DormaKaba R79K+1SC0+15 RAC4 Surface SC Reader Only

Reader only, no keypad. The R79K+1SC0+15 reads a credential and nothing else, so if your access plan calls for a PIN, or for card-plus-PIN at higher security openings, this is the wrong part. Schlage Electronics MTK15 and MTKB15 are multi-technology readers with an integrated keypad if you need PIN credentials at the door.

No. The R79K+1SC0+15 is built to the RAC4 interface, so it belongs on a dormakaba RAC4 head end. Dropping it onto a third-party panel is not a supported pairing. If the site runs a different platform, look at a reader matched to that system instead, such as the Schlage Electronics MTK15-485 for an RS-485 wiring scheme.

The Securitron R100 is the nearest match on mounting style: it is a surface mounted card reader, the same installation approach as the R79K+1SC0+15, which is a surface mount reader. The R100 belongs to Securitron's RH100 Series and is a wireless card reader, so it communicates back to the access control system over a wireless link rather than the RAC4 system interface the DormaKaba unit uses. Confirm the head end supports the R100's wireless path before swapping, because the two readers do not talk to the same controller in the same way.

Look at the Schlage Electronics MTK15, a networked multi-technology reader with keypad that accepts PIN credentials as well as 125 kHz proximity cards. It is a wall mount unit. The DormaKaba R79K+1SC0+15 is a reader without a keypad, so if the site's credential policy calls for card-plus-PIN at the door, the MTK15 is the part that supports it. For a black single-gang mount version with mobile credential support, the Schlage MTKB15 is the multi-technology reader with keypad in that configuration.

No. The R79K+1SC0+15 is a surface mount reader, so it lands on the wall or frame face rather than trimming out to a single-gang electrical box. For a single-gang opening, the Schlage Electronics MTKB15 is the single-gang mount multi-technology reader with keypad, in black and mobile-enabled. The Schlage MTK15 is a wall mount unit. Match the mounting before matching the credential technology, because the backbox condition is what decides how much wall work the job needs.

Surface mount. The R79K+1SC0+15 fastens to the face of the wall or mullion, which means no back box has to be cut in, useful on block, tile, or an existing finished corridor. If your electrician has already set single-gang boxes, the Schlage Electronics MTKB15 is a single-gang mount reader and drops into that prep instead.

Not on its own. The R79K+1SC0+15 is a wired RAC4 reader and expects a home run back to the access control system. For an opening with no pathway, the Securitron R100 is a surface mounted wireless card reader and avoids the pull.

The Schlage Electronics MTK15 is offered in an RS-485 capable version, catalogued as MTK15-485, alongside the standard MTK15. Both are networked multi-technology readers with keypad, wall mount, taking PIN credentials and 125 kHz proximity cards. The DormaKaba R79K+1SC0+15 is built to the RAC4 system interface, so it is specified by the DormaKaba system it reports to rather than by a raw bus type. Pick the MTK15-485 when the wiring architecture at the door is the deciding factor.

They look alike at the door but they are not interchangeable. The R79K+1SC0+15 is built to the RAC4 system interface and reads credentials only. The MTK15 and MTK15-485 are networked multi-technology readers with keypad that accept PIN credentials and 125 kHz proximity cards, and the MTKB15 adds mobile credentials on a single-gang mount. Substituting one for the other means the credentials issued to the building have to be re-evaluated and the reader has to be brought into the other manufacturer's system, not just re-terminated at the same wires.
