Alarm Controls 600S Electromagnetic Lock - For Single Door - 600 lbs Holding Force

The Alarm Controls 600S is a single-door electromagnetic lock (maglock) rated at 600 lbs of holding force. A maglock secures a door with magnetism rather than a bolt: an electromagnet mounts on the frame, an armature plate mounts on the door, and when the magnet is energized it holds the door shut with the full 600 lbs of force. Cut power and the door releases instantly, which is what makes a maglock the standard choice for access-controlled and fail-safe openings. The 600S works with any access control system, installs without special tools, and is UL and Canadian UL listed under R16759.

How the 600S works on an access control door

This is the core of why you'd specify a maglock. The 600S holds the door locked only while it has power, so it ties directly into a card reader, keypad, request-to-exit device, or fire alarm. Present a valid credential (or trigger the exit button or fire system) and power drops for an instant, releasing the door, then it re-energizes and holds again when the door closes. Because it releases the moment power is cut, the 600S is inherently fail-safe, which is exactly what egress codes require on many doors: lose power and people can always get out.

The 600S features instant release with no hysteresis, meaning it lets go cleanly and immediately with no residual magnetism dragging the release. That matters for reliable, fast egress. It also has built-in arc suppression to protect the circuit and connected electronics from voltage spikes when the magnet de-energizes.

Built for easy install and reliable service

The 600S is designed to go in fast. The ACC E-Z mount system installs without special tools, using the included self-drilling TEC screws, and the lock works on 12 or 24 VDC, switch selectable, so it matches whatever your access control power supply provides. Current draw is low at 400 mA on 12 VDC or 200 mA on 24 VDC, which keeps power supply sizing simple. Non-aluminum parts are plated to resist corrosion, the body is clear anodized aluminum (US28), and it carries a limited lifetime warranty. The operating temperature range runs +14 to +131F, suitable for typical interior and protected applications.

Why choose the Alarm Controls 600S

Alarm Controls builds dependable, value-priced access control hardware, and the 600S is its workhorse single-door maglock. You get 600 lbs of holding force, clean instant release for reliable egress, built-in arc suppression, low current draw, and the E-Z mount system that gets it installed quickly. It drops into any access control setup, ties into card readers, keypads, exit buttons, and fire alarm release, and the limited lifetime warranty backs it for the long haul. For a standard interior access-controlled door, it's a proven, code-friendly choice.

One thing to confirm before ordering: the 600S is for a single door in an out-swing application with the armature mounted to the door. In-swing doors typically need a Z-bracket, and Alarm Controls offer matching brackets, spacers, and the DJ-1 install template in the same line. If you have a double door, the 600D and 600DLB cover pairs.
