InSync Lock Series

InSync locks work together with SAM RF software to create a single system that manages both key and access control at perimeter entries, amenity and utility doors as well as apartment or bedroom doors. With the InSync system, administrators only need to program the locks once; the software continually manages critical informational changes such as access privileges and move ins/outs. This information is delivered automatically to each lock via the InSync key once the “New” version of the key is created and used in the locks. Only one key is required for use at multiple access points, creating a convenient and efficient “No Touring” user experience. InSync lock models accommodate virtually all door types and preparations, and common area/amenity applications. The locks feature contemporary finishes and lever options to complement today’s design trends.

  • Unit — Designed for apartment entry, offices, utility rooms, and more
  • Suite — Ideal for multiple leases per apartment, such as student housing
  • Common — Used for perimeter entries and amenity spaces
  • Entry — Used to make an InSync Unit lock behave like a hotel lock; the lock will always automatically re-lock behind a resident
  • Suite Egress — Used to make a Suite lock act like a Unit lock where the key or the thumbturn is used to manually re-lock the lock
 

SAM RF Software & Hardware: The Windows-based SAM RF software, the encoder (key-encoding device), and the handheld utility device for programming the locks are separate items:

Product details

The InSync Access Control System has different configurations to accommodate various applications, from unit and suite to elevator and pool access. 

 

InSync I and D Unit Locks

The I and D unit configurations provide operational functionality for individual entry doors. Rotation of the inside thumbturn or the inserted RFID key extends or retracts the 1" dead bolt locking or unlocking the door. In the locked position, only duplicate resident and authorized service keys can access the unit. Unit locks are programmed with one resident code (change key). Each key made with one resident code can have up to 64 unique identity codes.

 

InSync M and L Unit Locks

The M and L unit configurations provide true residential entry lock functionality. Each time the inside lever is rotated, the lock goes into a “toggled” condition which eliminates the possibility of lock outs. When the key is inserted into the lock after egress, the lock is placed back into a locked position. An audit trail is created and stored within the lock for each occurrence. The inside thumbturn, when turned, will toggle the lock between unlocked and locked. Multiple residents can have access to the same unit if needed. All residents are completely unique in the system and are tracked individually.

 

InSync I, D, M and L Suite Locks

The suite configuration allows ingress and egress to multiple residents who need to access individual unit doors located behind the suite door. A resident uses the InSync I and D suite locks just like a traditional door lock.  The resident throws the dead bolt using the interior thumbturn or rotating the key in the lock after ingress or egress to relock the door. M and L suite locks have no interior thumbturn and always remain in a locked position after ingress or egress. Suite locks can recognize up to 20 unique resident codes.

 

InSync RAC Common Area Access

InSync RAC and CP products are available as either standalone battery- operated door locks or hard-wired AC/DC electrically powered devices designed to work in conjunction with other electronic latching hardware.
RAC works in conjunction with remote access points including elevators, outdoor pools, roll-up garage doors, parking arms, electric strikes, magnets, and telephone entry systems.

