Alarm Lock PDL3500DBR US26D – Frequently Asked Questions

1) Do I have to specify handing on the PDL3500DB, or is it reversible?
Handing is specified at order, right hand or left hand, and both are stocked in either US26D satin chrome or US3 bright brass. The lock body is reversible in the field, so a crew that shows up with the wrong hand isn't dead in the water, but ordering the correct hand saves the step.
2) Does the deadbolt version actually throw a deadbolt, or is it just a latch?
Both. The DB configuration carries a stainless steel deadbolt with a 1 inch projection plus a stainless latchbolt with 3/4 inch projection and a deadlocking latch. The 1 inch deadbolt throw is what gets you real after-hours security on an exterior or tenant door, which the classroom-function version of the same lock (latchbolt only) does not give you.
3) Will the PDL3500DB latch into the strike already in my frame?
A 1-1/4 x 4-7/8 inch strike is supplied with the lock, and the lock is set up for T-standard and ASA strike preps. If your frame already has an ASA (4-7/8 inch) cutout, you can drop the included strike straight in. A frame prepped for a T-strike works too. Frames with a smaller residential-style strike cutout will need to be modified.
4) What cylinder does the Trilogy PDL3500DB take for key override?
It ships with a 1-3/8 inch mortise cylinder and will accept a mortise cylinder from 1-1/4 to 1-1/2 inches. That range lets a locksmith swap in a cylinder in the building's existing keyway so the override key matches the rest of the master key system. Keying is chosen at order: keyed different, keyed alike, or to a specific key code you supply.
5) How many users can the Alarm Lock PDL3500DB hold and what credentials does it read?
Up to 300 users, each with a 3 to 6 digit PIN and/or an HID proximity card or fob. It reads HID II 26 to 37 bit formats, so a building already issuing HID badges can enroll the same credentials rather than buying a second set. It also keeps an audit trail of access events, which is what most property managers and school districts need for incident review.
6) Does the PDL3500DB need to be wired to power?
No hardwiring. It runs on a 5AA alkaline battery pak, included, rated up to 75,000 cycles. That is the practical reason this lock gets chosen over a wired electrified mortise lock like the BEST 45HW, which needs 12V or 24V run to the door through a hinge transfer. If you want credential control on an opening with no power nearby, the battery unit is the cheaper install.
7) What is the closest alternative to the Alarm Lock PDL3500DB if I need a Grade 1 electronic mortise lock with both a proximity reader and a keypad?
The PDL3500DB is a Grade 1 mortise lock combining a 12-button metal keypad with proximity card reading, 300 user codes and a deadbolt function. The nearest peer combining pushbutton and card credentials in a mortise body is the Dormakaba E-Plex E5086, a Grade 1 entry/egress electronic pushbutton/card mortise lock in the E-Plex 5X86 series. The Schlage Electronics LEMD-GRW is another Grade 1 mortise option with a 125kHz proximity reader and mobile-enabled deadbolt with LED on Greenwich trim, right hand. TownSteel's FME-2000 series is a Grade 1 heavy duty classroom mortise lockset using RFID credentials.
8) I only need keypad codes, not cards. What is a simpler alternative to the PDL3500DB?
If proximity credentials are not part of the plan, look at keypad-only electronic mortise locks. The BEST 45HZ EZ Series is an electronic keypad mortise lock with key override. The Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock for wide stile doors, and the Dormakaba PowerPlex P2066 is a mortise lock in the PowerPlex 2000 series. The Schlage CO-100-MS-40-KP is a Grade 1 standalone electronic mortise lock with a keypad reader in privacy function. The PDL3500DB itself carries both the 12-button metal keypad and proximity reading, so the card side simply goes unused if you choose it anyway.
9) The PDL3500DB runs on batteries. What should I use if the opening is wired to an access control panel?
The PDL3500DB is battery operated on a 5AA battery-pak rated for 75,000 cycles, so it does not tie back to a panel. For a wired opening, the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation. Command Access ML190 is a heavy-duty motorized mortise lock with field selectable EL/EU operation on 24VDC in storeroom function. Schlage's L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, running 12/24VDC.
10) What looks like a substitute for the PDL3500DB but will not work as one?
Several mortise products in the same family solve a different problem. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset - a deadbolt only, with no keypad, no credential reader and no latchbolt. Sargent 130KB and 130W are mortise thumbturns, trim pieces rather than locks. Schlage L0170 is half dummy trim and the Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are dummy function. The PDL3500DB is a full Grade 1 electronic mortise lock with keypad and proximity reading and 300 user codes.
11) Can I use the PDL3500DB on an exterior door in a cold or wet climate?
Yes. The keypad is all-metal, 12 button, and weatherproof, and the proximity antenna housing is molded from impact resistant Lexan. Alarm Lock rates the unit for indoor and outdoor use in extreme temperatures, which is why it turns up on gate houses, tenant entries, and industrial exterior doors rather than only interior corridors.
