Description
The Honeywell Analytics E3SM is a professional-grade, wall-mounted point gas detector engineered for reliable detection of toxic and combustible gases in commercial and industrial HVAC environments. Operating on 24Vac or 24Vdc power, it integrates seamlessly into modern building automation systems via RS485 BACnet MS/TP or Modbus communication protocols, making it an ideal choice for networked gas detection applications.
Key Features
- Operates on 24Vac or 24Vdc power supply for flexible installation
- Detects both toxic and combustible gases for broad application coverage
- Supports RS485 BACnet MS/TP or Modbus master communication for seamless BAS integration
- Includes 1 DPDT (Double Pole Double Throw) relay output for alarm or control actions
- Built-in audible alarm for immediate on-site alert notification
- Wall-mounted design for convenient, space-saving installation
- Sensor cartridge sold separately — select the appropriate cartridge for your target gas
Communication & Integration
The E3SM supports RS485 Modbus RTU and BACnet MS/TP master protocols, enabling direct integration with building automation systems (BAS) and energy management platforms. This network-ready design simplifies multi-point gas detection deployments and centralizes monitoring across large facilities.
Relay & Alarm Output
Equipped with one DPDT relay, the E3SM can trigger downstream devices such as ventilation fans, damper actuators, or control panels upon gas detection. The integrated audible alarm provides an immediate local warning to building occupants and maintenance personnel.
Sensor Cartridge Flexibility
The E3SM platform uses interchangeable sensor cartridges (sold separately), allowing the detector to be configured for a wide range of toxic or combustible gas types. This modular approach simplifies maintenance and future upgrades without replacing the entire unit.
