Alarm Lock DL3075-10B – Frequently Asked Questions

1) Will the Alarm Lock T3 keypad lock fit a standard 1-3/4 inch commercial door?
Yes. The T3 cylindrical lock covers doors from 1-5/8 inch to 1-7/8 inch thick, so a standard 1-3/4 inch commercial door sits in the middle of that range. Outside that band, a 1-3/8 inch older interior door or anything over 1-7/8 inch, it will not fit. It's non-handed, so one unit works on either swing.
2) What backset does the Alarm Lock T3 come with, and will it work in an existing 2-3/8 inch bore?
Standard is a 2-3/4 inch backset, and a 2-3/8 inch version is also available, so both of the usual cylindrical preps are covered. Specify the backset that matches the existing cross-bore centerline when you order.
3) Will the Alarm Lock T3 latch into the strike already in my frame?
Most likely, and both common strikes ship with it. The latchbolt has a 1/2 inch throw and is reversible, and the lock comes with a 1-1/8 x 2-3/4 inch T strike plus a 1-1/4 x 4-7/8 inch ASA strike. If your frame is prepped for either of those, you're set without new frame work.
4) Can I key the T3 into my existing Schlage or Best key system?
Yes, within the listed families. The standard cylinder is a 6 pin solid brass SC1 keyway, and the HW620 tailpiece supplied with the lock lets it accept Schlage, Corbin-Russwin CL, Sargent 480 series, ASSA 65-611 and Lori cylinders. The standard model also takes 6 and 7 pin cores from Best, Falcon, Arrow, KSP, Medeco Keymark and Kaba Peaks. IC core models prepped for 6 and 7 pin Yale, Medeco, Sargent, Corbin-Russwin and Schlage are available as well, so a locksmith keying a building to one system can usually match it.
5) Do I need software or a hardwired connection to program the Alarm Lock T3?
No wiring and no controller. Every function on the T3 is programmed through the 12 button keypad itself, including user codes, timed scheduling and audit trail parameters. It's a standalone battery lock, which is why it suits retrofits where running power to the door isn't practical.
6) What is the closest equivalent to the Alarm Lock T3 keypad cylindrical lock from another manufacturer?
The Alarm Lock T3 is a Grade 1 battery-powered cylindrical lockset with a pushbutton keypad reader and audit trail. The closest peers in the same format are the Accentra nexTouch NTB613, a Grade 1 cylindrical keypad lock with pushbutton entry; the BEST 9KZ EZ Series electronic keypad cylindrical lock with key override; the SDC E75 Series battery-powered electronic cylindrical lockset with keypad access control, listed for 1-3/4 inch to 2-1/8 inch doors; and the TownSteel XCE-2000 Series Grade 1 heavy duty electronic cylindrical keypad lockset for 1-3/4 inch to 2 inch doors. The T3 fits 1-5/8 inch to 1-7/8 inch doors, so verify door thickness against the opening when you swap between them.
7) I need a card or phone credential instead of a PIN pad - what replaces the Alarm Lock T3?
The T3 reader type is a keypad, so codes are the only credential. For credential-based openings, the TownSteel FCE-2000 Series is a Grade 1 standalone motorized cylindrical lockset with RFID, the TownSteel FCE-4000 Series is an RFID electronic classroom cylindrical lockset, the Schlage NDEB ENGAGE Series is a Grade 1 wireless cylindrical lock using 2.4 GHz Bluetooth Low Energy and mobile credentials, and the Schlage XE360M is a Grade 1 wireless tubular lock with a smart mobile reader. All four are Grade 1 like the T3.
8) Can the T3 electronic lock be used on an exterior door?
Yes. The T3 is built weatherproof with tamper-resistant metal construction and an all metal 12 button keypad, so it's rated for interior or exterior openings. No hardwiring is needed outside either, since it runs on 5 AA alkaline batteries that ship with the lock.
9) What does the audit trail on the T3 actually give me?
It logs user access events at the door and reports who entered and when, which is what compliance documentation in healthcare, education and government facilities usually asks for. Combined with multiple user codes and timed scheduling, a property manager can issue individual PINs to contractors or tenants and see which one was used.
10) What other keypad cylindrical locks compare to the Alarm Lock T3?
Close standalone keypad equivalents include the BEST 9KZ EZ Series with key override, the Accentra nexTouch NTB613 Grade 1 pushbutton lock, the SDC E75 Series battery keypad lockset, and the TownSteel XCE-2000 Series Grade 1 keypad lock. Door thickness is where they split: the SDC E75 covers 1-3/4 to 2-1/8 inch and the TownSteel XCE-2000 covers 1-3/4 to 2 inch, while the T3 runs 1-5/8 to 1-7/8 inch. On a thicker door, the SDC or TownSteel is the one that fits.
11) Should I use a standalone keypad lock like the T3 or a networked electronic lock?
