Alarm Lock PDL4500DBR US26D – Frequently Asked Questions

1) Will the Alarm Lock PDL4500 latch into the strike already in my frame?
A 1-1/4 by 4-7/8 inch strike ships with the PDL4500, which is the common ANSI-style mortise strike size, so in most commercial frames the existing prep is reused. The deadbolt is stainless steel with a 1 inch projection and the latchbolt throws 3/4 inch with a deadlocking latch, so the frame needs a deadbolt pocket deep enough for a full 1 inch bolt. If the existing frame has only a latch cutout and no bolt pocket, the frame gets drilled.
2) Do I have to specify handing on the Alarm Lock PDL4500, and can it be changed on site?
Handing gets specified at order time, right hand or left hand, and both are offered in US26D satin chrome. The lock is reversible in the field, so a mis-specified hand can be corrected on the job rather than returned.
3) What credentials does the Alarm Lock PDL4500 accept besides a keypad code?
Two ways in: the 12 button all metal weatherproof keypad, and an integrated proximity reader that reads 26 to 37 bit HID card and keyfob formats. If a building already issues HID prox cards in that bit range, the same badge works on this door. Capacity is 2,000 user codes with master, management, supervisor and basic levels, plus a 40,000 event audit trail and 500 event scheduling.
4) Does the Alarm Lock PDL4500 need to be wired to power or a panel?
No wiring. The PDL4500 runs on a 5AA alkaline battery-pak, included, rated at about 60,000 cycles of typical operation. It is a standalone lock, so there is no panel, no power transfer hinge, and no door loop to pull. That is the difference between this and a wired electromechanical mortise lock like the BEST 45HW, which runs on 12V or 24V and needs power brought to the door.
5) What mortise cylinder does the Alarm Lock PDL4500 take for key override?
A 1-3/8 inch mortise cylinder comes with the lock, and the body accepts a 1-3/8 to 1-1/2 inch mortise cylinder, so a facility standardizing on its own keyway can swap in a cylinder of either length. The deadbolt can be thrown from the key cylinder outside or the turn-piece inside. Keying is chosen when ordering: keyed different, keyed alike, or to a specific key code you supply.
6) Is the Alarm Lock PDL4500 Grade 1, and is it fire door rated?
Grade 1. The Steelcase lock body meets BHMA specifications for Grade 1 locks, and the lock is UL Listed to the 10C Positive Pressure Specification with ADA compliant levers. That combination is what an institutional spec usually calls for on a rated opening.
7) I need a deadbolt on the door, not just a latch. Which electronic mortise locks give me one?
The PDL4500 is a deadbolt function lock: stainless steel deadbolt with 1 inch projection plus a 3/4 inch deadlocking latchbolt, so you get both in one mortise body. Watch this when cross-shopping, because several standalone electronic mortise locks are latch only. The Accentra NTM623-NR nexTouch Generation 3, for example, is the no deadbolt version with cylinder override. If the requirement is a mechanical deadbolt with no electronics at all, the Sargent 4874 double cylinder mortise deadbolt runs the same 2-3/4 inch backset.
8) What is the closest equivalent to the Alarm Lock PDL4500 if I need a standalone electronic mortise lock with a proximity reader?
The Alarm Lock PDL4500 combines a 12-button metal keypad with proximity reading, so credentials can be presented as a card, keyfob, or code. Two peers work the same way. The Dormakaba E-Plex E5086 is a Grade 1 electronic pushbutton/card mortise lock in a back-to-back configuration, and the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and a mobile-enabled deadbolt. The LEMD-GRW ships as a right-hand unit with Greenwich trim and carries a 3 hour fire rating; the PDL4500 is offered in left hand and right hand and is reversible in the field. All three read credentials at the door rather than through a wired panel.
9) I do not need proximity cards, just a keypad. What electronic mortise lock should I look at instead of the PDL4500?
The Alarm Lock PDL4500 reads both keypad codes and proximity credentials. If codes alone will cover the opening, the BEST 45HZ EZ Series electronic keypad mortise lock adds a key override function, the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock built for wide stile doors, and the Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader in the privacy function for 1-3/4 inch doors. The Accentra NTM623-NR nexTouch Generation 3 is a Grade 1 mortise lock with a capacitive touchscreen keypad and cylinder override, with no deadbolt.
10) The opening has door position and access control wiring already run. Is the Alarm Lock PDL4500 the right choice or should I use a wired lock?
The Alarm Lock PDL4500 is battery operated, running on a 5AA battery-pak rated for about 60,000 cycles, and it stores its 2,000 user codes at the door rather than at a panel. For an opening with power already at the frame, the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation, the Command Access ML190 is a heavy-duty motorized mortise lock in the storeroom function with field selectable EL/EU operation on 24VDC, and the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, on 12/24VDC for 1-3/4 inch doors.
11) What Grade 1 electronic mortise locks are alternatives to the Alarm Lock PDL4500, and which electronic mortise locks are not Grade 1?
The Alarm Lock PDL4500 is Grade 1, and its Steelcase lock body meets BHMA specifications for Grade 1 locks with UL listing to the 10C Positive Pressure Specification. Grade 1 electronic peers include the Dormakaba E-Plex E5086, the Schlage CO-100 electronic mortise lock with keypad reader, the Schlage Electronics LEMD-GRW ENGAGE wireless mortise lock, and the TownSteel FME-2000 with RFID. Two electronic mortise locks sit below that: the Dormakaba Saffire LX-I-M002 RFID mortise lockset with BLE mobile access is BHMA Grade 2, and the Schlage Electronics LEBMB-ADD mobile-enabled mortise lock is Grade 2. The Codelocks CL2255 electronic tubular mortise latch is medium duty. For a facility standardizing on a Grade 1 spec, that distinction decides the submittal.
