The FUHR 871 emergency exit multipoint door lock features 2 steel round bolts, latch and deadbolt. The door lock is capable of meeting the requirements of EN 1125 (applies to public buildings or other premises where occupants may not be familiar with exit routes and hardware devices) and EN 179 (applies to non-public buildings and potentials users have been fully trained on how to use the door).
In order to comply with these standards, the lock must be used with an approved free movement cylinder and panic bar.
The 871, when unlocked at the cylinder, allows entry by means of the lever from the outside. In order to fully secure the door from the outside the door must be locked. Access from the inside is always available. This is ideal for emergency exit doors which are in regular use during the day, but need to be secured at night.
There are more handle options with the FUHR 871, including a specific lever / lever, the internal lever can be replaced with a push bar or lever (this will only achieve EN 179 for non-public buildings and potentials users have been fully trained on how to use the door). For handing purposes the FUHR 871 is always viewed from the outside.
Throw
A Eurogroove is an industry standard feature on most PVCu, aluminium and timber door and window profiles, where the locking devices are fitted.
A Eurogroove is the groove in the profile in which multipoint locks and espagnolettes are fitted. This is always 16mm for PVC, but can be 20mm in Timber.
A free movement cylinder allows a key to operate the cylinder even when there is already a key inserted in the other end. These cylinders are for use on emergency exit door lock kits such as the FUHR 870 and 871. This function ensures that when the panic bar or panic lever is pushed the cam will rotate freely and allow use at any time.
This type of cylinder is also recommended for use with the FUHR 881 Electromechanical Door Lock.
On most FUHR locks, to change the handing you remove the small grub screw on the side of the lock case adjacent to the latch plate with a 2mm allen key.
Remove the latch and turn in it 180º vertically, place it back into the opening and secure the grub screw back in place.
The FUHR 871 and FUHR 881 door locks are supplied handed, this cannot be changed, so please ensure you order the correct handing for the application.

Hook and Keep alignment:
The hook and keep should be aligned using the guideline on the hook plate. Ensure the hook engages correctly avoiding friction on which can result in damage to the hook, there should be a 2mm gap between the line on the hook plate and the flat of the hook as shown in the diagram.
Latch and hook adjustment:
Take care not to over adjust the hook keep as this can damage the keep - do not rotate through 360º. A screwdriver and a 4mm allen key will be required when adjusting these plates.
Roller and mushroom adjustment:
Adjust eccentric compression of roller and mushroom keeps to ensure the optimum compression for the door. Adjust the compression using a 4mm allen key.