The T3 is the right call when you want controlled access and an event log on a handful of doors without pulling wire or standing up a head end: codes and schedules go in at the keypad, and 5 AA batteries power it. If you need credentials pushed and pulled centrally, a wireless or networked lock is the better type, for example the Schlage NDEB ENGAGE Series Bluetooth cylindrical lock (1-5/8 to 2 inch doors) or the Schlage XE360M wireless tubular lock with a mobile reader. Card or fob credentials instead of PINs point to an RFID lock such as the TownSteel FCE-2000 Series.
12) Is there a simpler keyless lock than the Alarm Lock T3 if I do not need an audit trail?
Yes. The T3 carries audit trail logging and is battery powered on 5 AA cells. If you only need code entry, the Lockey 1600 is a heavy duty mechanical keyless knob lock with adjustable backset for 1-1/8 inch to 2 inch doors, and the Lockey 2830 is a mechanical pushbutton keyless knob lock with auto-locking passage function over the same 1-1/8 inch to 2 inch range - both mechanical, so no batteries and no event log. The Lockey E985 and E995 are electronic keypad lever locks for 1-3/8 inch to 1-3/4 inch doors, with the E985 adding key override.
13) My opening has hardwired power available - is there an alternative to the battery-powered Alarm Lock T3?
The T3 runs on 5 AA alkaline batteries with no hardwired connection required. Where low voltage is already run to the door, the SDC Electra 7200 Series is a solenoid controlled cylindrical lock with dual voltage 12/24VDC, listed for 1-3/4 inch to 2 inch doors. It is controlled from an access control system rather than a keypad at the door, so it does not provide the standalone code entry the T3 does.
14) Is the Schlage CO-100 keypad lock the same thing as the Alarm Lock T3?
They are both Grade 1 standalone electronic cylindrical locks with keypads, but they are not interchangeable by function. The Schlage CO-100-CY-40-KP is cataloged as a privacy function heavy duty lock for 1-3/4 inch doors. The Alarm Lock T3 is a Grade 1 cylindrical lockset with audit trail and multi-user code management, fitting 1-5/8 inch to 1-7/8 inch doors. Confirm the function required on the opening and the door thickness before treating one as a drop-in for the other.
15) For a classroom door with intruder lockdown, should I use the Alarm Lock T3 or something else?
The T3 is a Grade 1 keypad cylindrical lock with audit trail and timed scheduling, but for classroom intruder function look at the TownSteel XCE-9000 Series, an electronic classroom intruder cylindrical lockset with keypad for 1-3/4 inch to 2 inch doors, or the TownSteel FCE-4000 Series RFID electronic intruder classroom lockset for 1-3/4 inch doors. The Schlage XE360M is also listed with a classroom/storeroom function. All are Grade 1.
16) Can I use the Kwikset SmartCode 912TNL in place of the Alarm Lock T3 on a commercial door?
The Kwikset 912TNL ZW500 SmartCode is an electronic Tustin lever with Z-Wave, keyed one side, for 1-3/8 inch to 2 inch doors, and it is driven by a home automation controller rather than standalone code administration at the door. The Alarm Lock T3 is specified for commercial use, BHMA Grade 1, with audit trail and multi-user code management. For a commercial or institutional opening the T3 or another Grade 1 keypad lock such as the Accentra nexTouch NTB613 is the closer match.
17) Which electronic cylindrical locks besides the Alarm Lock T3 offer key override?
The Alarm Lock T3 takes a 6 pin solid brass SC1 keyway cylinder, with Schlage, Corbin-Russwin CL, Sargent 480 series, ASSA 65-611 and Lori cylinders compatible using the supplied HW620 tailpiece, plus interchangeable core versions. Among keypad peers, the BEST 9KZ EZ Series is listed with a key override function, and the Lockey E985 is an electronic keypad lever lock with key override. Confirm the keyway matches your existing master key system before committing.
18) I need a Bluetooth smart lock rather than a keypad - what is the alternative to the Alarm Lock T3?
The CENTRIOS CEB100 Series is a Grade 1 smart Bluetooth cylindrical lock listed in privacy function, and the Schlage NDEB ENGAGE Series is a Grade 1 wireless cylindrical lock using 2.4 GHz Bluetooth Low Energy with storeroom, office, privacy and apartment functions for 1-5/8 inch to 2 inch doors. The Alarm Lock T3 stays with a 12 button all metal keypad programmed at the door and logs access events to an audit trail.
19) What finish does the Alarm Lock T3 keypad lock come in?
US10B Oil Rubbed Bronze. If you're standardizing a corridor or a building's exterior doors, that's the finish to match the rest of the hardware to.
20) What mechanical Grade 1 cylindrical lock can I use on openings that do not need the Alarm Lock T3 keypad?
On a project where only some doors need code access, the Dorma C150 is a Grade 1 heavy duty cylindrical lock in entry/office function for 1-3/8 inch to 2-1/4 inch doors, the Dorma C853 is a Grade 1 single cylinder keyed entrance lever for the same thickness range, and the Marks USA 195RAB is a Grade 1 Survivor Series entry clutched lever supplied less core. The Cal-Royal CAL20 covers Grade 1 privacy and the CAL30 Grade 1 passage, both for 1-3/8 inch to 2 inch doors. The T3 keeps the audit trail and keypad on the openings that need them.
