STI EP181611-O EnviroArmour Polycarbonate Controller
The EP181611-O is a polycarbonate-housed access control controller designed for multi-door TCP/IP installations requiring compact, durable mounting in non-metallic environments. Built from injection-molded polycarbonate finished in RAL 7035 (light gray), it handles up to 7 doors per unit and operates at 44dB(A) — quiet enough for occupied spaces without acoustic interference.
Overview
Deploy this controller where you need distributed door management across networked systems without metallic enclosure constraints. The polycarbonate construction provides chemical resistance and impact durability in warehouse, manufacturing, and outdoor weather-exposed areas. UL/cUL certified under EP242410-O, meeting North American electrical and safety codes for access control installations. TCP/IP backend integration enables centralized credential administration and real-time event logging across multiple controller locations.
Compatibility
Integrates with standard credential readers (magnetic stripe, proximity, keypad, biometric) and electric strike hardware within enterprise access control architectures. Designed for multi-door system deployments where individual controller units manage separate door zones on a shared network backbone. Compatible with centralized access management platforms supporting TCP/IP controller polling and credential provisioning.
Installation Notes
Conduit entry holes support standard hub sizes from ½" to 2" diameter; refer to installation guide for hole-cutting specifications and Greenlee punch placement. Metallic conduit requires bonding to grounding bushings per Canadian Electrical Code requirements; non-metallic conduit eliminates grounding bushing requirement but must be aligned to prevent enclosure wall stress. Device mounting plate and ground wire lugs are included for secure hardware attachment and electrical grounding continuity.
