SDC Z7835RRCQ – Frequently Asked Questions

1) Will the SDC 7835 latch into my existing ANSI strike, or do I have to change the frame prep?
The 7835 uses the standard ANSI 4-7/8 inch strike and throws a 3/4 inch latch, so an existing frame already prepped to ANSI 4-7/8 takes it without cutting. Face plate measures 81/32 x 15/16 x 7/32 inches. If your frame carries a T-strike or a non-ANSI cutout, the frame is the work item, not the lock.
2) Can I use an electrified mortise lock like the SDC 7835 on a fire rated door instead of a maglock or electric strike?
That is the main reason to pick it. The 7835 stays latched even when it is unlocked, so fire door integrity is maintained and you do not hang an exposed electric strike or magnetic lock on the opening. It carries UL 10C and ULC-S104 fire test certification with CSFM listing 3774-0324:0104. A maglock releases the door entirely on power loss, which is a different code conversation; this keeps the latch in the strike and only controls the lever.
3) Does the SDC 7835 fail secure or fail safe, and can I set it in the field?
Both, and yes. The 7835 ships fail-secure outside and fail-safe inside, and the fail-secure/fail-safe operation, handing, and function are all field-reversible. So a stair tower that must lock out but always allow egress side free is set at the door rather than reordered. Handing is also an ordering axis (LH, LHR, RH, RHR) if you want it correct out of the box.
4) Is the SDC 7835 mortise lock 12V or 24V?
Standard operation is 24VDC, and it is orderable at 12 VDC or 24 VDC. The unit is also field-selectable dual voltage, so it drops onto an existing 12V access control power supply without a separate step-down. Size your supply for the solenoid inrush the same way you would any electrified mortise body.
5) What monitoring options do I have to order with the SDC 7835 for my access control panel?
Three monitoring options are specified at order: request-to-exit (REX), door position status (DPS), and latch status (LS), each a yes or no on the order. Switching is SPDT. If your panel needs to know the door actually closed and relatched, take DPS and LS together; REX alone only tells the panel someone turned the inside lever. These are not field-addable afterthoughts, so decide them with the panel integrator before the order goes in.
6) Can the SDC 7835 replace an existing mechanical mortise lockset in my building?
Yes. The 7835 replaces most brands of mechanical locksets, which is what makes it a retrofit rather than a door replacement. The prep it wants is a standard 1-3/4 inch door with 2-3/4 inch backset and an ANSI 4-7/8 inch strike, so if the existing opening is a conventional commercial mortise prep the body drops in and the work becomes getting power to the door.
7) What is an equivalent to the SDC 7835 mortise lock if I need a motorized rather than solenoid electrified mortise lock?
The SDC Selectric 7835 PRO Series is a solenoid controlled electrified mortise lock running on 24VDC, with fail-secure outside and fail-safe inside operation. If the opening calls for a motorized drive instead, the Command Access LPM190-M-EU-CH is a 24V motorized mortise lock with electric unlock and optional request-to-exit, in storeroom function. Both are heavy-duty electrified mortise locks; the difference is the drive method and that the SDC 7835 offers field-reversible fail-secure/fail-safe selection while the LPM190-M-EU-CH is a storeroom function unit.
8) I need latch retraction rather than electric unlock on a mortise lock - what should I use instead of the SDC 7835?
The SDC Selectric 7835 PRO Series uses a solenoid to control locking, with a mortise cylinder for manual latch retraction, and it keeps the latch projected even when unlocked so fire door integrity is maintained. If the application requires the latch itself to retract electrically, the Command Access LPM110ECH is a heavy-duty electrified latch retraction mortise lock chassis operating on 24VDC. Electric latch retraction pulls the latch back, which is a different behavior from the SDC 7835 unlocking the trim while the latch stays engaged.
9) Which electrified mortise lock should I specify for a psychiatric or detention-type opening instead of the SDC 7835?
The SDC Selectric 7835 PRO Series is configured fail-secure outside and fail-safe inside, so the inside lever releases on power loss - that is the wrong behavior for an opening where the inside must stay controlled. For asylum, institution, or utility function, the Command Access ML04EU is a heavy-duty electrified mortise lock chassis built specifically in Asylum/Institution/Utility function, which keeps both sides key or credential controlled.
10) For a fire-rated door, does the SDC 7835 work where a Command Access LPM110ECH latch retraction lock would not?
The SDC Selectric 7835 PRO Series maintains fire door integrity by staying latched even when unlocked, and carries UL 10C and ULC-S104 fire test certifications with CSFM listing 3774-0324:0104. The Command Access LPM110ECH is a heavy-duty electrified latch retraction mortise lock chassis, which by design pulls the latch back when energized. On a fire-rated opening, positive latching is the governing requirement, so verify latch behavior against the door's fire listing before specifying an electric latch retraction device.
