Offering a practical hybrid solution for multiple occupancy buildings, or dwellings which require the security and convenience of an automatic lock and the advanced functionality of an electromechanical lock with access control options.
On closing the door, two latching deadbolts simultaneously extend and lock in place providing additional security compared to a standard mechanical door lock as the user doesn’t need to remember to secure the door. Unlocking the door is motorised allowing access control to be added or for integration into existing building management systems.
The lock is available with or without panic/emergency exit functionality depending on the project requirements.
Operation:
Emergency Exit & Panic Doors (834P):
Available for single and double doors providing all of the benefits of the standard 834 lock while allowing unimpeded escape from the inside using the lever or panic push bar at any time and on either the active or inactive door leaf.
The hardware meets the British Standard requirements when used alongside the recommended FUHR lever handle (EN 179 for emergency escape) or Panic Bar (EN 1125 for panic exit) and the CES free movement cylinder.
PAS 24 is an enhanced security performance test for door assembly requirements, every component used within the door set tested must comply to the relevant British Standard for that component.
PAS 24 includes several security tests, such as:
An example of the intensity of the testing, the mechanical loading tests subjects the door set to 4.5Kn of pressure, the equivalent of approximately 45 times the pressure used to tighten a car wheel nut.
Backset
The backset is the dimension from the front of the faceplate to the centre of the handle spindle or cylinder hole.
The most popular backset sizes are 25mm, 30mm, 35mm and 45mm.
The backset dimension is the distance between A and B on the diagram.
PZ Centre
The "PZ" or "Centre" is the distance between the centre of the handle spindle and the centre of the round section of the cylinder.
The PZ Centre dimension is the dimension between C and D on the diagram.
Multipoint locks can have one or two spindle holes (also known as followers) these type of locks will have two measurements, the most popular being 62mm / 92mm.
Most modern locks with one spindle are 92mm centre, however some older locks may be 70mm or 72mm.
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.
Step 1 Unscrew and remove the 3 screws as shown in the video
Step 2 Remove the lockcase
Step 3 Clip the replacement lockcase in place
Step 4 Replace the 3 screws
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.
Step 1 Remove the magnet from the frame
Step 2 Close the door until the tappets on the hinge side touch the contact plate (don't fully close the door)
Step 3 Place the magnet against the small circule within the magnet part of the door lock
Step 4 If the hook locking points extend, then the lock is working correctly.
