Dormakaba LR1041S-26D-41 – Frequently Asked Questions
1) Can I use the Simplex LR1041 keypad lock on a 3-hour fire rated door?
Yes. The Simplex L1000 cylindrical latch carries a 3-hour UL/ULC fire rating on "A" labeled doors, so it is acceptable on a 3-hour opening. The levers are fixed and ADA compliant, and the lock is listed as Grade 1, which is what most institutional and government specs call for on a main entry or stairwell door.
2) Does the Simplex LR1041 need batteries or wiring?
Neither. This is a fully mechanical pushbutton lock. There is no battery to change and nothing to wire, so it keeps working through a power outage and there is no maintenance cycle to schedule across a portfolio of doors. Access is by a single combination code, which is set through the keypad without pulling the lock off the door. That single-code design is the tradeoff: it suits a shared door where everyone uses the same code, not a building where you need to track who opened what.
3) What do I have to specify when ordering a Simplex LR1041 lever lock?
Four things. Handing, left hand or right hand. Finish: 626 satin chrome and 609 antique brass are the standard finishes, with 605 bright brass and 625 bright chrome offered as options. Backset and latch throw combination, either 2-3/4 inch with the standard 1/2 inch throw, 2-3/4 inch with a 3/4 inch throw, or 2-3/8 inch with the 1/2 inch throw. And the key override cylinder format, covered below. Get handing and backset right against the door before the order goes in, because neither is something you can adjust on site.
4) Can I key the Simplex LR1041 override into my existing Best or Schlage master key system?
That is exactly what the override options are for. Small format interchangeable core is offered for Best and equivalents in 6 or 7-pin length. Large format removable core is offered for Medeco, ASSA, Yale and Abloy in 5 or 6-pin length, Corbin Russwin in 6-pin length, plus Schlage and Sargent. So if the building is already keyed in one of those systems, order the matching override and have your locksmith drop in a core from the existing system. The core is not included with the lock in any of those options, so budget a cylinder separately.
5) What does the passage function on the Simplex LR1041 actually do during business hours?
It lets you hold the door unlocked so people walk through without punching the code, which is what you want on an office or a common room from 8 to 5. The passage feature is switched on from the inside with a thumbturn or key, and that thumbturn or key is included with every passage model. Outside of passage, entry is by combination only, and egress from the inside is always free. The LR1041 is the combination entry plus passage version with key override, so you get the code, the hold-open, and a mechanical key as backup.
6) Is the Simplex pushbutton lock tough enough for an exterior door or a high traffic tenant entrance?
The keypad uses vandal resistant solid metal pushbuttons and the lock is weather resistant, so it is built for an exterior opening rather than an interior office door only. Housing is heavy duty cylindrical with a cast front housing and a unified trim plate, the levers are fixed rather than free spinning, and it is rated Grade 1. It also meets D.O.D. 5220.22M for supplemental access control, which matters if you are specifying for a government or defense contractor facility.
7) Should I put a mechanical Simplex keypad lock on this door or go with an electronic access control lock?
Go mechanical when the door needs one shared code and nobody needs an audit trail. A Simplex L1000 has no batteries, no wiring, no software, and no cards to issue or collect, and it is programmed at the keypad without taking the lock off the door. The limit is the single access code: change it and every user has to be told the new one, and you get no record of who entered. If you need per person codes, scheduled unlock, or an entry log, this is the wrong lock type and you want an electronic access control lockset instead.
8) Can I standardize the same Simplex keypad lock across a whole building of doors?
Yes, and the finish and cylinder options are what make it match. The same lever lock is available in 626 satin chrome, 609 antique brass, 605 bright brass and 625 bright chrome, so you can hold one finish across every opening you convert. Ordering the same key override format on every door means one core type and one master key system for the whole building. Handing is per door, so walk the openings and count left hand and right hand before placing a bulk order.
