HoneywellHoneywell E3Point Gas Monitor

Honeywell E3Point Gas Monitor

E3Point is a toxic/combustible gas monitor that makes a commercial operation run more intelligently to protect people and property.

E3Point is capable of detecting the widest range of toxic and combustible gases found in commercial building spaces, including CO, NO2, O2, H2, H2S, CH4 and C3H8. It can be used as a standalone unit with single or dual-gas detection (i.e. using a remote sensor) or deployed as a networkable device (interoperable with BACnet, Modbus or other Building Automation System); E3Point also functions with existing controller-based gas monitoring systems and wired gas monitoring system components.

E3Point uses Demand Control Ventilation—through relays, Building Automation System (BAS) or controller—to increase energy savings, extend fan life and align with green building best practices. In its network configuration, E3Point also optimises HVAC, fire/smoke, surveillance and other building systems performance.

  • Complete toxic and combustible gas detection system with onboard sounder
  • Available in a single point or dual gas options
  • Analog 4-20 mA or Digital outputs (Bacnet, Modbus, and LonWorks)

Flexible Operation

  • Comes in standalone, standalone with remote (dual gas mode) or network versions
  • Connects to analogue or digital systems
  • Works with virtually any BAS including BACnet and Modbus
  • Connects to a wired or wireless system (via a 301CW wireless controller)
  • Wall or duct mount
  • Factory-calibrated cartridges

Cost Effective

  • Saves energy through Demand Control Ventilation (DCV)
  • Simplifies installation/maintenance through a plug-n-play sensor
  • Remote sensor option provides dual gas monitoring (standalone version only)
  • Optimizes BAS, fire, ventilation and other security systems


Versatile Communications

  • Works through BAS to improve fault diagnostics and collect data on gas concentration levels, sensor condition, etc.
  • Couple with 301C to log data and daisy-chain up to 96 E3Point units


Advanced Sensing Technology

  • Detects CO, NO2, O2, H2, H2S, CH4, C3H8
  • Advanced electrochemical (for toxic gases)and catalytic bead (for combustible gases)  sensor performance
  • Uses patented Reflex® and smart cartridge technologies


  • Factory-calibrated replacement cartridges
  • Power transformer
  • Steel-wire detector guards
  • Tamper-proof screws (main unit only)
  • Strobes and horns
  • Wall or duct mount
