881/881GL/ServoAccess
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 motor drives.
• This saves 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 as well as for burglary-resistant doors in accordance with EN 1627 RC 2 and RC 3.
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.)
Unlocking (opening) from the outside:
• By using the FZG free-running profile cylinder’s key (depending on the drive-gear position; 4 turns)
• Optionally by means of a FUHR radio access system e.g. transponder, finger print scanner or similar access control systems
Unlocking (opening) from the inside:
• Via the door lever handle as usual or by using the FZG free-running profile cylinder’s key (depending on the drive-gear
position; 4 turns)
• Optionally via a domestic intercom system (6-12 V AC, 6-24 V DC or potential free)
• Optionally by means of a FUHR radio access system e.g. transponder
• Optionally by means of another access system (release signal via potential-free contact)
• Optionally by means of a contemporary BMS device (Building Management System)
Do not operate the lever-handle during the electrical locking and unlocking procedure!
The optional ServoAccess version:
In addition to the standard functions above, ServoAccess provides an additional operation comfort due to a motorized sup-
port when opening mechanically. The multitronic 881 ServoAccess is opened from its locked basic position by the first key
turn. As a further benefit, the servo function supports the already smooth opening when the lever handle is operated slowly.
This function is particularly suitable for applications where the mechanical opening is done by key e.g.:
• In multi-family houses, where the operation of the access control is reserved for the owner for various reasons
• Office buildings in which only a time switch controls the activation and outside the „main times“ the key (locking system)
should be used
• For groups of people who for various reasons do not use access control, e.g. small children or elderly people who prefer the
conventional key for door opening
Further electrical connections are available for: (some are only operated by controler)

• Access control systems
• Electrically operated door openers

function, via cable or radio activation)

2 Important information/safety instructions
These instructions are aimed at door fabricators and contain important information regarding installation, commissioning and
operation pertaining to the FUHR multipoint locking system multitronic 881. Please read carefully prior to installation and com-
missioning. The points raised here provide supplementary information to the FUHR Product Liability Information for door locks,
see www.fuhr.de. In the event of non-compliance with these imperative instructions, faultless system operation cannot be war-
ranted. We assume that the installation as well as commissioning and maintenance is carried out exclusively by professional staff.
The FUHR multipoint locking system multitronic 881 has been designed and manufactured taking safety-related regulations
and harmonised standards into account. This product’s safety features are an essential pre-requisite for the EN 14846 accredita-
tion. Therefore no alterations or modifications may be carried out other than those described in these instructions.
The safety of the FUHR multitronic product largely depends on its correct installation and regular mainte-
nance! The installation of the electronic components requires particular care, since abrasion points, defective
cables, damaged contacts, etc. affect security and can lead to the malfunction of the system. Please ensure
that all components are in perfect functioning condition prior to installation. Damaged or defective compo-
nents may not be used under any circumstances. Use the locking system only in technically perfect condition!
Malfunctions that impair security are to be eliminated immediately. Until the malfunction has been elimina-
ted, the drive unit is to be switched off and operated mechanically! The power supply unit’s power feed is to
be disconnected when working on the locking system and live components.
The FUHR multipoint locking system multitronic 881 has been engineered to be used in conjunction with the provided FUHR
multitronic components. All specified components must be installed to ensure the requirements outlined in EN 14846 are met.
We accept no liability for improperly installed systems and/or the use of non-original or non factory approved system accessory
parts. The modification of components or the use of non approved accessory components can cause malfunctions. Material
damage or personal injury resulting from non-compliance with the installation, operation and maintenance instructions or inap-
propriate operation invalidates the warranty. We assume no liability for any consequential damage.
The FUHR multipoint locking system multitronic 881 must be protected from humidity. It is not suitable for
areas with high humidity and chemical substances.
The FUHR multipoint locking system multitronic 881 has been primarily designed for installation in main entrance doors, apart-
ment doors and back doors. Products manufactured in accordance with EN 14846 requirements provide a high level of personal
protection and adequate protection against intrusion when fitted to a suitable door and door frame. The system with 2 hook
bolts (type 3) has been tested and certified in accordance with DIN EN 179. The variants with 2 round bolts (type 8) and with
2 hook and dual round bolts (type 11) have been tested and certified in accordance with DIN EN 1125. For this purpose durability
testing in the highest grade (grade 7) with 200,000 operations was carried out successfully. The product was tested, approved
and certified for fire resistance on a single leaf aluminium door by MPA Braunschweig (certification number PB 3019/2006).
For use in heavily frequented doors (more than 50 operations per day) e.g. in public or office building projects,
it is necessary to use either of the two day-latch functions during busy periods (refer to chapter 6.1.4).
Do not operate the lever-handle during the electrical locking and unlocking procedure!
The installation steps depicted on the following pages serve as a schematic diagram. Due to the numerous profiles available on
the market, there may be slight deviations in specific points. It is therefore imperative that the profile-related routing drawing
provided with the FUHR multitronic set is adhered to. Please contact your sales partner or the manufacturer in the event of
discrepancies or queries. The indicated sequence in these installation instructions is exemplary. The sequence may be varied if
required.
IMPORTANT!
All components contained in the set (particularly the control unit and the radio key) are coordinated and should not be
used in conjunction with other sets.
