Schlage ND80EU Storeroom Lock — Electrically Unlocked Fail Secure with Request to Exit

Schlage ND80EU — Fail-Secure Storeroom Lock, Electrically Unlocked with Request to Exit (RX)

The Schlage ND80EU is a Grade 1 cylindrical storeroom lever lock with electrified fail-secure (electrically unlocked) operation and integrated Request to Exit (RX) function. The outside lever remains continuously locked until released by key or electric current — when power is removed, the lock stays locked, making it the correct choice for high-security storerooms, server rooms, pharmacies, and controlled-access areas where security must be maintained during a power failure. The inside lever is always free for immediate egress.

Schlage ND Series Overview

The Schlage ND Series offers a full breadth of commercial lock options with a suited combination of mechanical, electrified, and electronic options. Beyond Grade 1 performance is the hallmark of the mechanical and electrified locks. ND Series locks are tested to withstand 3,100 in-lb. of abusive lever torque — more than 2.5 times the Grade 1 standard requirement. Offset lever pull testing up to 1,600 lbs. assures superb resistance against pry bar attacks. Built to last, ND Series shows nearly zero droop or wobble after 16 million cycles.

All ND Series locks use the common cylindrical ANSI 161 door preparation, making them easily interchangeable and ideal for new construction and retrofit applications.

Features & Benefits

Security

• Significantly exceeds ANSI/BHMA Grade 1 requirements
• No access with minimum 3,100 in-lb. abusive lever torque (2.6x BHMA requirement)
• No access with minimum 1,600 lbs. offset lever pull — protection against pry bar attacks (8x BHMA requirement)
• 5 points of engagement — nearly zero droop and wobble after 16 million cycles (16x BHMA requirement), without set screws or O-rings
• High security locking when used with Primus XP UL 437 listed cylinders

Function Availability & Convenience

• 24 mechanical / 4 electrified functions in the ND Series (custom functions available upon request)
• Multiple key systems available: open, patented, and restricted
• Four electrified functions auto-detect 12/24V DC operation; maximum 0.4A draw, 0.1A holding current — eliminates heated levers
• Indicator roses available for classroom applications
• Three spring cage sets support all Schlage plus eight competitive cylinder formats

Aesthetics

• Nine lever and four rose designs
• Ten available finishes
• Suites with Von Duprin exit devices and other Schlage products

Options

• Vandlgard™ models feature a lever that freely rotates when locked to protect the chassis from excessive force and prevent vandalism

_{*Beyond Grade 1 performance for ND Series locks with Schlage cylinders only (Conventional, FSIC & SFIC). Performance with non-Schlage cylinders will exceed BHMA Grade 1 requirements, but may be less than that of Schlage cylinders.}