12) I want the deadbolt and privacy behavior of the Alarm Lock PDL4500 without any electronics. What mechanical lock does that?
The Alarm Lock PDL4500 pairs a deadbolt function with a privacy lockout controlled from inside the room. Mechanically, the Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch. For dormitory corridor use where the deadbolt is thrown from inside, the Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt. What the mechanical route gives up is credential management: the PDL4500 holds 2,000 user codes and reads HID card and keyfob formats.
13) Can I put an electronic keypad lock on an exterior or unheated door?
The PDL4500 is rated weatherproof and operates from -31F to +151F, with the keypad in all metal and the proximity antenna housing molded in impact resistant Lexan. That covers exterior entries, unconditioned stairwells, and parking structures. Many indoor-only electronic mortise locks will not hold up in that range.
14) What is the privacy pushbutton on the PDL4500 for, and how is it different from a classroom lock?
The privacy pushbutton locks out all users from inside the room for a programmed length of time, so codes and credentials at the keypad stop working until it releases. That is a lockdown from the inside, done without a key and without staff stepping into the corridor. A classroom security function lock such as the TownSteel FME-4000 electronic intruder classroom mortise lock is the alternative approach for the same problem. There is also a residency feature that lets someone exit without having to re-lock the door behind them.
15) What else could I use instead of the Alarm Lock PDL4500 for standalone keypad access on a mortise door?
Several standalone electronic mortise locks cover the same job differently. The Dormakaba E-Plex E5086 is a Grade 1 pushbutton and card mortise lock in a back to back configuration. The Dormakaba E-Plex 2066 is pushbutton only, no card reader, for openings where credentials are not needed. The BEST 45HZ EZ Series is an electronic keypad mortise lock with key override. For proximity credentials on a networked platform rather than a standalone lock, the Schlage LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and deadbolt. Note the PDL4500 reads 26 to 37 bit HID formats, so match your existing card format before switching brands.
16) Can I standardize a building on the Alarm Lock PDL4500 and keep the mechanical locks matching?
US26D satin chrome is the finish offered, in both hands, which is the most common commercial finish and will read as a match against most existing brushed hardware. Keying can be run keyed alike across a group of doors, or keyed different, or cut to an existing key code so the new locks fall into a master system already in place. Access side is managed by codes and prox rather than keys, with 2,000 users across master, management, supervisor and basic levels, so a property manager can hand out and revoke codes without rekeying anything.
17) My door is 1-3/4 inch. Does the Alarm Lock PDL4500 fit, or do I need a different electronic mortise lock?
The Alarm Lock PDL4500 covers a door thickness range of 1-5/8 inch to 1-7/8 inch, so a 1-3/4 inch door falls inside it. Peers built specifically around 1-3/4 inch doors include the TownSteel FME-2000, a Grade 1 heavy duty classroom mortise lockset with RFID technology, the TownSteel FME-4000 electronic intruder classroom mortise lockset with RFID, and the Schlage CO-100 Grade 1 heavy duty electronic mortise lock with keypad reader. The PDL4500 uses a 2-3/4 inch backset.
18) I need a mortise deadbolt but no keypad or credentials. What replaces the Alarm Lock PDL4500?
The Alarm Lock PDL4500 is an electronic deadbolt function lock whose bolt can be thrown from the outside key cylinder or the inside turn-piece, with a 1 inch stainless steel deadbolt projection. Where no electronics are wanted, the Kaba Ilco 185 Series is a mortise lock in the deadbolt function with no handing, and the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, matching the PDL4500 backset. The Sargent 130KB and 130W are mortise thumbturns for a deadbolt that is operated from the inside by turn rather than by key.
19) Is the Alarm Lock PDL4500 the same kind of product as a keyed mortise lockset like the Cal-Royal NM8080 or Corbin Russwin ML2003?
They are not interchangeable. The Alarm Lock PDL4500 is an electronic, battery operated mortise deadbolt with a 12-button metal keypad and proximity reading that stores 2,000 user codes at the door. The Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors, the Cal-Royal NM8070 is the Grade 1 classroom version with an auxiliary deadlatch, and the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors. Those three control access by key and mechanical function; access changes mean rekeying rather than adding or deleting a code.
20) The opening is exterior and sees hard weather. Which mortise locks besides the Alarm Lock PDL4500 suit it?
The Alarm Lock PDL4500 is built for it: weatherproof rated, with operation from -31 degrees F to +151 degrees F, an all metal weatherproof 12-button keypad, and a proximity antenna housing molded of impact resistant Lexan. Among the electronic peers, the Dormakaba PowerPlex P2066 mortise lock generates its own power at the door rather than depending on line voltage, and the Dormakaba E-Plex E5086 is a Grade 1 pushbutton and card mortise lock in a back-to-back arrangement so both faces carry a reader. Confirm the exterior rating of any peer with its manufacturer before it goes on an outside door.
21) Can a mortise thumbturn or a dummy trim be used in place of the Alarm Lock PDL4500?
No. The Alarm Lock PDL4500 is a complete electronic mortise deadbolt lock with a keypad, proximity reader, latchbolt with 3/4 inch projection and deadlocking latch, and a 1-1/4 inch by 4-7/8 inch strike included. Several items in the same aisle only look like substitutes. The Sargent 130KB and 130W are mortise thumbturns, which is inside trim rather than a lock. The Schlage L0170 is Grade 1 half dummy trim with no keyed function, the Falcon MESC600DT is dummy escutcheon lever trim for M9900 Series exit devices, and the Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan are dummy mortise entrance locksets. None of those latch or secure an opening on their own.
