PDQ SV115 CQ Grade 2 Storeroom Knob Lockset - ANSI F86 Security Solution

Function Information:

• Latchbolt operated by inside lever or key in outside lever.
• Outside lever always fixed
• Deadlocking (guarded) latchbolt
• ANSI F86 

The PDQ SV115 CQ is an industrial-grade Grade 2 Storeroom Function Knob Lockset engineered for high-security areas that must remain locked at all times from the exterior. Designed for utility closets, mechanical rooms, and storage areas, this lockset ensures that the outside knob is always fixed, preventing unauthorized entry by mistake or oversight. The Storeroom Function (ANSI F86) is a critical security solution for facility managers who need to guarantee a "lock-on-close" protocol without relying on a user to manually turn a thumbturn or throw a deadbolt.

Built to exceed ANSI/BHMA Grade 2 standards, the SV Series features a heavy-duty cylindrical chassis and a deadlocking guarded latchbolt that resists shimming and "loiding" attacks. This lockset is supplied with a standard 2-3/4" backset and a heavy-duty 4-7/8" ASA strike, making it an ideal retrofit solution for hollow metal doors in schools, retail back-of-house areas, and multi-family housing complexes. The CQ (Ball Knob) design offers a classic, rugged aesthetic while providing the tactile grip necessary for high-frequency utility use.

ANSI F86 Storeroom Function: Fail-Safe Perimeter Security

The ANSI F86 Storeroom Function is specifically designed for rooms where entry should be restricted to key-holders only, while egress is always unrestricted.

• Always Locked Exterior: The exterior knob is permanently rigid. Entry is only possible by inserting and turning a key. This eliminates the risk of a room being left accidentally unlocked.
• Unrestricted Egress: The interior knob always allows for immediate exit. Turning the inside knob retracts the latchbolt instantly, satisfying all Life Safety and Fire Codes.
• Automatic Re-locking: Because the outside knob is fixed, the door is effectively "re-locked" the moment it latches into the strike. There is no "unlocked" mode for the exterior.
• Guarded Latchbolt: The lock features a deadlocking (guarded) latchbolt. When the door is closed, a small auxiliary pin is depressed, mechanically deadlocking the main latch to prevent it from being pushed back with a credit card or shimming tool.

Engineered Solutions for Storage & Utility Access

The PDQ SV115 CQ addresses the specific operational and security challenges of commercial facility management:

• Human Error Mitigation: In busy environments like hospitals or schools, staff often forget to lock storage rooms containing sensitive equipment or hazardous materials. This lockset is the primary solution for ensuring those doors are never left vulnerable.
• Simplified Retrofit Capability: With the standard 4-7/8" ASA strike and 2-3/4" backset, this unit is a direct replacement for most commercial cylindrical locks. It allows for a fast security upgrade without the need for door or frame modifications.
• Vandal Resistance: The cylindrical chassis is designed to withstand higher torque loads than standard residential hardware, ensuring the lock remains functional even in high-traffic or abusive environments.
• Keying System Integration: Equipped with a standard Schlage C compatible keyway, the SV115 can be easily integrated into existing master key systems, allowing facility managers to use one key for multiple doors across the property.
• Fire Safety Compliance: This lockset is designed for use on fire-rated doors, ensuring that storage rooms act as effective fire barriers by remaining closed and latched when not in use.
