Honeywell Analytics / Vulcain E3SM E3Point Gas Monitor without Sensor, Wall Mount, Modbus/BACnet

The Honeywell Analytics / Vulcain E3SM E3Point gas monitor base delivers dependable, network-ready gas detection for industrial and commercial safety monitoring. As a wall-mount detector base (sold without sensor), the E3SM lets facilities teams deploy the exact sensor needed for their hazard — from CO and H2S to methane or oxygen — while keeping installation fast and predictable. Designed to pair with the Honeywell 301-C controller, the unit receives 24V DC power and centralized supervision from the controller, reducing field wiring and simplifying system commissioning.

Built for integration, the E3Point E3SM supports Modbus and BACnet communications so it can easily join building management, security and process control networks. An internal relay provides immediate local alarm or equipment shutdown capability, improving response times and minimizing operational disruption. Constructed from durable PC housing and optimized for wall-mount applications, this gas detector base is ideal for plant safety, HVAC monitoring, parking garages, utilities and other critical infrastructure that demands reliable gas surveillance. Purchase the E3SM detector base to create a scalable, standards‑ready gas monitoring installation — or contact us to specify compatible sensors and controllers for your application.
