radio
keys. The master radio key’s middle button has already been
tuned in at the factory to the control unit within the same set.

The master key cannot be deleted or

switched at a later stage.
The master key should therefore be
kept safely, as additional keys cannot
be tuned in or deleted should it be lost.

The FUHR multitronic control unit is equipped with a multitude of input and output sockets to connect additional compo­nents (such as e.g. transponder, eye scan, finger print, code locks, electrical swing door opener, alarm systems, facility
management systems etc.). The input and output sockets are located:

•On the frame: under the surface-mounted control unit casing’s cover plate (refer to 6.1)

•On the leaf: multi-functional jack of the FUHR multitronic drive unit (refer to 6.2).

Outlined below are some examples of the potential allocation of the control unit’s connection terminals.

Note: Equip the control unit casing mounted on the door frame with a surface-mounted cable duct
if concealed cable laying of individual external connection cables is required. Connection cables
pertaining to surface-mounted access control devices may be fed through this surface-mounted
cable duct to the FUHR multitronic control unit casing.

Terminal Assignment

1 + 2: Already occupied by the 12 V DC switching power supply unit’s power supply.
3 + 4: Output – e.g. for electrical swing door openers.

 Immediately after the FUHR multitronic lock has been opened via radio control, transponder etc., a relay

triggers the make contact for 2 seconds. This impulse is processed by the swing door opener’s control unit
and triggers the swinging movement of the door leaf.

 The “DRT” jumper can be removed if required (refer to the wiring diagram on page 36), enabling the swing

door opener’s output to be triggered just as long as a continuous signal is applied to the latch retaining
function (terminal 9 & 10).

5 + 6: Output –e.g. for alarm systems.
 Opening the door leaf and unlocking the lock triggers the related opener contact within 3 seconds. This

remains triggered until the door leaf is closed over and the lock has been locked. An alarm system control
unit processes the signal status and reports back ‘OPEN’ or ‘CLOSED’.

7 + 8: Input for 6-12 V AC (alternating current) or 6-24 V DC (direct current)
– optionally, this input can be used with two modes of operation:

 Function 1:
Standard opening with subsequent complete locking after 3 seconds

If a 1 sec. impulse is applied to this input (e.g. activated via a building management system) the

FUHR multitronic lock will open.

 Function 2:
Opening with day latch function

If a continuous signal is applied to this input (e.g. activated via a time switch) the FUHR multitronic lock

will open. Upon opening the door leaf or after 5 seconds, only the lock’s latch protrudes. All bolts remain
withdrawn as long as the continuous signal is applied.

9 + 10: Input for potential-free signals
– optionally, this input can be used with two modes of operation:

 Function 1:
Standard opening with subsequent complete locking after 3 seconds

If a potential-free impulse ≤ 1 second is applied to this input (e.g. controlled via an access control sys-

tem) the FUHR multitronic lock will open

 Function 2:
Opening with day latch retaining function

If a potential-free continuous signal is applied to this input (e.g. controlled via a time switch) the

FUHR multitronic lock will open. The latch and all bolts remain withdrawn as long as the continuous signal
is applied.

11 + 12: Input for potential-free signals
– optionally, this input can be used with two modes of operation:

 Function 1:
Standard opening with subsequent complete locking after 3 seconds

If a potential-free impulse ≤ 1 second is applied to this input (e.g. controlled via an access control sys-

tem) the FUHR multitronic lock will open.

 Function 2:
Opening with day latch function
If a potential-free continuous signal is applied to this input (e.g. controlled via a time switch) the FUHR

multitronic lock will open. Upon opening the door leaf or after 5 seconds, only the lock’s latch protrudes.

All bolts remain withdrawn as long as the continuous signal is applied.

 The “TGF” jumper can be removed if required (refer to the wiring diagram on page 36), enabling the lock’s

latch to no longer retract motor-driven upon the first day-latch activation.

