The SDC Security Door Controls 1575U is a gate electromagnetic lock designed for access control applications requiring secure, fail-safe electric locking. Electromagnetic locks operate by energizing a coil within the lock body to create a magnetic bond between the lock and an armature plate mounted on the gate leaf or door. The 1575U accepts either 12 or 24 volts DC input, making it compatible with a wide range of access control power supplies. It carries a 630 finish designation, which corresponds to a satin stainless steel appearance. This type of device is installed by licensed locksmiths, security system integrators, and access control technicians.
The 1575U is suited for gate and door applications in commercial, industrial, and multi-tenant residential settings. Electromagnetic locks are commonly specified on pedestrian gates, entry doors, and controlled-access points where a fail-safe locking mode is required by code or design intent. Fail-safe operation means the lock releases upon loss of power, allowing free egress. The dual-voltage 12/24 VDC input provides flexibility when integrating with existing access control panels and power supplies.
Designed as an OEM-style electromagnetic lock for gate and door access control systems requiring a 12 or 24 VDC fail-safe electric lock in a 630 satin stainless steel finish.
Installation should be performed by a licensed locksmith or qualified access control technician. Disconnect and lock out all power to the access control panel before wiring the lock. Proper armature plate alignment is critical to achieving rated holding force — verify gate or door alignment before final mounting. Local fire and building codes may govern fail-safe versus fail-secure locking requirements; consult the authority having jurisdiction before installation.
