SDC 1561TJV – Frequently Asked Questions

1) What door types can the SDC 1561TJ electromagnetic shear lock be installed on?
Hollow metal, wood, and Herculite glass doors. It's a commercial, heavy duty unit, and the aluminum-bodied housing surface mounts at the top jamb rather than needing a mortise pocket cut into the door or frame.
2) Does the SDC 1561TJ shear lock unlock when the power goes out?
Yes, it's fail-safe. Kill the 12/24VDC supply and the lock releases, which is what a life safety or fire alarm interface requires for egress. If your spec calls for the door to stay locked on power loss, this is the wrong device.
3) Can I put a shear lock on a fire rated door assembly?
The 1561TJ is certified to the UL 10C positive pressure fire test and is ULC-S104 compliant, so it can go on fire rated door assemblies. That, combined with fail-safe release, is why it shows up on healthcare and school openings where the door has to both hold and drop out on alarm.
4) My doors are slightly out of alignment and have uneven gaps. Will a shear lock still bond?
That's the case the HiShear design targets. The floating armature assembly with alloy steel locking tabs adjusts vertically and laterally to take up door gap and misalignment, and a door alignment relock sensor in the electronics confirms the door is positioned correctly before the lock re-engages. On a sagging or racked opening that's the difference between a lock that bonds every time and one that reports a fault.
5) What options do I have to specify when ordering an SDC 1561TJ shear lock?
Four choices on the order. Bond Alert Status (BAS), which reports whether the lock is actually bonded rather than just powered. Door Position Switch (DPS), for monitoring open or closed at the head. Visual Status Indicator (LED) on the housing. And finish. Each of the three monitoring options is a yes or no, so pick them against what your access control panel has inputs for; adding them later means pulling the unit.
6) How do I know whether the shear lock is actually locked and not just powered up?
Order the 1561TJ with the Bond Alert Status option. BAS reports true bond rather than just coil power, which is the distinction that catches a door sitting misaligned or held slightly open. Pair it with the Door Position Switch if you also want open/closed state at the panel, and with the LED option if you want a technician to read status at the door without a laptop.
7) Which shear lock works on an in-swing door without a Z bracket?
The SDC HiShear 1561TJ mounts surface at the top jamb, which is what removes the Z bracket normally required to reach the pull side of an in-swing door with a magnetic lock. The Schlage GF3000 is a mortise mounted shear lock, so it solves the same pull-side problem by sitting inside the door and frame rather than on the surface. If the opening is existing and you are not prepping the door, the surface top jamb approach of the 1561TJ is the one that installs onto what is already there.
8) Is a mortise shear lock like the Schlage GF3000 a drop-in replacement for a surface mounted SDC 1561TJ?
No. The Schlage GF3000 is a mortise mounted shear lock, and the SDC HiShear 1561TJ is surface mounted at the top jamb. They are both shear locks and both heavy duty, but they occupy the opening differently: swapping a surface top jamb unit for a mortised one means machining a pocket in the door or frame that the surface unit never needed, and the surface unit's mounting holes do not correspond to a mortise cutout. Plan a mortise-to-surface or surface-to-mortise change as a door prep job, not a hardware swap.
9) What finishes does the SDC 1561TJ shear lock come in?
Six: 335 dull black, 605 bright brass, 625 bright chrome, 626 dull chrome, 628 dull aluminum, and 710 dark bronze. If you're standardizing a building, 626 and 628 are the ones that disappear against typical aluminum and hollow metal frames, and 710 matches dark bronze storefront.
