Digital Door Locks

 200 Series
Combination Lock
SIMPLEX NL200

This lock is suitable for use as a light-to-medium duty lock for internal low-security doors. Access is gained by entering the correct combination that allows the outside thumbturn to open the door. From the inside, the thumbturn will always retract the bolt allowing constant easy exit from the protected area. A holdback facility allows the door to be left unlocked for ease of use (i.e. when carrying a large number of items through the door). It should be noted however, that the cast ‘Mazak’ lock casing is not weather resistant and will not withstand a forced physical attack.

Installation:

The NL200 lock is as easy to install as a cylinder nightlatch ( Yale type lock ). The only non-standard tool required is a 43mm hole saw. The lock can be fitted to doors of 44mm – 54mm thick. The physical size of this lock means that it is necessary to have a door stile width of between 100mm and 110mm. This can make it virtually impossible to fit to many narrow stile timber and metal doors. If you wish to fit a mechanical digital lock to a door of less than this size, check the details of the Simplex 3000.

As the main reason for fitting digital locks is access control, it will be necessary to fit a door closer to ensure the door closes behind the user, as it cannot be assumed that everyone will close the door behind them. A DL200 (deadlock version) is also available, and for the above reason we do not recommend the use of the DL series on personnel doors. When fitting, ensure that the door does not slam and that the latch enters the strike correctly. Clean and lubricate the lock with WD40 or similar as ordinary oil attracts dirt and will eventually damage the lock.
