Schlage PM480 ATHA 626 – Frequently Asked Questions

1) How does the Schlage PM480 storeroom function actually work day to day?
The PM480 keeps the outside lever fixed at all times, so nobody gets in from the corridor side without a key. A key outside retracts both the deadbolt and the latchbolt, but the outside lever stays locked. Inside there is a thumbturn for the 1 inch throw deadbolt, and turning the inside lever pulls both the deadbolt and latchbolt back in one motion, so egress is always immediate. That combination is what you want on a storage room, mechanical room, or back-of-house door where the door has to stay secure but you cannot trap anyone inside.
2) What door thickness will a Schlage PM480 mortise lock fit?
Standard is 1-3/4 inch, which is the usual commercial door. It will go down to 1-3/8 inch minimum, and it will fit doors up to 2-1/2 inch thick, but for anything over 1-3/4 you have to specify the door thickness and the position of the lock in the door when you order, and that is available EE only.
3) Do I need to order the Schlage PM480 handed?
No. The PM480 is field reversible, so one lock covers left or right hand openings and you set it on site. That is worth knowing if you are buying for a building with mixed swings, because you can stock one part number instead of two.
4) What cylinder do I have to specify when ordering a Schlage PM480?
Cylinder choice is a required selection, with five options: P for a conventional 6-pin cylinder keyed 5-pin, L for less conventional 6-pin cylinder, J for less FSIC, B for less SFIC, and T for an FSIC construction core. If you already run an SFIC or FSIC key system in the building, order the less-core option and install your own cores. Pick P only if you want Schlage to supply the cylinder.
5) Can I make the PM480 match the other locks in my building?
The PM Series is made to suite with other Allegion products, and it shares lever and rose styles with the Schlage PT Series tubular locks, so mortise openings and tubular openings can look identical down the corridor. Ten lever designs are offered (Athens, Broadway, Latitude, Longitude, Neptune, Playa, Rhodes, Selena, Tubular and Two), with A, C or D rose or the N escutcheon, in six finishes: 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome and 643E aged bronze.
6) What is a Grade 1 storeroom mortise lock equivalent to the Schlage PM480 from another manufacturer?
The closest straight equivalents are the Accentra 8805FL Grade 1 storeroom mortise lock from the 8800 Series, and the Cal-Royal NM8080 Grade 1 storeroom mortise lockset, which offers an interchangeable core option. Both match the PM480 on Grade 1 rating and storeroom function. The difference to check is the deadbolt: the PM480 is a storeroom lock with deadbolt, with a key cylinder outside and thumbturn inside operating a 1 inch throw stainless steel deadbolt alongside the latchbolt. If your opening only needs the fixed outside lever and key-retracted latch without the auxiliary deadbolt, the 8805FL or NM8080 covers it; if the deadbolt is part of the spec, the PM480 function is the one to hold.
7) I need a mortise lock for a classroom door, not a storeroom. What should I use instead of the PM480?
The PM480 is a storeroom function - the outside lever is always fixed and can only be unlocked by key, which is not what a classroom opening calls for. For classroom function in a Grade 1 mortise, look at the Corbin Russwin ML2003 Grade 1 classroom mortise lockset from the ML2000 Series, or the Cal-Royal NM8070 Grade 1 classroom mortise lockset with auxiliary deadlatch. Both are listed for 1-3/4 inch doors, the same standard door thickness the PM480 is built around.
8) Does a Baldwin 6310 mortise lock fit the same prep as the Schlage PM480?
No - the backsets differ. The Baldwin 6310 entry/storeroom mortise lock body is a 2-1/2 inch backset unit, listed for doors 1-3/8 inch and over, and the lever-by-lever version is the 6310190RRLS in right hand reverse. The PM480 is 2-3/4 inch backset only and is field reversible for handing. A 2-1/2 inch backset lock will not drop into a pocket cut for 2-3/4 inch without re-prepping the door and the strike location.
