Installation Instructions

GoKeyless is a trained and authorized Schlage® dealer. Sales, service, and support. It's why thousands of clients around the world choose GoKeyless™ for their security and access control needs each year. The Schlage M490G electromagnetic gate lock is a weather resistant electromagnetic lock with 1500 lbs of holding force, designed for use on all types of sliding and swinging gates. As a high security magnetic lock, it can accommodate misalignment problems while supplying superior holding force. A 1/2" compression connector is provided for installation of 1/2" EMT conduit, insuring protection of hook-up wiring from weather and vandalism. Heavy-duty plating resists corrosion of mating surfaces, providing a low maintenance locking device. A modified top jamb mounting bracket allows a single M490G to be mounted in a variety of positions. The M490G gate lock may be mounted to any gate frame or post. Special brackets may be required to adapt the lock to a particular frame or post. It is important that the lock is mounted so that the armature pulls straight back from the magnet face. The M490G can be field configured for either 12 or 24 VDC operation. Magnetic Bond Sensor (MBS) and Gate Status Monitor (DPS) are standard.

Customer Questions & Answers

  1. A

    This would entirely be based on the system that the maglock is wired to. The maglock has no remote capabilities on its own.

  2. A

    All electromagnet locks are inherently fail-safe. If an electromagnetic lock loses power, the door will unlock as the magnet is no longer energized. The only way to keep the door secure would be to have an additional backup power supply for the device. 

  3. Q Does this lock support fail-secure, i.e, stays locked if power is cut ? answer now
    Asked by Chris Ferraro on June 17, 2020 12:00 AM

    This lock does support fail-secure but you would need an additional backup power supply. If the lock has no power, the magnet will not remain locked.