13 - 15: Already occupied by the electricity and data transmission.
16 + 17: Input for potential-free signals.

 All motorised opening functions (radio receiver and control terminals 7-12) are deactivated as long as this

input remain triggered. The opening impulses via the motor's circuit board (terminal 4/7) are also deacti­vated.

6.1.1 Application examples for circuit board assignment

Application example in residential buildings:

For example the door shall be opened via radio key from
the outside. The opening is triggered from the inside by
means of an existing two-way intercom system with a
12 V AC control cable. This was, as the case may be, used
previously for an electrical door opener.

Terminal assignment:

Connect the two-way intercom system’s cables to terminal
7 + 8.

Application examples in residential/public
buildings:

The opening shall be triggered from the outside by means of
an access control system (e.g. numeric code lock or finger
print).

Terminal assignment:

Connect the access control system with potential-free
impulse (≤ 1 sec.) to terminals 11 + 12.

Application example in construction projects:

The door shall be locked during the day for example by
means of the latch only. At night the lock shall be locked both
completely and fully automatically. Opening from the out­side is triggered by means of an access control system (e.g.
numeric code lock or finger print). In addition, an electrical
swing door opener shall open the door leaf.

Terminal assignment:

Connect the time switch with potential-free continuous
signal to terminals 11 + 12 for function 2.
Connect the access control system with potential-free
impulse (≤ 1 sec.) to terminals 9 + 10 for function 1.
Connect the swing door opener to terminals 3 + 4.

27

The below-mentioned applications are merely intended as application examples of common connections. Furthermore there
is a multitude of other possible applications.

It is important that the respective switching signal (e.g. the 12 V DC impulse or the potential-free
contact etc.) is connected to the appropriate terminal.

We recommend the use of shielded cables in order to avoid interference from external sources and
ensure proper functioning.

6.2 The drive unit’s multi-functional jack

Terminal Assignment

1 + 2 + 3 Already occupied by the 12 V DC drive unit’s

power and data supply cable.

4 + 5 Input (impulse < 1 sec.) – e.g. for exter-

nal access control systems (transponders,
code locks, finger print, eye scan… etc.),

that are mounted directly on the door leaf.

 By means of either the access control

system’s control unit or by pressing a
switch, a brief potential-free contact trig­gers opening the FUHR multitronic lock.

5 + 6 Output – ideally used for the power supply of

illuminated fixed pad handles or illumina­ted glazed panels.

 Terminal 5 = GND (earth/ground) and
 terminal 6 = 12 V DC (max. 350 mA).

5 + 7 Input (impulse 1 sec.) – e.g. for code locks

or transponder systems, that are mounted

directly on the door leaf.
 Terminal 5 = GND (earth/ground) and
 terminal 7 = 12 V DC
 Input signal to open the lock = 12 V DC.

The points raised below are intended as an addition to the FUHR product information M3/3. The

importance of their compliance must be pointed out to builders and users alike. In the event of non-

compliance with these necessary instructions, faultless operation of the locks cannot be guaranteed.

The FUHR multitronic lock may only be used in conjunction with the components provided. Failure to

do so invalidates warranty issues.

7 Maintenance and care

29

All safety-relevant hardware must be checked at least annually for wear and tear and if mechanically secured. Depending on
the requirements, fixing screws must be tightened or the damaged or worn parts exchanged for original parts by a specialised
company.
Additionally all movable parts and locking points must be lubricated and their function must be checked. Only cleaning and
maintenance agents, which do not damage the corrosion protection of the hardware components, are to be used. Hardware
adjustments as well as replacing hardware components must be carried out by a specialist company.

We recommend you consider a service and maintenance contract with a specialist company.

In order to ensure perfect contact bet-

ween the contact surfaces and the

tappet contacts, we recommend

that the surfaces are treated with the

provided contact lubricant twice a year.

(The contact lubricant can be reordered under

the item no. NZ80077.)
