Honeywell Analytics E3SM Gas Detector

The Honeywell Analytics E3SM Gas Detector is a high-performance, wall-mounted monitoring solution engineered for industrial gas detection in demanding environments. This standalone or network-enabled unit operates on 24Vac/24Vdc power and is designed to interface seamlessly with modern building automation systems. The E3SM features dual gas detection capabilities, allowing for an internal sensor and an additional remote sensor to monitor separate zones simultaneously. Its RS485 Modbus or BACnet MS/TP master communication ensures easy integration into established control architectures. Built with a rugged polycarbonate housing, the unit is resistant to corrosion and mechanical impact, making it suitable for mechanical rooms, laboratories, and parking structures. The device includes a DPDT relay for direct control of ventilation or safety equipment and an audible alarm for local notification. Please note that the Honeywell E3Point sensor cartridge is sold separately, allowing for field-replaceable sensing of carbon monoxide, nitrogen dioxide, or combustible gases. This model is functionally identical to the 1309A0047 and E3SB variants.

Key Benefits for Contractors

• Multi-Protocol Support: Simplifies setup with native BACnet MS/TP gas detector and Modbus RS-485 communication options selectable in the field.
• Reduced Installation Costs: The wall-mounted gas monitor design and 24V power requirement allow for rapid deployment without specialized high-voltage wiring.
• Daisy-Chain Connectivity: Facilitates network gas detection by allowing multiple units to be linked, reducing home-run wiring to the main controller.
• Integrated Diagnostics: The built-in LCD display provides real-time concentration data and system status, streamlining commissioning and troubleshooting.
• Flexible Output Control: Utilize the 4-20 mA current loop and DPDT relay to drive fans, louvers, or external horns based on user-defined setpoints.

Common Questions & Technical Support

How do I configure the Honeywell E3SM for BACnet or Modbus?
The communication protocol is selected via the internal menu or jumpers. As a smart gas detector, ensure the baud rate and MAC address/Device ID are set to match your network baseline for proper communication.

Does the E3SM include the sensing element?
No, this is the base monitor. The Honeywell gas sensor cartridge must be purchased separately based on the specific target gas (CO, NO2, H2, CH4, or O2) required for the application.

Can this unit monitor two different gases at once?
Yes, by connecting a remote E3Point sensor to the main E3SM unit, you can monitor two distinct locations or two different gas types from a single network node.
