Medeco 100400H G-26 – Frequently Asked Questions
1) Can I add electronic access control to an existing door without running wire to it?
That is the point of the Medeco XT rim cylinder. It drops into existing hardware in place of a standard rim cylinder and takes no wiring at the door, because power comes from the rechargeable Medeco XT key (sold separately). For a property manager or integrator with occupied buildings, that means no door prep for wire, no power supply, and no transfer hinge. The cylinder itself stores the access decisions and the log.
2) What is the difference between the horizontal and vertical tailpiece on the Medeco XT 100400 rim cylinder?
The tailpiece orientation has to match the hardware it drives. The 100400 is ordered with either a horizontal or a vertical tailpiece, and every one of the 13 finishes is offered in both. Pull the existing rim cylinder off the door and look at the tailpiece as installed on the lock body; order the XT cylinder in that same orientation. Getting this wrong is the most common reason a rim cylinder will not operate the device it is mounted behind.
3) Will a Medeco XT cylinder work outdoors in freezing weather?
Rated -40F to 140F, indoor or outdoor. The shell is stainless steel and the substrate brass, so gate hardware, exterior storefront, warehouse man-doors, and unconditioned stairwells are all in range. There is no battery in the door to go flat in the cold, since the key carries the power.
4) Do I get an audit trail on the door itself, or only at the key?
Both. The XT cylinder holds up to 2,000 audit events in non-volatile memory at the door, and each key stores up to 5,000 events of its own. For healthcare, government, and multi-tenant work where you need to prove who opened a specific opening and when, the cylinder record survives without power and without a network connection to that door.
5) What happens if an employee loses an XT key or quits without turning it in?
Blacklist it. A lost or stolen key can be flagged so it stops working, and you do not pull or rekey the cylinder to do it. Keys also carry operating and expiration schedules, so a contractor key can be set to die on a date rather than relying on someone handing it back. That is the practical reason facilities move to XT from mechanical keying: turnover stops meaning a rekey.
6) I just need a plain mechanical rim cylinder, not an electronic one. What should I look at instead?
If there is no audit trail or scheduling requirement, the XT is more cylinder than the job needs. The Kaba Ilco 605 Series 5-pin replacement rim cylinder is the straight mechanical swap. For an exit device where the outside trim is never meant to unlock, the Ilco 7010 is a dummy rim cylinder, and where you want a thumbturn instead of a key, the Ilco 7011 turnknob rim cylinder or the ADA 7011 covers it. All three Ilco cylinders are 1-1/8 inch.
7) What is the difference between the Medeco 100400 XT rim cylinder and a Kaba Ilco 605 Series replacement rim cylinder?
Both are rim cylinders that drop into existing rim hardware, but they solve different problems. The Kaba Ilco 605 Series is a 5 pin mechanical replacement rim cylinder, keyed and operated entirely by the cut of the key. The Medeco 100400 is an electronic XT cylinder: it needs no wiring because the rechargeable XT key carries the power, it stores up to 2,000 audit events in non-volatile memory, and lost or stolen keys can be blacklisted so they stop working without pulling the cylinder. If the opening only needs a key to turn a rim device, the Ilco 605 Series does that. If someone has to prove later who opened the door and when, that is the Medeco XT.
8) I need a rim cylinder for a door that is never locked, just needs the hole filled. Is the Medeco 100400 overkill?
Yes. For an opening that needs the cylinder hole covered with no locking function, the Kaba Ilco 7010 is a dummy rim cylinder in a 1 1/8 inch (28.6mm) size. The Medeco 100400 XT is a Grade 1 electronic access control cylinder with on-board audit memory and key blacklisting, built for openings where access has to be controlled and logged. A dummy cylinder does not accept a key at all.
9) How many doors can one Medeco XT key open, and how often does it need charging?
One XT key addresses up to 5,000 cylinders and delivers 1,500 to 1,800 openings per charge with the cylinder unlock time set to 0.8 seconds. For a route-based user, a maintenance tech or a guard covering a campus, that is a full duty cycle between charges. Keys are sold separately from the cylinder, so budget them into the order.
10) Is the Medeco XT rim cylinder rated for high-traffic commercial doors?
BHMA Grade 1 and classed heavy duty commercial, with a stainless steel shell built for drill and tamper resistance. Grade 1 is the top BHMA tier and the one normally specified on institutional and commercial openings, so this meets a spec calling for a Grade 1 cylinder. It is not a residential part.
11) Do I need a server or software system to run Medeco XT cylinders?
Not necessarily. XT supports stand-alone, network, web-hosted, and mobile programming, and all programming happens at the key rather than at the door. A small property can run stand-alone with no infrastructure; a REIT or a multi-site institution can run it hosted or networked. The cylinder hardware is the same either way, so the decision does not change what you order here.
12) Can I phase electronic cylinders in a few doors at a time instead of doing the whole building?
Yes, and that is how most XT rollouts go. Because each cylinder is self-contained, retrofits into existing hardware, and needs no wiring, you can convert the sensitive openings first, IT rooms, pharmacy, cash office, records, and leave the rest mechanical. The key programming, schedules and audit log all live in the key and cylinder, so there is nothing building-wide to commission before the first door works.
13) What do I use on the inside of the door if the Medeco XT cylinder is on the outside?
For the inside of a rim device where you want thumbturn release rather than key operation, the Kaba Ilco 7011 is a turnknob rim cylinder in 1 1/8 inch (28.6mm), and the Kaba Ilco ADA 7011 is the turnturn version in the same 1 1/8 inch (28.6mm) size. The Medeco 100400 XT is key-operated and takes the rechargeable Medeco XT key, so it belongs on the credentialed side of the opening where the audit trail is wanted.
14) Is a Kaba Ilco turnknob rim cylinder a substitute for the Medeco 100400 XT?
No. The Kaba Ilco 7011 and ADA 7011 are turnknob rim cylinders, operated by hand from one side rather than by a key or credential. The Medeco 100400 XT is a Grade 1 heavy duty electronic cylinder with a stainless steel drill and tamper resistant shell, 2,000 audit events in memory, and a -40F to 140F operating range for interior or exterior use. Swapping one for the other changes the opening from controlled and logged access to free egress-style hand operation.
15) We are standardizing rim cylinders across a facility and buying in bulk. How does that change the choice against the Medeco 100400?
The Kaba Ilco 605 Series 5 pin replacement rim cylinder is sold by 10s, which suits a mechanical standardization across many like openings. The Medeco 100400 XT is programmed at the key and supports stand-alone, network, web-hosted, and mobile programming, with each key holding operating and expiration schedules and reaching up to 5,000 cylinders. A mixed facility often runs both: mechanical rim cylinders on the low-risk doors and XT cylinders on the openings that need scheduled access and an audit record.
16) Can I match the Medeco XT rim cylinder to the finish of the exit devices already on my building?
Thirteen finishes are offered, in both tailpiece orientations: 605 bright brass, 606 satin brass, 609 antique brass, 611 bright bronze, 612 satin bronze, 613 dark bronze oil-rubbed, 618 bright nickel, 619 satin nickel, 20 antique nickel, 622 flat black, 624 dark bronze, 625 bright chrome and 626 satin chrome. For fleet work where the rest of the opening is 626 satin chrome or 613 oil-rubbed bronze, the cylinder will not stand out as the odd part on the door.
