Functions and interfaces of this model
This older model uses an inside button and separate outside cylinder, with a self-locking latch and integrated loading spring. When finding a replacement, check supply, strike plate and outside-cylinder interface rather than comparing only case width.
Using backset for compatibility checks
The catalogue records this model's backset as 80 mm. Backset is measured from the specified faceplate or door-edge reference to the operating centre. It describes a different direction from centre distance, lock-body width and door thickness; retain the original drawing's reference when measuring.
The selection checklist should also retain: backset 80 mm; Rated supply 12 V AC; Power 15 W; Inside operation Push-button; Outside cylinder Separate; Handing Non-handed; Catalogue status Discontinued (red square in the catalogue). Even for models with the same backset, compare handing, latch/bolt configuration and drive interfaces.
Checks before replacement and installation
Give the supplier the full model number 511800, photographs of the original lock body, door handing and measured dimensions. The measurement reference in the diagram only explains what the dimension means; it cannot be used directly as a drilling template.
For electric configurations, also check power-supply and control requirements; for mechanical versions, check the strike plate, cylinder connection and range of movement.
Limitations
- The original catalogue marks this model as discontinued; this record supports old-lock identification and replacement-document checks; this is not a statement of current availability.
- This page follows the specific model row in Catalogue .42; it does not replace site installation drawings or the manufacturer's confirmation of current supply.
- The measurement diagram explains only this page's dimensional reference; it does not show the product appearance, drilling positions or complete installation dimensions.
