Commercial High Security Cylinder System

Key Control Hardware

Primus answers the issue vital to maintaining security, the elimination of key duplication. A patented "dual-locking" feature is tailored to suit your particular needs. The Primus key, with side-bit milling along the key blade, is designed to operate both standard as well as Primus keyways. A standard Schlage section key cannot enter the unique Primus cylinder. Only authorized Schlage Primus dealers can duplicate the key for the end-user designated with a Primus identification card.

Five security levels are differentiated by increasingly restrictive key availability, more selective signature verifications and side-bit milling combinations. The Primus system is compatible with Schlage's full line of security locks, easily accommodating upgrades to existing Schlage keying systems.

Applications: Fine homes, multi-family housing, retail stores, office and commercial space, schools, universities, hospitals, industrial sites, and wherever key control and physical security are important concerns.

Certifications: 20-500 High Security cylinder: U.L. 437 Listed; ANSI A156.5, 1992, Grade 1.
20-700 Controlled Access cylinder: ANSI 156.5, 1992, Grade 1 Operational

Keying: Primus allows integration with existing standard Schlage key systems by utilizing a Primus key to operate both Primus cylinders as well as Schlage standard pin tumbler cylinders. Primus cylinders may be master or grandmaster keyed. Primus keys can be cut to operate all cylinders, while standard keys will not even enter Primus cylinders. In addition, 20-700 Controlled Access cylinders are available in Schlage's family of interchangeable core cylinders.

Product Compatibility: Primus cylinders can be used with: A, AL, B, C/D, E/B, H, L, S and S200-Series locks. Mortise, rim cylinder, PL-Series padlocks, CL-Series cabinet locks, and interchangeable core versions are also available.

The side-bit milling operates the second locking mechanism and can be thought of as a unique "fingerprint" of the key.

Primus cylinders are offered in two different versions. The 20-500 High Security series which is U.L. 437 Listed and the 20-700 Controlled Access series which offers the same key control protection when U.L. 437 Listed cylinders are not necessary. Both series are fully compatible in application and can be combined into the same masterkey system, along with Schlage standard cylinders. For added flexibility, all Primus cylinders can be retrofitted into existing Schlage locks as well as many competitive products.
