SDC 1511S Series Magnetic Lock with Integrated Activation Sensor, Built-In Key Control, Bond Alert Sensor (BAS), Aluminum

Designed for demanding commercial and institutional environments, the Security Door Controls SDC 1511S magnetic lock delivers high-reliability holding and intelligent monitoring to protect people and assets. This magnetic lock blends 1650 lb holding force with an integrated Activation Sensor and Bond Alert Sensor (BAS) to provide continuous door status and tamper detection — ideal for access control, security, and surveillance systems. The built-in key control and emergency release input let facility managers maintain secure override capability while complying with egress codes.

Installers will appreciate the autosensing 12/24VDC input and ANSI/BHMA Grade 1 construction for consistent performance across single-door applications. Operational flexibility comes from selectable 15/30 second release and an adjustable 1–30 second timed bypass, giving you control over delayed egress behavior without sacrificing safety. With UL and other listings, plus a 5-year limited warranty, the 1511S supports reliable monitoring, reduced nuisance alarms, and seamless integration into your access control infrastructure.
