SDC HiShear 1560 Series Concealed Electromagnetic Shear Lock

The SDC HiShear 1560 Series concealed electromagnetic shear locks deliver superior security with 2,000 lb and 2,700 lb holding force options for commercial applications. Featuring a patented floating armature assembly with special alloy steel locking tabs, these fail-safe locks accommodate standard 1‑3/4" to 2" frames with integrated electronics and narrow 1‑1/4" to 1‑1/2" frames with external electronics. Auto-sensing dual voltage 12/24VDC operation with door alignment relock sensor ensures reliable performance for demanding commercial installations.

Features & Benefits

  • High Holding Force Options: Available in 2,000 lb (models 1561/1562) and 2,700 lb (models 1565/1566) configurations for maximum security.
  • Patented HiShear Floating Armature: Special alloy steel locking tabs provide superior durability and adjustability for misaligned doors.
  • Flexible Frame Compatibility: Integrated electronics for standard 1‑3/4" to 2" frames; external electronics for narrow 1‑1/4" to 1‑1/2" frames.
  • Auto-Sensing Dual Voltage: 12/24VDC operation with automatic voltage detection simplifies installation and system integration.
  • Door Alignment Relock Sensor: Ensures the lock re-engages only when the door is properly aligned, preventing false-secure conditions.
  • Noise Reduction Technology: Built-in noise dampeners significantly reduce locking and unlocking sounds versus standard shear locks.
  • Adjustable Alignment System: Vertical and lateral adjustment compensates for door gaps and warped or misaligned doors.
  • Fire-Rated: UL 10C positive pressure fire test certified and ULC compliant for code-compliant installations.

SDC 1566ITC – Frequently Asked Questions

1) What does the shear lock do on a power failure, and can I use it on an egress door?
The 1560 Series is fail-safe: cut power and the lock releases. That is the behavior code officials generally expect on an egress opening, and it is why a shear lock like this is tied into the fire alarm and access control rather than left standalone. If your application calls for the door to stay locked when power drops, this is the wrong device entirely.
2) Is the SDC 1560 shear lock fire rated?
Yes. The HiShear 1560 Series is UL 10C positive pressure fire test certified and ULC compliant, which is what lets it go on a labeled opening. That certification is a big part of why a concealed shear lock gets specified over a surface magnet on a fire door.
3) Which shear lock should I use on a fire rated door in a hospital corridor?
The SDC HiShear 1560 Series is UL 10C positive pressure fire test certified and ULC compliant, and it is fail safe, so it releases on power loss as egress and fire alarm interface generally require. It runs 12/24VDC with auto sensing, which lets it sit on either common supply voltage in an existing panel. For an institutional buyer standardizing a fire rated opening across a facility, those are the attributes to confirm on any alternate shear lock before substituting.
4) Should I use a concealed shear lock or a surface mounted electromagnetic lock?
A shear lock mortises into the header and the door top, so nothing shows when the door is closed. That is the reason to pick it: appearance on a glass or architectural opening, and a fire label the UL 10C certification supports. The tradeoff is prep. A surface mag needs no machining and tolerates sloppy openings; the 1560 needs a mortise pocket in the frame and the right armature channel in the door. The 1560 does answer the usual shear lock complaint about warped doors with vertical and lateral adjustment and a door alignment relock sensor that keeps it from reporting secure when the door is not actually seated.
5) Can I get door position and lock status monitoring on the SDC 1560?
Three monitoring options are ordered as suffixes, each independently yes or no: a door position switch, bond alert status (which reports whether the magnet is actually holding, not just energized), and a visual LED status indicator. Specify them at order time. If your head end needs a secure signal and a separate door open signal, take both the bond alert and the DPS.
6) Will a shear lock hold a warped or misaligned door?
That is the specific problem the HiShear design addresses. The floating armature assembly uses alloy steel locking tabs with vertical and lateral adjustment to take up door gap and warp, and the relock sensor only lets the lock re-engage once the door is aligned, so you do not get a false secure reading. Built-in noise dampeners also cut the clack that surface shear locks are known for, which matters in a healthcare or hospitality corridor.
7) Is 2,000 lbs enough holding force, or should I step up to 2,700?
For most commercial interior and perimeter openings the 2,000 lb models (1561 integrated, 1562 external) are the standard pick. Step to the 2,700 lb 1565 or 1566 on high traffic or high abuse doors where you expect people to pull hard on a locked leaf. Both are heavy duty rated commercial units, so the difference is purely resistance to force, not build class.
8) Is a magnetic lock the same thing as a shear lock?
Not the same install. A shear lock such as the SDC HiShear 1560 Series or the Schlage GF3000 is mortise mounted, concealed into the frame head with an armature in the top of the door, so the lock holds against a shear plane and nothing is visible when the door is shut. A surface magnetic lock hangs on the frame face and holds against direct pull. If the specification asks for concealed hardware, a surface mag lock is not a drop in for either of these shear locks.
9) Do I need a separate door position switch if I use an SDC 1560 shear lock instead of another brand?
The SDC HiShear 1560 Series can be ordered with monitoring built into the lock: a door position switch, a bond alert status output, and a visual status LED are each selectable options on the unit. Specifying them on the lock means the access control head end reads door state and bond condition from the shear lock itself instead of from separately mounted contacts, which is the difference worth checking against any competing shear lock before you buy switches for the job.
10) My existing shear lock keeps failing to relock on a warped door - what should I replace it with?
The SDC HiShear 1560 Series is built for exactly that condition. Its patented floating armature assembly with alloy steel locking tabs adjusts to misaligned doors, vertical and lateral adjustment compensates for door gaps and warping, and a door alignment relock sensor holds the lock from re-engaging until the door is actually aligned, which prevents a false secure reading. A property manager replacing a shear lock that will not consistently bond on a settled frame is buying the adjustment range and the relock sensor.