9) Is the PM480 rated heavy enough for a high traffic commercial opening?
It is a Grade 1 commercial mortise lock. The case is cold rolled steel with corrosion resistant zinc dichromate plating, and both the deadbolt and latchbolt are stainless steel. That is the level you want on retail, multifamily, hospitality and institutional back-of-house doors rather than a residential-duty lockset.
10) Is the PM480 thumbturn ADA qualified?
The thumbturn style used on the PM480 is ADA qualified, and the trim is lever handle rather than knob. If your accessibility spec calls for operation without tight grasping or wrist twisting on both the latch and the deadbolt, that is the combination it gives you.
11) Is the Schlage PM480 an electronic or access control lock?
No, the PM480 is purely mechanical, keyed outside with a thumbturn inside. If you need credential or keypad access on a mortise prep, look at electronic mortise locks instead, such as the Schlage Electronics LEMD-GRW Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader, or the TownSteel FME-2000 Series Grade 1 RFID mortise lockset for 1-3/4 inch doors. The PM Series itself does include three electrified functions, but the PM480 is not one of them.
12) How much room do I need between the lever and the cylinder when laying out the PM480 on the door?
Spacing is 3-7/8 inch (98 mm) from lever to cylinder and 2-11/16 inch (68 mm) from lever to thumbturn hub. Use those with the 2-3/4 inch backset when you are checking clearance against a vision lite, a glass stop, or a narrow stile before you cut.
13) What mortise lock should I order if the door needs an office or entrance function rather than storeroom?
The PM480 keeps the outside lever locked at all times, with entry by key only, so it will not work where staff need to leave the door in a passage state during business hours. For office or entrance function in a Grade 1 mortise on a 1-3/4 inch door, the Cal-Royal NM8050 is an office/entrance mortise lockset with auxiliary deadlatch, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon at 2-3/4 inch backset - the same backset the PM480 uses - and is non-keyed.
14) Is the Sargent 7925 a substitute for the Schlage PM480?
They are both Grade 1 mortise locks with a deadbolt, but the functions differ. The Sargent 7925 from the 7900 Series is a dormitory exit function lock with rose trim and a single cylinder deadbolt. The PM480 is storeroom with deadbolt: the outside lever is always fixed, key outside retracts both deadbolt and latchbolt while the outside lever stays locked, and the inside lever retracts both for immediate egress. Confirm which function the door schedule calls out before swapping one for the other - dormitory and storeroom behave differently on the outside lever.
15) What is the electronic alternative if I want keypad or credential access on a storeroom opening instead of the keyed PM480?
The PM480 is a mechanical keyed lock with no electronics. For credential or code access in a mortise prep, the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125 kHz proximity reader and mobile-enabled deadbolt with LED, rated 3 hours fire. The Command Access ML190 Series is a heavy-duty motorized mortise lock with storeroom function and field-selectable fail-safe or fail-secure operation on 24VDC, which matches the PM480 function while adding access control. Electronic units bring power, wiring or battery service into the job that the PM480 does not require.
16) I need a mortise lock for a behavioral health or ligature-resistant opening. Is the PM480 appropriate?
The PM480 uses conventional lever trim in ten lever designs with A, C and D roses or an N escutcheon, which is standard commercial trim rather than ligature-resistant. For those openings, the TownSteel MRX-L-01 is a Grade 1 heavy-duty anti-ligature lever mortise lockset in stainless steel with passage function, the MRX-A-01 is the same in a ligature-resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant. Note those three are passage function, not the keyed storeroom function the PM480 provides.
17) What do I order if the opening needs a privacy mortise lock instead of the keyed PM480?
The PM480 is keyed with a cylinder outside, which is not a privacy arrangement. For privacy in a Grade 1 mortise, the Cal-Royal NM8440 is a heavy-duty Grade 1 privacy mortise lockset with deadbolt on 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with 2-3/4 inch backset, the same backset as the PM480, listed for doors 1-3/4 inch to 2 inch.
