Professional Semi-Concealed Electromagnetic Security Solution

The SDC HiShear 1562SC Series electromagnetic shear lock delivers superior security with 2000lb holding force and fail-safe operation for commercial applications. This semi-concealed design features 12/24VDC auto-sensing dual voltage input and mounts on the secure side of the door opening to eliminate tampering potential. Built with floating armature assembly and special alloy steel locking tabs, this heavy-duty electromagnetic lock provides adjustable vertical and lateral alignment to compensate for door gaps and misalignment.

Professional Features & Benefits

  • High Security Holding Force: 2000lb holding capacity provides exceptional security for commercial-grade hollow metal, wood doors, and Herculite doors with top rails.
  • Semi-Concealed Mounting: Surface mount design with concealed electromagnetic lock and surface mounted armature assembly for enhanced security and architectural appearance.
  • Flexible Power Options: Auto-sensing dual voltage 12/24VDC input eliminates the need for voltage selection switches and simplifies installation.
  • Fail-Safe Operation: Fail-safe locking mechanism ensures doors unlock during power loss for emergency egress compliance.
  • Advanced Alignment System: Floating armature assembly with special alloy steel shear tabs adjustable both vertically and laterally compensates for wide door gaps and warped or misaligned doors.
  • Smart Door Monitoring: Door alignment relock sensor with advanced electronic circuitry ensures proper door positioning and secure locking.
  • Noise Reduction Technology: Integrated noise dampeners greatly reduce locking and unlocking sounds compared to standard shear locks.
  • Fire Safety Certified: UL 10C Positive Pressure Fire Tests certified and ULC-S104 compliant for fire-rated door assemblies.

SDC 1562SCV – Frequently Asked Questions

1) Will an SDC 1562SC shear lock work on a 1/2 inch frameless glass door?
Yes, but you have to order the right model. The 1562SC family splits three ways: the base 1562SC for standard doors, the 1562SCHDB for 1/2 inch glass doors, and the 1562SCHDB3/4 for 3/4 inch glass. All three are semi-concealed with external electronics and 2000 lbs of holding force. Pick the glass thickness variant that matches the door, because the standard 1562SC is not the glass-door version.
2) What happens to an SDC HiShear 1562SC when the building loses power?
The door unlocks. The 1562SC is fail-safe, so the magnet drops out on power loss and the opening is free for egress. That is the behavior you want on an egress door tied to a fire alarm relay, and it is the behavior you do not want on a door that must stay secure through an outage, so if the opening needs to hold locked without power, a shear lock of this type is the wrong choice.
3) Can an electromagnetic shear lock be used on a fire-rated door?
The SDC HiShear 1562SC is certified to UL 10C Positive Pressure Fire Tests and compliant with ULC-S104, so it is cleared for fire-rated door assemblies. That is the distinction that matters against a typical surface magnetic lock: the shear lock mounts into the head of the opening and does not sit proud on the face of the door, which is why it can be listed for a fire door.
4) Do I need a 12V or 24V power supply for the SDC 1562SC shear lock?
Either one. The 1562SC is auto-sensing dual voltage, 12/24VDC, so it detects the input and there is no jumper or selector switch to set. Wire it to whatever DC supply the access control panel already provides on that opening. It is not battery operated, so it needs a permanent DC source.
5) My doors are warped and the gaps are inconsistent. Will a shear lock still latch?
That is the case the 1562SC is built for. The armature floats and the alloy steel shear tabs adjust both vertically and laterally, so you can take up wide door gaps and warped or misaligned leaves at install instead of rehanging the door. A door alignment relock sensor confirms the leaf is sitting where it should before the lock re-engages, so it will not try to shear-lock a door that is out of position.
6) What do I have to specify when ordering an SDC 1562SC shear lock?
Four choices. Model (base 1562SC, 1562SCHDB for 1/2 inch glass, or 1562SCHDB3/4 for 3/4 inch glass), finish, whether you want a door position switch, and whether you want the visual status indicator LED. The DPS gives your access control panel a real door status contact, and the LED gives the installer and the user a visible locked/unlocked state at the opening. Both are ordered-in options, not field additions, so decide them before the order goes in.
7) Can the Schlage GF3000 be used as a drop-in replacement for an SDC 1562SC shear lock?
No. Both are shear locks and both are heavy duty, but they are prepped differently: the SDC 1562SC is a semi-concealed unit with a surface mounted armature assembly, while the Schlage GF3000 is mortise mounted. Swapping one for the other means changing the door and frame preparation, not just the lock body. If the existing opening was prepped for a semi-concealed HiShear, staying within the 1562SC line - including the 1562SCHDB and 1562SCHDB3/4 glass door versions for 1/2 inch and 3/4 inch glass - keeps the existing prep usable.
8) What kind of doors can a 2000 lb shear lock be installed on?
Commercial hollow metal, wood doors, and Herculite glass doors with a top rail all take the 1562SC. For frameless glass without a top rail you need the HDB models cut for 1/2 inch or 3/4 inch glass. It is a heavy duty commercial product, not a residential one.
9) Can I get door status monitoring back to my access control panel from an SDC 1562SC?
Order it with the door position switch option and the lock reports door position to the panel. Separately, the visual status indicator LED is an at-the-door display of lock state. They are two different options and you can take either, both, or neither, so if the panel needs a monitored contact, the DPS is the one to specify.
10) What finishes does the SDC HiShear 1562SC come in to match the rest of my door hardware?
Six: 335 dull black, 605 bright brass, 625 bright chrome, 626 dull chrome, 628 dull aluminum, and 710 dark bronze. Those are standard BHMA finish numbers, so 626 and 630 hardware families in the building are easy to sit next to. The body is aluminum.
11) Are shear locks noisy when they release?
Standard shear locks make an audible clack on lock and release. The 1562SC has noise dampeners built into the assembly that cut that sound considerably, which is the reason it gets specified on patient rooms, libraries, and hotel corridors where a hard mechanical snap every time someone badges through is a complaint waiting to happen.