12) What else should I look at if I want a keypad mortise lock but not proximity cards?
If badges are not part of the plan, the Schlage CO-100 standalone electronic mortise lock is a Grade 1 keypad-only unit, and the BEST 45HZ EZ Series keypad mortise lock includes key override. Both are for 1-3/4 inch doors in the case of the CO-100. The PDL3500DB is the one to keep if you want PIN and HID prox on the same lock plus a deadbolt.
13) Is there an RFID mortise lock alternative to the Alarm Lock Trilogy for a school?
TownSteel's FME-2000 Series is a Grade 1 heavy duty classroom-function mortise lockset with RFID, and the FME-4000 Series adds an intruder classroom function, both for 1-3/4 inch doors. Those are the picks when the requirement is classroom lockdown behavior. The PDL3500DB is a deadbolt function lock and reads HID prox plus keypad, which suits tenant, office, and exterior entries more than a lockdown classroom door.
14) I need this lock on a 1-3/4 inch commercial door with an existing mortise pocket. Is it a straight swap for a mechanical mortise lock?
Mechanically it lines up: 2-3/4 inch backset, standard mortise body, and an ASA strike, so a door already carrying something like a Cal-Royal NM8080 or a Corbin Russwin ML2003 has the pocket and strike prep you need. What changes is the face of the door. The Trilogy adds a keypad and proximity antenna on the outside escutcheon, so the trim footprint is larger than a plain rose or escutcheon lockset and the door face has to be prepped for it.
15) My door is 1-3/4 inch. Does the PDL3500DB fit, or should I look at something else?
The PDL3500DB covers a door thickness range of 1-5/8 inch to 1-7/8 inch, so 1-3/4 inch falls inside it. That thickness is also where most of the peer mortise locks sit: Corbin Russwin ML2003 classroom, Cal-Royal NM8070 classroom and NM8080 storeroom, TownSteel FME-2000 and FME-4000, and Schlage CO-100 are all listed at 1-3/4 inch. Hager's 3800 series passage locks 3810E and 3810S run 1-3/4 inch to 2-1/2 inch if the door is thicker than the PDL3500DB range allows.
16) What is a mechanical Grade 1 mortise lock I can standardize on alongside the PDL3500DB for openings that do not need credentials?
For openings where a key is enough, Grade 1 mechanical mortise locksets in the set include the Accentra 8805FL storeroom with Arcadia lever, Cal-Royal NM8050 office/entrance, NM8070 classroom, NM8080 storeroom with interchangeable core option, and NM8440 privacy with deadbolt, plus the Corbin Russwin ML2003 classroom. Sargent 7925 is a Grade 1 heavy duty corridor/dormitory mortise lock with rose trim and a single cylinder deadbolt. The PDL3500DB stays on the doors that need audit trail and 300 user codes.
17) Is there a lighter duty electronic mortise option than the PDL3500DB for a low traffic door?
The PDL3500DB is a Grade 1 commercial lock built for high traffic openings. For a lighter application, the Codelocks CL2255 is a medium duty electronic tubular mortise latch in the CL2000 series, offered in a brushed steel finish. That is a different build class from a Grade 1 mortise lock with a 1 inch projection deadbolt and a 5AA battery-pak rated to 75,000 cycles.
18) What is an alternative to the PDL3500DB for an outdoor gate or exterior door?
The PDL3500DB is a weatherproof design with an all metal weatherproof 12-button keypad and a proximity antenna housing molded of impact resistant Lexan, rated for indoor and outdoor installation, which is what sets it apart from most electronic mortise locks in its class. Within mortise deadbolt hardware, the Kaba Ilco 185 series is a no-handing mortise lock in deadbolt function, and the Kaba Ilco BR series is a glass door bottom rail lock if the opening is an aluminum storefront rather than a swing door.
19) For a behavioral health or patient room, should I use the PDL3500DB or something else?
The PDL3500DB is a standard commercial electronic mortise lock and is not an anti-ligature design. For those rooms, TownSteel MRX-A-01 is a Grade 1 heavy duty ligature resistant arch trim mortise lockset in passage function, satin stainless steel, and MRX-L-01 is the Grade 1 heavy duty anti-ligature lever version, both at 1-3/4 inch door thickness. Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel.
20) Is there a touchscreen keypad alternative to the PDL3500DB metal pushbutton keypad?
The PDL3500DB uses a 12-button all metal keypad chosen for weatherproof service. If a touchscreen interface is preferred, the Accentra NTM623-NR nexTouch Generation 3 is a Grade 1 mortise lock with a capacitive touchscreen keypad, configured with no deadbolt and cylinder override. Note the function difference: the PDL3500DB is a deadbolt function lock with a 1 inch projection stainless steel deadbolt.
