STI EP201608-T3 NEMA 3R Filter Fan Tinted Polycarbonate Enclosure
Overview
The EP201608-T3 is a NEMA 3R-rated polycarbonate enclosure with integral filter fan, designed to protect access control electronics and wiring from rain, dust, and temperature fluctuations in outdoor and semi-protected environments. The tinted polycarbonate construction blocks direct sunlight while maintaining visibility of interior components for troubleshooting and maintenance. This unit solves the deployment challenge of mounting readers, keypads, or credential processors in exposed locations without running conduit back to an indoor cabinet — a common scenario at loading docks, parking structures, and building perimeters where compact weatherproof housing is required.
Compatibility
The EP201608-T3 integrates with STI access control reader platforms, button stations, and credential display modules that fit within standard NEMA enclosure envelopes. Consult the specific reader or station datasheet for internal dimensional requirements. The filter fan is sized for small to medium enclosures and works with standard 120V AC power supplies commonly used in access control installations. It is compatible with both wired and wireless reader architectures that mount within polycarbonate boxes.
Installation Notes
Mount the enclosure on vertical surfaces using corrosion-resistant hardware suitable for the mounting substrate (concrete, metal, or composite). The filter fan requires 120V AC power via a dedicated branch circuit or shared low-current access control panel output — verify available amperage before installation. Ensure adequate clearance around the fan intake and exhaust vents to prevent moisture pooling. The tinted polycarbonate is UV-stabilized but will yellow over 5–10 years in direct unobstructed sunlight; consider partial shade or reflective canopy placement for extended life. Drill entry holes for wiring cleanly to avoid stress cracks in the polycarbonate; use rubber grommets at all cable penetrations to maintain the NEMA 3R seal.
