Alarm Lock DL5200/26D – Frequently Asked Questions

1) Will the Alarm Lock DL5200 fit a standard 1-3/4 inch commercial door?
Yes. The DL5200 covers a door thickness range of 1-5/8 to 1-7/8 inches, so a 1-3/4 inch commercial door sits right in the middle of that band. It uses a 2-3/4 inch backset as supplied, with 2-3/8 inch available if you specify it at the time of order. If your door is thinner than 1-5/8 or thicker than 1-7/8, this is the wrong lock for that opening.
2) Can I put the DL5200 in an existing 161 cylindrical prep without redrilling the door?
In most cases yes, provided the prep is on a 2-3/4 inch backset and the door falls in the 1-5/8 to 1-7/8 inch range. The DL5200 is a cylindrical lockset that goes into the same bored prep a standard commercial cylindrical lock uses, and it is non-handed, so you don't need to know the swing before ordering. Both strikes come in the box: a 1-1/8 x 2-3/4 inch T strike and a 1-1/4 x 4-7/8 inch ASA strike, so whichever way the frame is prepped, you already have the strike for it.
3) What does double-sided mean on the DL5200, and when do I actually need keypads on both sides?
Both faces of the door carry a 12-button metal keypad, and a user's PIN works from either side. That matters where you have to control traffic in both directions: a stairwell or tenant corridor where you don't want free egress-side entry back through, a shared equipment or mechanical room between two spaces, a pool or amenity gate. Programming is done from the keypad on either side, so a code you add once works both ways rather than being entered twice. If you only need to control entry from one side and want free exit, a single-sided keypad lock is less hardware to install and program.
4) Will the DL5200 key override work with my existing Schlage keys?
The standard cylinder version ships with a 6 pin solid brass cylinder in SC1 keyway, so it takes a standard Schlage key section out of the box. If you key your building on something else, the lock accepts Schlage, Corbin-Russwin CL, Sargent 480 series, ASSA 65-611 and Lori cylinders using the HW620 tailpiece, which is supplied. Keying is specified at order: keyed different, keyed alike, or to a key code you provide.
5) I run my building on small format interchangeable core. Does the DL5200 come SFIC?
Yes, there is an SFIC version. The DL5200 is ordered either as Standard, which comes with the conventional key override cylinder, or as IC, which is prepped for a small format interchangeable core and ships less core, so you supply and stamp your own core to match the rest of your system. Pick the IC version if your maintenance team already cores its own doors; pick Standard if you want a working key in the box.
6) What do I have to specify when ordering an Alarm Lock DL5200?
Four decisions. Cylinder: Standard with conventional key override, or IC prepped for SFIC less core. Finish: US26D satin chrome or US10B oil rubbed bronze, and both finishes are offered in either cylinder version. Keying: keyed different, keyed alike, or to a specific key code you supply. And backset, since 2-3/4 inch is standard and 2-3/8 inch has to be called out at the time of order. Batteries and both strikes are already in the box.
7) How long do the batteries last on the DL5200, and do I need to run power to the door?
No wiring at all. The DL5200 runs on 5 AA alkaline batteries, included, and Alarm Lock rates it at 80,000 cycles typical operation on a set. That is the reason property managers use this on gates, exterior storage, and remote openings where pulling power is the expensive part of the job. If you want a lock that runs off building power instead, the SDC Electra 7200 Series is a solenoid controlled cylindrical lock on dual voltage 12/24VDC.
8) My doors are 1-3/4 inch but some are thicker. What electronic cylindrical lock do I use where the DL5200 does not fit?
The DL5200 tops out at 1-7/8 inches. For thicker doors, ZenSupply carries the TownSteel XCE-2000 Series electronic keypad cylindrical lockset rated 1-3/4 to 2 inches, and the SDC E75 Series battery powered keypad lockset rated 1-3/4 to 2-1/8 inches. Going the other way, on thin doors under 1-5/8 inches, the Lockey 2830 mechanical pushbutton knob lock covers 1-1/8 to 2 inches, though that one is mechanical rather than electronic.
9) What is the closest equivalent to the Alarm Lock DL5200 if I need keypad entry on both sides of the door?
