Alarm Lock DL4100IC US26D – Frequently Asked Questions

1) Will the Alarm Lock DL4100IC fit a 1-3/4 inch commercial door?
Yes. The DL4100IC covers a door thickness range of 1-5/8 to 1-7/8 inches, so the standard 1-3/4 inch commercial door sits in the middle of that range. It won't work on a thin 1-3/8 inch interior door, which falls outside the range entirely.
2) What backset does the DL4100IC pushbutton lock need, and can it go on a 2-3/8 inch bore?
The lock ships with a 2-3/4 inch latch backset, the usual commercial prep. A 2-3/8 inch backset is also available, so an existing 2-3/8 inch cross bore can be matched, but it has to be specified when ordering rather than swapped in the field.
3) Do I have to order a left hand or right hand DL4100IC?
No handing to specify. The DL4100IC is non-handed and the latchbolt is reversible, so one part number covers either swing. That is what makes it practical to stock a single lock across a building with doors swinging both ways.
4) Will the DL4100IC latch into the strike already in my frame?
The latchbolt has a 1/2 inch throw, and 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. If your frame is prepped for either of those, you are covered without buying anything extra. A frame cut for a different strike shape will need the prep worked to match one of the two supplied.
5) Does the DL4100IC come with a core, and which interchangeable cores will it take?
It ships less core, prepped for small format interchangeable core so it can be brought into an existing master key system. The standard model accepts 6 and 7 pin cores from Arrow, KSP, Medeco Keymark and Kaba Peaks. IC models prepped for 6 and 7 pin Yale, Medeco, Sargent, Corbin-Russwin and Schlage are also made. Order the core separately, keyed to your system.
6) Will my existing Schlage or Sargent cylinders work in this Trilogy lock?
The conventional cylinder version uses a 6 pin solid brass cylinder in SC1 keyway, and Schlage, Corbin-Russwin CL, Sargent 480 series, ASSA 65-611 and Lori cylinders all work with the HW620 tailpiece, which is supplied. So a building already keyed in SC1 can bring this lock onto the same key without rekeying the rest of the openings.
7) What does the privacy function on the DL4100IC actually do, and can someone still get out?
An interior pushbutton locks out all basic user codes for a programmable length of time, so the exterior keypad stops working while the room is occupied. An interior LED flashes during the session so occupants can see it is active. Egress is never affected, and the residency feature lets someone leave without having to re-lock the door behind them. That is the behaviour a conference room, exam room or hotel-style application needs.
8) Does the Alarm Lock DL4100IC need to be wired to power or a control panel?
No wiring. It is a standalone battery operated lock running on a 5 AA alkaline pack, included, rated around 60,000 cycles. Every function is programmed at the door through the 12 button all metal keypad, so there is no panel, no reader network and no power run to pull. That is the reason it goes into retrofits where getting power to the opening would mean opening walls.
9) How many users and how much access history does the DL4100IC hold?
2000 PIN or PIN/Prox user codes, 500 scheduled events, and a 40,000 event history log. For a property manager that means one lock can carry every tenant, contractor and staff code on a large building without running out of slots, and the log goes back far enough to reconstruct who entered a room weeks later.
10) Can this pushbutton lock be used on an exterior door or an unheated building?
It is built weatherproof and rated to run from -31 F to +151 F (-35 C to +66 C), which covers exterior openings, unheated warehouses and gate houses in most of North America. Battery locks are the usual weak point in the cold, and that low end is the number to check the spec against.
11) Should I use a cylindrical pushbutton lock like the DL4100IC or a mortise electronic lock?
The DL4100IC is a cylindrical lockset, so it drops into a standard bored door prep with a cross bore and edge bore. That is the faster retrofit and the cheaper prep on an existing wood or hollow metal door. A mortise electronic lock needs a pocket cut into the door edge, which means either a factory prepped door or machining on site. Pick cylindrical when you are replacing an existing knob or lever lock; pick mortise when the opening is already mortise prepped or the spec calls for it.
12) What do I need to order alongside the Alarm Lock DL4100IC to finish the job?
Just the core. Batteries, both strikes, the HW620 tailpiece and self-stick instructional signage are all in the box. Because the lock is supplied less core, you need an SFIC core keyed to your system, and it has to be one of the brands the prep accepts. Nothing else is required, since there is no wiring, no power supply and no panel.
13) What finish does the DL4100IC come in?
Satin chrome, US26D. That is the standard commercial finish, so it matches most existing exit devices, closers and levers already hanging in an institutional or multi-family building without looking like a one-off replacement.
