SDC Security Door Controls EP493 Explosion Proof Pull Station

Overview

The SDC EP493 is an explosion-proof pull station controller designed for hazardous environments requiring certified access control functionality. It supports NFC/13.56MHz credential reading with proximity and keypad input options, making it suitable for industrial and chemical facility installations where standard controllers cannot operate safely.

Compatibility

The EP493 communicates via OSDP (Open Supervised Device Protocol), ensuring vendor-neutral integration with enterprise access control systems. Operates at 30VDC, compatible with standard 24-30VDC power distributions common in hazardous-location installations. Integrators should verify explosion-proof enclosure certification requirements for specific deployment environments and local jurisdictional standards.