The DL5200 is a battery-operated cylindrical keypad lock with a metal 12-button keypad on both sides of the door, so all programming and PIN entry can happen from either face. Among battery-powered keypad cylindrical locksets, the SDC E75 Series is the nearest peer in construction, though it is set up for a 1-3/4 inch to 2-1/8 inch door thickness where the DL5200 covers 1-5/8 inch to 1-7/8 inch. The TownSteel XCE-2000 Series is another Grade 1 electronic cylindrical lockset with a keypad, in a Classroom function on a 1-3/4 inch to 2 inch door. If double-sided code entry is the actual requirement rather than just keypad access, confirm that against the peer before substituting - both of those are keypad locksets, and the DL5200 is specifically the double-sided design.
10) My door is 2 inches thick - what keypad cylindrical lock fits when the DL5200 does not?
The DL5200 is built for a 1-5/8 inch to 1-7/8 inch door, so a 2 inch door is outside its range. The TownSteel XCE-2000 Series, a Grade 1 electronic cylindrical lockset with keypad, is rated 1-3/4 inch to 2 inch, and the TownSteel XCE-9000 Series electronic classroom intruder lockset with keypad covers the same 1-3/4 inch to 2 inch range. The SDC E75 Series battery-powered keypad lockset goes further at 1-3/4 inch to 2-1/8 inch. All three sit above the DL5200's range at the thick end, so measure the actual door leaf before choosing.
11) What should I use instead of the DL5200 if the opening needs to be on a credential or card system rather than PIN codes?
The DL5200 is a standalone keypad lock - access is by PIN code entered on the keypad, with a conventional cylinder key override. For openings that need credentials instead of codes, the TownSteel FCE-2000 Series is a Grade 1 standalone motorized cylindrical lockset with RFID technology in a Classroom function, and the TownSteel FCE-4000 Series is an RFID electronic intruder classroom cylindrical lockset. The Schlage NDEB is a Grade 1 ENGAGE Series cylindrical lock with a 2.4 GHz Bluetooth Low Energy reader for mobile credentials, on a 1-5/8 inch to 2 inch door - the only one of the three whose thickness range overlaps the DL5200's 1-5/8 inch to 1-7/8 inch. The CENTRIOS CEB100 is a Grade 1 smart Bluetooth cylindrical lock in a Privacy function, which is a different function from a keyed-override entry lock.
12) Can I substitute the Schlage CO-100 keypad lock for an Alarm Lock DL5200?
Check the function and the door before treating them as interchangeable. The Schlage CO-100 standalone electronic cylindrical lock is a Grade 1 heavy duty keypad lock with cylinder options, but it is a Privacy function and is specified for a 1-3/4 inch door thickness. The DL5200 is an entry-style keypad lock with conventional cylinder key override that fits 1-5/8 inch to 1-7/8 inch with a 2-3/4 inch backset. A Privacy-function lock is intended for a room that locks from the inside, not for a controlled entrance, so it is a substitute only if the opening's function schedule actually calls for privacy.
13) The DL5200 runs on batteries - what electronic cylindrical lock do I use if the opening is wired to an access control panel?
The DL5200 is battery operated, which is what lets it go in without pulling power to the door. When the opening is already tied to a panel or needs to release from a remote input, the SDC Electra 7200 Series is a solenoid controlled cylindrical lock running on dual voltage 12/24VDC, on a 1-3/4 inch to 2 inch door. That is a fundamentally different install - a wired lock takes power and a transfer hinge or door loop, where the DL5200's 5 AA batteries are self-contained.
14) For a classroom lockdown requirement, is the DL5200 the right electronic lock?
The DL5200 is a double-sided keypad entry lock with conventional cylinder override - code access on both faces, which is not the same thing as a classroom intruder function. Where the specification calls for lockdown, the TownSteel FCE-4000 Series is an RFID electronic intruder classroom cylindrical lockset and the TownSteel XCE-9000 Series is an electronic classroom intruder cylindrical lockset with keypad, both Grade 1 heavy duty on a Classroom function; the XCE-9000 fits 1-3/4 inch to 2 inch doors. The Schlage XE360M is a Grade 1 wireless tubular lock with an offline push button function in a Classroom/Storeroom function on a 1-3/4 inch door. Match the function on the door schedule first, since these differ from the DL5200 in function, not just in credential type.
