The FUHR multipoint locking system multitronic 881 has been designed and manufactured taking safety-related regulations and
harmonised standards into account.
The safety of the FUHR multitronic product largely depends on its correct installation and regular
maintenance! 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
components 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 eliminated, 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. 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 inappropriate 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,
apartment doors and back doors. 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.
When using in heavily frequented doors (more than 50 operations per day) e.g. in public or office building pro-
jects, it is necessary to use either of the two day-latch functions during busy periods (refer chapter 6.1).
