Command Access REX-KIT-ML – Frequently Asked Questions

1) What does the Command Access REX-KIT-ML actually do on a mortise lock?
The REX-KIT-ML is a request-to-exit switch kit for Command Access ML1-Series mortise locks. It adds electronic exit request signaling to a lock that did not have it, so the access control system knows someone is legitimately leaving through the opening instead of reading it as a forced door. It is an electronic component, sold as a replacement part rather than a complete lock.
2) Will the REX-KIT-ML fit a Schlage or Sargent mortise lock I already have in the door?
No. The REX kit is engineered specifically for Command Access ML1-Series mortise locks. If the lock body in your door is another manufacturer's, this kit is not the part for it, and you would need a REX solution matched to that lock body or a separate surface-mounted exit sensor.
3) Do I have to replace the whole mortise lock to add request to exit, or can this be retrofitted?
No lock replacement needed. The kit is field installable, so an existing ML1-Series mortise lock can be upgraded in place. The door and frame prep stays as is, which keeps downtime on an occupied opening short compared with pulling and replacing the lock body.
4) If the mortise lock on the door is not a Command Access ML1-Series, what can provide request to exit instead?
The Command Access REX-KIT-ML is engineered specifically for ML1-Series mortise locks, so it is not the part for a different mortise lock body. For a door where the lock cannot host an internal switch, the DynaLock 6451-36 is an exit sensor bar sized for a 36 inch door, mounted on the door face rather than inside the lock case. That approach gives you an exit signal without touching the existing lock, at the cost of surface-mounted hardware on the push side.
5) Is the RCI 9500/9501 mortise pin transfer an alternative to the Command Access REX-KIT-ML?
No, they do different jobs on the same door. The REX-KIT-ML adds electronic request to exit switching inside an ML1-Series mortise lock. The RCI 9500/9501 is a mortise pin transfer rated 1.5A at 24VAC with a tamper-resistant design, and its role is carrying power and signal across the hinge edge from frame to door. On an electrified mortise opening you may well need both: the transfer to get the wiring into the door leaf, and the REX kit to generate the exit signal.
6) Can a maintenance tech install this, or does it need a locksmith?
It is built for field installation by a qualified technician. The lock body has to come out of the door, be opened, and the switch assembly fitted and wired back through the door loop to the access control panel. A locksmith or security integrator comfortable working inside a mortise case is the right person; a general maintenance hand without those tools usually is not.
7) Is the REX-KIT-ML suitable for a school or hospital access control system?
Yes, it is a commercial-rated component, and the intended applications include healthcare facility access control, educational institution safety systems, government and municipal buildings, retail, and industrial monitoring. For a facility standardizing on ML1-Series mortise locks, this is the piece that brings those openings onto the access control head end without changing the lock hardware.
8) How many versions of the REX-KIT-ML do I need to choose from when ordering?
One. The kit is ordered as a single model, REX-KIT-ML, with no handing, finish, or voltage variations to specify. What you do need to confirm before ordering is that the lock in the door is an ML1-Series mortise lock, since that is what the kit is cut for.
9) What should I use instead if I need request to exit but the door has a mag lock or no mortise lock at all?
A lock-internal REX switch only works where there is an ML1-Series mortise lock to put it in. On a mag-locked opening or a door with no mortise case, use a separate egress device instead: a DynaLock 6451-36 exit sensor bar for a 36 inch door gives touch-sensing egress off the push bar, and a Dortronics 6500 Series pull station or 5000 Series push button, which the 6510/COV anti-tamper cover fits, covers a manual release point.
10) What else do I need to order to get the REX signal from the door to the panel?
The kit supplies the switch inside the lock; the wiring path and power still have to be handled. On a mortise lock, the usual transfer is a concealed mortise pin transfer such as the RCI 9500/9501 Series, rated 1.5A at 24VAC, to carry the conductors from frame to door. If the panel side needs additional dry-contact outputs, a relay board like the Locknetics RDB4 four-output relay distribution board handles distribution.
11) Will adding this kit change how the door opens in an emergency?
No. Request to exit is a monitoring and signaling function, not a locking function. The mortise lock still allows free egress by turning the inside lever; the kit simply reports that the lever was operated so the access control system shuts down the alarm and releases any interlocked device. Egress behavior of the lock itself is unchanged.
12) We need to know when someone leaves through a delayed egress door, not just signal the access control panel. Is the REX kit the right part?
The REX-KIT-ML is a request to exit switch kit for ML1-Series mortise locks; it reports exit intent to an access control system but does not itself annunciate. For audible local warning on a delayed egress opening, the RCI 914 Series is a delayed egress sounder with field-selectable volume up to 102dB, and the Adams Rite 29-0218 is a piezo electric horn with multi-voltage compatibility. Those handle the alarm side while the REX kit handles the signal side.
13) Does the Command Access REX-KIT-ML include power or relay output for the access control circuit?
The REX-KIT-ML is a field-installable switch kit that adds electronic request to exit capability to an ML1-Series mortise lock. Power and relay logic are separate components in an access control system: the Adams Rite 4605 is a transformer taking 115 VAC to 12/24 VAC with 40 volt-amp output, and the Locknetics RDB4 is a four-output relay distribution board. Plan the power supply and relay board alongside the REX kit rather than expecting them in the kit.
14) What is the difference between the REX-KIT-ML and a push button or pull station release at the door?
The REX-KIT-ML generates the exit signal from the lock itself, so a normal turn of the lever on an ML1-Series mortise lock is what releases the door and the exit is not logged as a forced door. A button or pull station is a deliberate separate action by the person leaving; Dortronics offers the 6510/COV anti-tamper alarm cover for its 6500 Series pull stations and 5000 Series push buttons where that style of release needs protection from misuse. Choose the in-lock kit when you want egress to feel like ordinary lever operation.
15) Will the Command Access REX-KIT-ML work on an all-glass or herculite door?
The REX-KIT-ML is built to retrofit into ML1-Series mortise lock bodies, which assumes a door prepped for a mortise lock case. All-glass openings use their own mounting hardware family, such as the Securitron Glass Door Accessories, listed at Grade 2. For a glass front, specify hardware from that glass door line rather than a mortise lock retrofit kit.
16) Is a proximity card or tag an alternative to the REX kit?
No. Credentials such as the DynaLock 7551 Series proximity card and 7561 Series proximity tag control entry on the secure side. The Command Access REX-KIT-ML works on the egress side, signaling the access control system that someone is leaving through an ML1-Series mortise lock. A typical commercial opening uses both: a reader and credentials to get in, a request to exit device to get out without a forced-door alarm.