15) Can I use the DL5200 on an exterior door in a cold climate?
Yes. Operating range is -31F to +151F, which covers northern winters and unconditioned equipment rooms and rooftop access. It is a commercial rated lockset, not a residential one. Note the thickness limit though: 1-5/8 to 1-7/8 inches. A heavy insulated exterior door thicker than 1-7/8 inches is outside its range.
16) How many user codes can the DL5200 hold, and is that enough for a 40 unit building?
Up to 100 user PIN codes, programmed at the keypad with no software, no cable, and no laptop. For a 40 unit property that leaves room for every tenant plus maintenance, cleaning, and contractor codes. Because it is double sided, one code entry covers both faces of the door rather than being programmed twice. Where you need more than 100 users, or audit trail and mobile credentialing, look at a networked or Bluetooth platform such as the Schlage NDEB ENGAGE Series wireless lock.
17) What is the difference between the Alarm Lock DL5200 and other Grade 1 keypad cylindrical locks?
The separator is the second keypad. Most standalone Grade 1 keypad cylindrical locks put the keypad on one side only, including the Accentra nexTouch NTB613, the BEST 9KZ EZ Series with key override, and the TownSteel XCE-2000 Series. The DL5200 puts a 12 button metal keypad on both faces with codes valid from either direction and programming available from either side. Choose it when the door has to be controlled in both directions. If you only need controlled entry from one side, a single sided unit is cheaper to install and there is less to program.
18) I need a classroom intruder function lock, not a keypad code lock. Is the DL5200 the right choice?
No. The DL5200 is a PIN code access lock with key override, not a classroom security lockset. For a classroom intruder application ZenSupply carries the TownSteel XCE-9000 Series electronic classroom intruder cylindrical lockset with keypad, and the TownSteel FCE-4000 Series RFID electronic intruder classroom lockset, both Grade 1. Use the DL5200 for offices, storage, mechanical rooms, and tenant doors where controlling who has a code is the requirement.
19) If the batteries die on the DL5200, am I locked out?
No. Every DL5200 ordered as the Standard cylinder version includes a conventional key override cylinder, so a mechanical key gets you in regardless of battery state. The IC version is prepped for the same purpose but ships less core, so keep a core in it rather than leaving the prep empty. That override is also how you get back in during programming mistakes, not just dead batteries.
20) Is there a simpler keyless option than the Alarm Lock DL5200 if I do not need 100 user codes or batteries?
The DL5200 is battery operated on 5 AA cells and holds up to 100 user codes with keypad programming. When a facility only needs one code and no battery maintenance, the Lockey 1600 heavy duty mechanical keyless knob lock with adjustable backset and the Lockey 2830 mechanical pushbutton keyless knob lock, a passage function with auto-locking, are mechanical pushbutton locks with no power source at all. Both are rated for a 1-1/8 inch to 2 inch door, wider than the DL5200's 1-5/8 inch to 1-7/8 inch. The trade is that a mechanical pushbutton lock has no user database and no audit of who entered which code.
21) I need to key an electronic lock into an existing small format interchangeable core system - how does the DL5200 compare to other keypad locks?
The DL5200 is sold in an SFIC prep, less core version alongside the standard conventional cylinder key override version, in Satin Chrome US26D and Oil Rubbed Bronze US10B. Among the keypad peers, the BEST 9KZ EZ Series is an electronic keypad cylindrical lock with a key override function, and the Accentra nexTouch NTB613 is a Grade 1 cylindrical keypad lock with pushbutton entry. If the core system is the deciding factor, specify the DL5200 SFIC prep version and confirm the peer's cylinder prep before swapping, since a lock supplied with a conventional cylinder will not take your existing core.
22) What is the difference between the DL5200 and a mechanical Grade 1 entry lockset like the Dorma C150?
The DL5200 is an electronic keypad lock - PIN codes for up to 100 users on both sides of the door, running on 5 AA batteries, with a conventional cylinder for key override. The Dorma C150 is a Grade 1 heavy-duty cylindrical lock in an Entry/Office function from the C100 Series, keyed only, with a 1-3/8 inch to 2-1/4 inch door thickness range that is wider than the DL5200's 1-5/8 inch to 1-7/8 inch. The Dorma C853 is a Grade 1 Entrance single cylinder lever lockset on the same 1-3/8 inch to 2-1/4 inch range. A keyed mechanical lockset means issuing and rekeying physical keys; the DL5200 means adding and deleting codes at the keypad and changing batteries.