11) Is the SDC 7835 Grade 1, and will it hold up in a high traffic school or hospital corridor?
It is a Grade 1 heavy-duty mortise lockset built to ANSI A156.13, the mortise lock standard, and it is a commercial-only product. For abuse-prone openings it uses a vandal-resistant clutch, so a lever that gets hung on or forced when locked spins rather than transmitting the load into the hub. That is the failure mode that kills locks in schools and behavioral health corridors.
12) What finishes does the SDC 7835 come in, and can I match the existing hardware on my other doors?
Nine BHMA finishes: 605 bright brass, 606 dull brass, 611 bright bronze, 612 dull bronze, 613 oil rubbed bronze, 625 bright chrome, 626 dull chrome, 629 bright stainless, and 630 satin stainless steel. Most commercial buildings standardized on 626 dull chrome or 630 satin stainless, so if you are matching a corridor of existing levers check the small BHMA number stamped on the current trim and order to it.
13) Should I use a solenoid electrified mortise lock or a motorized one for my access control doors?
A solenoid unit like the SDC 7835 holds a coil energized to change state, which is simple and fast but draws current the whole time it is unlocked, so it wants a continuous-duty supply sized for the door count. A motor-driven mortise lock such as the Command Access LPM190-M-EU-CH draws only during the transition. If you are unlocking a lobby door for eight hours on a schedule, the motorized approach is easier on the power supply; for short momentary releases on a card read, the solenoid design is straightforward and there is less to go wrong.
14) What is the difference between the SDC 7835 and a plain mechanical mortise lock like the Schlage L9050?
The Schlage L9050BDC is an entrance/office function mechanical mortise lock, Grade 1 heavy duty, for 1-3/4 inch doors, with no electrical control at all. Someone changes its state with a key or a thumbturn. The 7835 is the electrified version of that same opening: 24VDC solenoid control that lets a card reader or panel lock and unlock the lever remotely, with a key cylinder still available for manual override. If the door does not need to be on the access control system, the mechanical lock is the simpler buy.
15) I need an electrified mortise lock for a patient room or holding area, not a normal office door. Is the SDC 7835 right?
For asylum, institutional, or utility function, where the inside lever has to be controlled differently than a standard office door, the Command Access ML04EU is the chassis built for that function. The 7835 is a fail-secure outside, fail-safe inside arrangement, which suits perimeter and corridor doors where the egress side must always release. For a straight storeroom function electrified chassis, the Command Access ML1080LB or the DynaLock EML-1 cover that.
16) Does the SDC 7835 do electric latch retraction so I can tie it to a card reader for free entry?
No. The 7835 controls the lever, not the latch, and it stays latched when it is unlocked, which is what preserves fire door integrity. If you need the latch itself pulled back electrically so the door pushes open with no hardware operation, that is a latch retraction chassis, not this. The Command Access LPM110ECH is an electrified latch retraction mortise chassis running on 24VDC.
17) Is a Command Access ML1080LB a substitute for the SDC 7835?
No. The Command Access ML1080LB is a heavy-duty storeroom function mortise lock chassis - a mechanical chassis, not an electrically controlled one. The SDC Selectric 7835 PRO Series is an electrified mortise lock operating on 24VDC with SPDT monitoring and optional request-to-exit, door position status, and latch status signalling, so it can be locked, unlocked, and monitored from an access control panel. If the ML1080LB is being replaced on a door that is now being brought onto access control, the 7835 is the upgrade path; if the door stays mechanical, the ML1080LB stays a mechanical chassis.
18) What is a simpler storeroom-function electrified mortise lock alternative to the SDC 7835?
The DynaLock EML-1 Series is an electrified mortise lock in storeroom function - one fixed function, outside lever locked and key or credential controlled, inside lever always free. The SDC Selectric 7835 PRO Series covers a broader configuration range instead: field-reversible fail-secure/fail-safe operation, field-selectable handing and function, four handings, 12 VDC or 24 VDC, and optional REX, door position status, and latch status monitoring. Where the opening only ever needs storeroom behavior, the EML-1 is the narrower spec; where the function may need to be set or changed in the field, the 7835 carries that flexibility.
19) Can I use a Command Access mortise lock chassis in place of a complete SDC 7835 lockset?
They are not the same scope of supply. The Command Access LPM110ECH, ML04EU, and ML1080LB are mortise lock chassis - the working body that goes into an existing mortise pocket. The SDC Selectric 7835 PRO Series is ordered as a complete lockset: chassis plus a trim selection in rose or escutcheon styles including Eclipse, Galaxy, Nova, and Schlage 07, an optional CYL-6KAQ or CYL-6KDQ mortise cylinder, and a finish from 605 bright brass through 630 satin stainless steel. If existing trim and cylinder are being reused, a chassis is the matching purchase; if the door is being outfitted complete, the 7835 covers trim and cylinder in one order.
