The Honeywell E3Point is a versatile gas detector that utilizes flexible configuration options and multiple communications protocols to monitor and control toxic and combustible gases in commercial applications.

The E3Point uses self-testing diagnostics and an accurate, reliable electrochemical and catalytic bead sensor technology that reduces false alarms. The Honeywell E3Point Gas Monitor features an audible alarm greater than 85 dBA at 3m (10 ft) and has an accuracy of ± 3% of full-scale at 25°C. Gas concentration values, sensor data and other diagnostic information can be viewed on the Honeywell E3Point Gas Monitor main unit's LCD display. Interchangeable sensors are pre-calibrated at the factory and can be exchanged quickly and easily.

The Honeywell E3Point in available in both wall- and duct-mounting models. The Honeywell E3Point Gas Monitor can be configured as a standalone device with single or dual-gas (via remote sensor) monitoring or as a fully addressable, networked system that can be integrated with a building automation system such as Modbus or BACnet. Using the networked configuration, up to 96 addressable E3Point units can be linked, or daisy-chained, on a Honeywell Vulcain 301C Controller to various building systems such as a fire/security/HVAC network to increase the energy efficiency, performance and safety of new and retrofitted structures.