23) Is the Kwikset SmartCode 912TNL an alternative to the Alarm Lock DL5200 for a commercial opening?
They are built for different service. The DL5200 is a BHMA Certified Grade 1 heavy duty cylindrical lockset with a UL Listed 3 hour fire rated latchbolt and an all-metal 12-button keypad, and is a commercial product. The Kwikset 912TNL ZW500 SmartCode electronic Tustin lever with Z-Wave technology is a Keyed One Side function on a 1-3/8 inch to 2 inch door in the SmartCode series. The Z-Wave lever is aimed at a home automation hub rather than a standalone commercial door, and it does not carry the Grade 1 fire-rated cylindrical construction the DL5200 does.
24) Which lock matches the DL5200's 2-3/4 inch backset and ASA strike if I am standardizing door prep across a building?
The DL5200 uses a 2-3/4 inch backset and ships with both a 1-1/8 inch x 2-3/4 inch T strike and a 1-1/4 inch x 4-7/8 inch ASA strike, so it drops into either prep. The Stanley Security QCL150 is prepared the same way - a square 2-3/4 inch backset latch with a 4-7/8 inch x 1-1/4 inch ASA strike, on a Grade 2 Entrance lever in the QCL100 Series. The Marks USA 175RF SFIC is a Grade 2 storeroom clutched lever lockset with a 2-3/4 inch backset and an ANSI strike, less core. Those two share the DL5200's prep, which matters when a facility keeps one door prep across mechanical and electronic openings.
25) Is the Lockey E985 or E995 keypad lever lock the same kind of product as the DL5200?
Both are electronic keypad locks, but they differ in door range and form. The Lockey E985 and Lockey E995 are electronic keypad lever locks with remote control - the E985 with key override, the E995 battery powered - and both are rated for a 1-3/8 inch to 1-3/4 inch door. The DL5200 fits 1-5/8 inch to 1-7/8 inch, so the ranges overlap only between 1-5/8 inch and 1-3/4 inch. The DL5200 is a BHMA Certified Grade 1 heavy duty cylindrical lockset with a UL Listed fire rated latchbolt and keypads on both sides of the door; the Lockey units add remote control operation, which the DL5200 does not have.
26) What finishes does the Alarm Lock DL5200 come in, and will they match the rest of my building hardware?
Two finishes: US26D satin chrome and US10B oil rubbed bronze. Both are available with either the standard key override cylinder or the SFIC prep, so the finish choice does not limit your cylinder choice. US26D is the usual commercial match for brushed chrome and satin stainless lever hardware already hanging in most office and institutional corridors; US10B suits darker bronze trim packages.
27) Do I need an electronic lock like the DL5200 on every door, or can the non-access-controlled openings take something else?
Only the openings that need code-controlled entry need the DL5200's keypad and 100 user codes. Interior doors that just need to latch take a passage lockset - the Cal-Royal CAL30 is a Grade 1 extra heavy duty Passage lock in the Calypso Series on a 1-3/8 inch to 2 inch door, and the Marks USA 195N is a Grade 1 Passage lever in the Survivor Series with ADA compliant levers. Restrooms and similar take a privacy function such as the Cal-Royal CAL20, Grade 1 extra heavy duty Privacy on the same 1-3/8 inch to 2 inch range. The DL5200 also has ADA compliant levers, so a building can mix these functions and stay consistent on lever style and grade.

    A Convenient and Secure Cylindrical Lock for Peace of Mind

    Posted by Aiden on Jul 11th 2023

    Hey everyone, I recently got my hands on the Alarm Lock DL5200 Series Double-Sided Pushbutton Cylindrical Lock from ZenSupply.com, and I'm loving the convenience it offers. The double-sided pushbutton feature allows me to lock and unlock the door from both sides, which is super handy. The lock provides excellent security too, giving me peace of mind. However, one drawback to note is that the installation process can be a bit challenging for those with limited DIY experience. Overall, though, it's a reliable and secure choice.
