ANSI F109: The Two-Mode Push-Turn Button Explained

The 5407LN function is ANSI F109 - entrance or corridor with push-turn inside button. Every competitor page lists this function without explaining it. The button does two completely different things depending on how you use it, and the difference matters operationally.

Mode 1 - Push only (auto-release): Push the button straight in. The outside lever locks immediately - it can no longer retract the latch from outside. This mode is self-releasing. The outside lever unlocks automatically when either the inside lever is turned or a key is used from outside. This is the quick-lock mode used when a teacher, office manager, or security staff member needs to restrict entry temporarily - push the button, the door is locked, and it releases automatically when the next authorized person uses a key. No manual reset required.

Mode 2 - Push and rotate 90 degrees (sustained lock): Push the button in, then rotate it 90 degrees clockwise to the horizontal position. Now the lock stays locked even after the inside lever is turned. It remains locked until someone physically returns the button to the vertical position. This is the sustained lockdown mode - correct for offices, storerooms, or any space where the room needs to stay locked through multiple inside exits without someone holding or resetting the button each time.

The inside lever is always active in both modes. The inside occupant can always exit freely regardless of button state.

5407 Part Number Specifications: Full Model String Decoded

If you searched "5407 part number specifications" or "part number 5407 specifications" - the 5407LN model string encodes the lever style, cylinder format, and finish in a structured prefix/suffix system. Here is the complete decode:

Lever prefix: AU = Augusta, MO = Monroe, PB = Pacific Beach

Cylinder format suffix:

• No suffix = standard conventional cylinder with keyed core (6-pin, keyed different, 2 keys included)

• LC = less cylinder (lockset body only, no cylinder - for facilities keying in the field)

• SC-KD = Schlage C keyway, keyed different (for buildings running Schlage key systems)

• B = SFIC prep (Small Format Interchangeable Core, less core - for BEST-format IC systems)

• ICLC = LFIC less core (Large Format Interchangeable Core, for Yale/Schlage LFIC systems)

Finish suffix: 626 (satin chrome), 613E (oil rubbed bronze), 605 (bright brass), 606 (satin brass), 625 (bright chrome), and others.

A full model number example: AU5407LN-ICLC-626 is the Augusta lever, LFIC less core, satin chrome. MO5407LN-SC-KD-626 is the Monroe lever, Schlage C keyway keyed different, satin chrome. B-AU5407LN-626 is the Augusta lever, SFIC prep, satin chrome.

5407LN vs Other 5400LN Functions

The 5400LN platform covers multiple ANSI functions, and the 5407LN is the entrance/corridor specification. Here's how it differs from the most commonly compared functions:

5405LN (ANSI F86, storeroom) - outside lever always requires a key. The inside button does not exist. The occupant inside cannot lock or unlock from inside - the door always requires a key from outside. Correct for server rooms, supply closets, and storage areas.

5408LN (ANSI F84, classroom) - key from outside toggles locked/unlocked. Inside always free. No auto-lock by inside button. The occupant cannot control the locked state from inside.

5407LN (ANSI F109, entrance) - inside push-turn button controls the outside lever. Either auto-release push or sustained-lock push-and-rotate. Key from outside always works. Inside always free. This is the most versatile office and corridor function - it gives the inside occupant active control over access without requiring a key.

Yale Cylindrical Lockset: The 5400LN Heavy-Duty Platform

The 5400LN is Yale's Grade 1 institutional cylindrical lever line, built for high-traffic commercial, educational, healthcare, and government applications. The construction features that distinguish it from Grade 2 locks are the same across all 5400LN functions: wear-resistant chassis plates at internal contact points, thread-locking thrubolts that resist backing out from door slam vibration, heavy-duty lever return springs under lifetime warranty, and a stainless steel deadlocking latchbolt. Bore hole is 2-1/8 inches. Backset is 2-3/4 inches standard, with 2-3/8 and 3-3/4 inches available. Door thickness is 1-3/4 to 2 inches standard. Three lever styles - Augusta (AU), Monroe (MO), Pacific Beach (PB) - all non-handed and ADA compliant.