Dormakaba RMB420C-26D – Frequently Asked Questions

1) Is the Dormakaba InSync RMB420C a keypad lock, or does it use a card or key fob?
The InSync locks are RFID key operated, not keypad. Access is carried on an InSync key, and the same key works at multiple access points so a resident or staff member carries one credential for the whole property. The lock is battery operated and electronic, and programming changes ride in on the key itself once a "New" version of the key is created and used in the lock. That is what dormakaba calls the "No Touring" model: administrators program a lock once and the software pushes access privileges and move in/move out changes without anyone walking the building.
2) What does the "Common" configuration on the RMB420C InSync mortise lock mean, and where should I use it?
Common is the configuration for perimeter entries and amenity spaces, the lobby door, the fitness room, the mail room, the utility door. It is not the configuration for an apartment or bedroom door. Those use Unit (individual apartment entry, offices, utility rooms), Suite (multiple leases behind one door, like student housing), Entry (makes a Unit lock behave like a hotel lock and always re-lock behind a resident), or Suite Egress (makes a Suite lock act like a Unit lock, re-locked manually by key or thumbturn). Pick the configuration by the door's job, because it is built into the lock, not set in the field.
3) Can the InSync CM style ASM mortise lock go on a fire rated door?
Yes. The InSync CM electronic lock with ASM mortise is available with a UL 20-minute or 3-hour rating, so it covers both a 20-minute rated corridor or utility door and a 3-hour rated opening. Confirm which rating you are ordering, since the two are separate builds and the label on your door frame decides which one is legal.
4) Does the RMB420C InSync lock have a deadbolt?
No deadbolt on this one. It is the no-deadbolt Common area build, latch only, which is what you want on a perimeter or amenity door where people pass through constantly and nobody should be throwing a bolt behind them. If you need a bolt, the InSync M unit configuration carries a 1 inch automatic deadbolt and the I and D unit configurations have a 1 inch deadbolt thrown by the interior thumbturn or by rotating the key.
5) What is Left Hand Reverse handing and can I change it in the field on this lock?
Left hand reverse means the door is hinged on the left as you face the outside of it and swings out toward you. That is the typical condition on an exterior perimeter door, which is where a Common area lock lives. This lock is ordered handed, so stand outside the opening and confirm the hinge side and swing before you order. Some competing mortise bodies are field reversible, such as the BEST 45H public entrance body and the Falcon MA101, but that is a different product, not a setting on this one.
6) What else do I have to buy to get an InSync lock system running?
The locks alone will not do anything. The Windows based SAM RF software, the encoder that writes the keys, and the handheld utility device that programs the locks are all separate items you order alongside. ZenSupply carries the dormakaba R21220 SAM RF Encoder with extra memory (power cord not included), the R21190 SAM RF Utility Device with extra memory (battery not included), and the R20470 SAM RF Emergency Lock Power Supply for jumping a lock whose batteries have died. Budget for the head end on the first job; on later doors you are only buying locks.
7) I need access control on a common area door that already has panic hardware. Is a mortise lock the right choice?
No, not on an exit device opening. Cutting a mortise pocket into a door with rim or vertical rod panic hardware is the wrong approach. The InSync CP electronic lock is built for exactly that case: it works in conjunction with rim and surface mount vertical rod exit hardware and interfaces with industry exit devices, so the panic bar stays and the credential controls it. Use the ASM mortise version where the door takes a standard mortise lock instead. If the access point is an elevator, garage door, parking arm, electric strike, magnet, or telephone entry, the InSync RAC remote access controller is the piece for that; it switches electrified locking devices up to 24 volts AC/DC and works as an elevator control unit with a single relay.
8) The InSync line is discontinued. What can I put on a common area door instead?
Several current electronic mortise locks cover the same common area job. The TownSteel FME-2000 Series is a Grade 1 heavy duty mortise lockset with RFID technology for 1-3/4 inch doors, which is the closest credential-for-credential swap if you are moving off an RFID key. Schlage Electronics offers the LEMD-GRW, a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating, and the CO-100 standalone electronic mortise lock. If you would rather run PIN codes than credentials, the Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise lock with 300 user codes for 1-5/8 to 1-7/8 inch doors. Match the door prep and handing before you commit; these are different lock bodies, not drop-in InSync replacements.
