Comelit UT9174B Surfaced-Mounted Housing 4 Ultra Module
Overview
The Comelit UT9174B is a wall-mounted housing designed to hold four ultra modules in distributed surveillance and access control installations. This is your solution when you need a compact, flush-mount enclosure for multi-sensor or modular configurations—typical in entrance security, building lobbies, or mixed-sensor array deployments where space and aesthetics matter. The UT9174B measures 110 × 380 × 35 mm, projecting only 35 mm from the wall, which keeps the installation visually integrated and reduces snag hazards in high-traffic areas.
Compatibility
The UT9174B is engineered for Comelit Ultra module ecosystems. It supports PoE power delivery, making it suitable for thermal imaging modules, multi-sensor arrays, and standard entrance panel configurations that operate within the Comelit Ultra product family. Integrators deploying mixed sensor types (e.g., thermal + visible light, or modular audio/video combinations) should verify that each module is Ultra-series compatible before specifying this housing.
Construction and Durability
The housing consists of a metal support frame (which secures modules without screws) and a die-cast aluminum finishing frame treated with cataphoresis coating. Cataphoresis treatment significantly improves resistance to chemical attack, environmental corrosion, and UV degradation—meaningful if the housing faces direct sun exposure, salty air, or industrial exhaust environments. The minimal 35 mm protrusion reduces weather intrusion compared to deeper housings, though you'll still want proper drainage design around the perimeter in high-rain exposures.
Installation Notes
Wall-mounted installation requires standard masonry anchors or wood fastening appropriate to your substrate. The compact form factor and shallow depth simplify rough-in work in retrofit applications. Verify that your PoE switch or injector supplies adequate wattage for all four modules combined before final commissioning. No special tools or torque specifications are required for module insertion into the support frame.