18) Will an Alarm Lock Trilogy mortise lock fit the same doors as the PM480?
Check the door thickness first. The Alarm Lock DL2700CR and DL3500CR Trilogy electronic mortise locks are Grade 1 classroom function units listed for doors 1-5/8 inch to 1-7/8 inch, and the DL4500 Series Grade 1 electronic mortise deadbolt carries the same 1-5/8 inch to 1-7/8 inch range. The PM480 is standard at 1-3/4 inch, with a 1-3/8 inch minimum and fits doors up to 2-1/2 inch thick when the thickness and position in door are specified. On thin or thick doors outside that 1-5/8 to 1-7/8 window, the PM480 covers openings the Trilogy units do not.
19) For an aluminum storefront or glass door, is the PM480 the right mortise lock?
Generally no. The PM480 is built around a 4-7/16 by 6-1/16 by 1 inch case at 2-3/4 inch backset in a 1-3/4 inch door, which is a standard wood or hollow metal commercial prep. Narrow and glass openings take different hardware: the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock is made for Adams Rite deadlatches, the Dormakaba E-Plex 2066 is a wide stile electronic pushbutton mortise lock, and the Kaba Ilco BR Series is a glass door bottom rail lock. Match the lock to the stile and rail before specifying.
20) I want a classroom security or intruder function mortise lock rather than a storeroom lock. What are my options?
The PM480 is storeroom function - lockdown from inside is not part of how it works, since the outside lever is always fixed and keyed. For lockdown-capable openings, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with an ANSI strike and an 8-1/2 by 2-3/4 by 7/16 inch steel escutcheon on 1-3/4 inch doors, the BEST 45HCA lockbody is offered in intruder function, and the TownSteel FME-4000 Series is an electronic intruder classroom mortise lockset with RFID, Grade 1 heavy duty on 1-3/4 inch doors.
21) I need classroom or office function instead of storeroom. Does the PM Series cover that?
The PM Series offers 26 functions in total, including four mortise deadbolt functions, so classroom and office variants exist within the same series and share the same trim and finishes. If you are cross-shopping other brands for those functions, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, and the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch.
22) Is a BEST 45H mortise lock body a drop-in for the PM480?
Treat them as different locks. The BEST 45H Series is a heavy-duty mortise lock body in public entrance function with field reversible operation, and the 45HCA Series lockbody is offered in intruder function. The PM480 is storeroom with deadbolt and is also field reversible, but Schlage notes that PM and L Series case and cover holes differ, so case and trim hole patterns should be confirmed against the template before assuming any mortise body interchanges with another maker's trim.
23) If I do not need a lock at all on some of the doors, what matches the PM480 trim on a passage opening?
For passage openings in the same Grade 1 mortise class, the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating, and the Hager 3810S and 3810E are Grade 1 passage mortise locks at 2-3/4 inch backset in rose and escutcheon trim respectively, for doors 1-3/4 inch to 2-1/2 inch. The PM480 shares the 2-3/4 inch backset and is offered with A, C and D roses or an N escutcheon, so the rose-versus-escutcheon choice runs the same way across the opening.
24) Are the Emtek mortise entrance locksets an alternative to the Schlage PM480?
No. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are dummy function - they mount trim and do not latch or lock. The PM480 is a commercial keyed storeroom lock with a working latchbolt, deadbolt and deadlocking auxiliary latch. Dummy sets are for inactive leaves and closet doors only.
25) Can I order just a thumbturn like the Sargent 130KB instead of the whole PM480?
Those are not interchangeable parts. The Sargent 130KB is a standard mortise thumbturn for the 8200 Series and the 130W is a mortise thumbturn with a round backplate for the 7800 Series - trim components for those lock bodies. The PM480 ships as a complete keyed storeroom mortise lock with its own ADA-qualified thumbturn style, lever trim and an ANSI curved lip strike with dust box. Order thumbturns against the lock series they are built for.
