PDQ MR259 PFSF Dormitory w/Indicator (F33*) Function Mortise Lockset - Grade 1

The PDQ MR259 PHL (often ordered as PFSF for the Philadelphia lever on an F-Series Sectional (round rose, wrought trim)) is a premier Grade 1 Dormitory w/Indicator (F33*) Function Mortise Lockset engineered for demanding commercial environments. While typical commercial locks are rated for one million cycles, the PDQ MR Series is tested to over 11 million cycles -- extending the hardware lifespan by 11 times the industry standard. It serves dormitory and residential doors with an occupancy indicator and single-motion egress.
Constructed with a heavy-duty 12-gauge cold rolled steel mechanism and a 1-inch throw investment cast stainless steel deadbolt, the MR259 adds a occupancy indicator to the trusted MR function. The Philadelphia (PHL) lever offers a clean, architectural aesthetic in a US32D Satin Stainless finish. Its "return-to-door" design is not only ADA compliant but also prevents clothing, bags, or straps from snagging on the hardware in busy corridors.
ANSI Function F33 (w/Indicator): Dormitory w/Indicator (F33*)
The Dormitory w/Indicator function operates the latchbolt from either side, throws a deadbolt by key from either side, gives single-motion inside egress, and shows a VACANT/OCCUPIED status on the inside:
- Latchbolt operated by lever from either side.
- Key outside extends/retracts deadbolt.
- Key inside extends/retracts deadbolt.
- Inside lever simultaneously retracts latchbolt and deadbolt.
- Indicator, inside -- (VACANT/OCCUPIED).
Catalog note: The F33 Dormitory function is sometimes printed under the adjacent "Intruder Deadbolt" column label in the price book; the bullets and ANSI F33 identify this as the Dormitory w/Indicator function.
Finish availability: This indicator function is not offered in 626 (US26D Satin Chrome). The base finish is 630 (US32D Satin Stainless), with premium architectural finishes (605, 606, 612, 613E, 622, 629) also available.

Engineered Solutions for Commercial Security
The PDQ MR Series addresses the specific technical and safety challenges of modern facilities:
- Occupancy Indicator: The inside indicator window reads VACANT / OCCUPIED, which reduces accidental openings on restrooms, locker rooms, and single-occupancy spaces.
- Vandal-Resistant Spindle: The "weakened spindle" design is a critical security solution. If the exterior lever is subjected to extreme torque or a hammer attack, the spindle breaks cleanly to prevent damage to the internal 12-gauge steel case, keeping the lock secure.
- Extreme Weather Durability: Certified for High Velocity Hurricane Zones (HVHZ) with a design load rating of +/- 70.0 PSF, this lockset provides the structural integrity necessary for coastal buildings.
- Simplified Key Management: Provided with a Schlage C (SCC) compatible cylinder, the MR259 integrates easily into existing master key systems. It also supports Interchangeable Core (IC) options for rapid re-keying.
- Fire Safety Compliance: With a UL 3-hour fire rating, this lockset ensures that commercial doors remain a reliable fire and smoke barrier, protecting occupants and property.
