Schlage CYLINDERS - Manual (Page 6)

Performance Features
The Schlage Primus High Security cylinder is precision built to extremely close tolerances and the highest standards of quality.
These “dual-locking” cylinders consist of two independent locking mechanisms operated by a single, specially designed
Primus key. In addition to a standard 6-pin mechanism there is a locking sidebar which is independently controlled by a set of
five finger pins that interface with the side bitting on the patented Primus key. Each finger pin must be lifted and swiveled to
the right orientation.
Primus cylinders are offered in two different versions. The 20-500 High Security series is UL Listed and the 20-700 Controlled
Access series offers the same key control and pick resistance when UL Listed cylinders are not necessary. Both series can be
combined into the same master key system, along with Schlage conventional cylinders. For added flexibility, all Primus cylinders
can be retrofitted into existing Schlage locks as well as many other manufacturers’ products.
Flexibility
Unlike many other brands of high security cylinders, Schlage can easily integrate Primus UL437 Listed cylinders, Primus Controlled
Access cylinders, and Schlage conventional cylinders all into the same key system, and this happens with no adverse affects on
keying capacity!
Primus keys will operate conventional cylinders but conventional keys will not operate Primus cylinders. You can secure
exterior doors and sensitive areas with Primus cylinders and use conventional cylinders on the remaining doors. This cuts the
cost of the overall job.
Security can be tailored to meet the exact needs of each door without sacrificing the convenience of having a single building
master key.