9) What is the closest equivalent to a Dormakaba RMB420C InSync common area mortise lock from another manufacturer?
The RMB420C is a battery operated electronic mortise lock with a lever handle for common area and utility openings. Comparable battery-free-of-wiring electronic mortise locks include the TownSteel FME-2000 Series, a Grade 1 heavy duty mortise lockset with RFID technology in a classroom function, and the Accentra NTM623-NR nexTouch Generation 3 Grade 1 mortise lock with a capacitive touchscreen keypad and cylinder override. The FME-2000 uses RFID credentials like the InSync key does, while the NTM623-NR is keypad driven with a mechanical cylinder override on the outside.
10) What electronic mortise lock should I use if the opening needs to be hard wired instead of battery powered?
The RMB420C runs on battery power at the door. Where the opening is already wired or the access control system requires a powered lock, the BEST 45HW Series is a wired electromechanical mortise lock with 12V/24V operation in a heavy duty body, and the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation for 1-3/4 inch doors. The Command Access ML190 Series is a heavy-duty motorized mortise lock with field selectable EL/EU operation on 24VDC in a storeroom function.
11) What should I use instead if the common area door already has exit device hardware or a glass bottom rail?
A mortise lockset like the RMB420C needs a mortise pocket in the door. Where the opening carries a rim or vertical rod exit device, the InSync C Series CP model works in conjunction with rim and surface mount vertical rod panic hardware for common area doors. On aluminum storefront with Adams Rite style prep, the Alarm Lock DL1300NW Trilogy Networx is a wireless electronic mortise lock with keypad built for Adams Rite deadlatches, and the Kaba Ilco BR Series is a glass door bottom rail lock.
12) Does the RMB420C need handing like other mortise locks, and what if my opening is the other hand?
The RMB420C is built left hand reverse, so the hand is fixed at order. Several mortise peers are field reversible instead: the BEST 45H Series heavy duty mortise lock body in public entrance function is field reversible, and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating. Handed peers include the Baldwin 6310190RRLS, a right hand reverse entry/storeroom lever by lever mortise lock with 2-1/2 inch backset for doors 1-3/8 inch and over.
13) I need a fire rated mortise lock for a stair or corridor opening. What compares to the InSync mortise?
The InSync M mortise models carry a UL 20-minute or 3-hour fire door rating. Fire rated peers include the Schlage Electronics LEMD-GRW, a Grade 1 ENGAGE Series wireless mortise lock with a 3 hour fire rating, the Schlage LEBMB-ADD at Grade 2 with a 3 hour fire rating on 1-3/4 inch doors, and the Falcon MA101, a Grade 1 heavy duty mortise passage lock carrying a fire rating.
14) The InSync line has a discontinuation notice. What current electronic mortise locks cover the same common area application?
For a common area or amenity opening that was specified with an InSync mortise, current electronic mortise options include the TownSteel FME-2000 Series, Grade 1 heavy duty with RFID technology for 1-3/4 inch doors, the TownSteel FME-4000 Series electronic intruder classroom mortise lockset with RFID technology, also Grade 1 heavy duty on 1-3/4 inch doors, and the Schlage CO-100 standalone electronic mortise lock, Grade 1 heavy duty with a keypad reader on 1-3/4 inch doors.
15) What mortise lock should I specify instead for a behavioral health or ligature resistant opening?
The RMB420C uses a continental lever, which is not a ligature resistant trim. For those openings the TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel.
16) Will an InSync battery lock hold up on an outdoor entry door in a cold climate?
The InSync locks are indoor/outdoor approved and rated from -31 F to 151 F (-35 C to 66 C), so a northern exterior lobby or a pool gate is inside the operating range. Power is 4 AA batteries. Keep the emergency lock power supply on the truck, because a dead battery on an unwired exterior door is the one that leaves you outside the building.
17) Is the Continental lever on the InSync lock ADA compliant?
The InSync M and L models use ADA-compliant levers and thumbturns, and the Continental lever is a lever trim, which is the operable-without-grasping shape ADA calls for on the door. The lock is a complete lever set with single motion egress, so one pull on the inside lever gets you out.
18) Do I need a wired connection or a panel to use an InSync lock on a lobby door?
No panel and no wiring to the door. The battery operated InSync locks are standalone at the opening; access data moves in and out on the InSync key rather than over a network. That is the tradeoff to understand before you spec it: no home run to a head end, but also no live lockdown or real-time monitoring at that door. If you need wired power at the lock, the InSync RAC and CP products are also available as hard-wired AC/DC electrically powered devices. On the wired side, comparables include the BEST 45HW electromechanical mortise lock with 12V/24V operation and the Command Access ML190 motorized mortise lock with field selectable EL/EU operation on 24VDC.
19) What is a simpler alternative to an electronic mortise lock for an amenity or utility door that does not need credential control?
The RMB420C is an electronic lock managed through credentials rather than keys alone. If the opening only needs a mechanical function, the Cal-Royal NM8080 is a Grade 1 heavy duty storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors, and the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever. For a utility door that stays unlocked, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors.
20) I need an electronic mortise lock for an apartment or dorm entry rather than a common area door. What are my options?
The RMB420C is configured for common area and utility use. For residential and dormitory style openings, the Schlage Electronics LEBMB-ADD is a Grade 2 mobile enabled mortise lock with push button and LED covering privacy, office, and apartment functions on 1-3/4 inch doors with a 3 hour fire rating. The Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile enabled deadbolt, right hand, also 3 hour fire rated. For a mechanical corridor or dormitory door, the Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt.
21) What keypad mortise lock can I use if I do not want to run RFID credentials?
The RMB420C is credential driven at the door. Keypad alternatives include the Alarm Lock DL3500CR Trilogy, a Grade 1 electronic mortise lock with 300 user codes in a classroom function for 1-5/8 to 1-7/8 inch doors, and the Alarm Lock DL2700CR Trilogy T2 electronic mortise lock, Grade 1 classroom function with a weatherproof design over the same door thickness range. The BEST 45HZ EZ Series is an electronic keypad mortise lock with a key override function.
22) Which mortise products look like substitutes for a battery operated InSync mortise lock but will not do the same job?
Several mortise catalog items sit close by name but are not a complete electronic lockset. The Sargent 130KB and 130W are mortise thumbturns, standard duty trim pieces rather than lock bodies. The BEST 45HCAC and 45HCAINL are mortise lock bodies only, heavy duty, in public entrance and intruder functions, supplied without electronics or trim. The Schlage L0170 is a half dummy trim, a Grade 1 non-keyed lever with no latching function, and the Emtek 3102 Memphis and 3104 Hamilton mortise entrance locksets are dummy function as well. The Falcon MESC600DT is dummy escutcheon lever trim for M9900 Series exit devices.
23) Is an electronic mortise deadbolt an alternative to the RMB420C on a utility door?
The RMB420C is a utility mortise configuration with no deadbolt, so the lever set alone controls the opening. If the door instead calls for a standalone deadbolt under electronic control, the Alarm Lock DL4500 Series is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for 1-5/8 to 1-7/8 inch doors. Mechanically, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset and the Kaba Ilco 185 Series is a mortise deadbolt with no handing.
24) What Grade 1 mortise lock can I standardize on across a facility if I want one mechanical family for classrooms, offices, and privacy doors?
The RMB420C covers a common area opening on its own electronic system. For a single mechanical family across a building, the Cal-Royal NM series runs Grade 1 heavy duty on 1-3/4 inch doors across functions: NM8050 office/entrance with auxiliary deadlatch, NM8070 classroom with auxiliary deadlatch, NM8080 storeroom with interchangeable core option, and NM8440 privacy/bed/bath with deadbolt. The Hager 3800 Series covers passage with the 3810S rose and 3810E escutcheon on a 2-3/4 inch backset, office with the 3850E, and privacy with the 3840S.
25) My door is thinner than 1-3/4 inch. Which mortise locks are listed for that?
Mortise peers vary in the door thickness they accept. The Baldwin 6310 entry/storeroom knob by knob mortise lock body with 2-1/2 inch backset is listed for 1-3/8 inch and over, while the Baldwin 6301 entry/apartment lock bodies are listed for 1-3/4 inch and over. The Alarm Lock Trilogy DL2700CR and DL3500CR cover 1-5/8 to 1-7/8 inch. For ornamental iron doors, the Marks USA 21AC and 22AC entrance double cylinder mortise locks are listed at 1 inch.
26) What finish does the RMB420C InSync mortise lock come in?
Satin chrome, BHMA 626. That is the standard commercial finish, so it will sit next to 626 exit devices, closers and cylinders on the rest of the building without an obvious mismatch. Across the InSync range dormakaba listed satin chrome, satin brass, bright chrome, bright brass, dark mahogany and satin nickel, but this particular lock is built in satin chrome.
27) Is this a residential lock or is it built for commercial traffic?
Commercial. The InSync ASM mortise is a mortise lock body, which is the heavier of the two common commercial formats compared to a cylindrical lock, and it is specified for perimeter entries and amenity doors in multifamily and student housing where traffic is constant. It is not a residential grade tubular lock.
