Commercial Transmitters & Controllers

The Honeywell E3Point family of transmitters were designed to meet both stand alone applications as well as requirements to fully integrate with building control systems. Whether networked or as stand alone devices, the E3 point transmitters are designed for simplicity of installation and maintenance.

  • Flexible Operation: Stand alone, Stand alone with remote or networked versions
  • Cost Effective: Control fans, simplified installation
  • Advanced Sensor Technology: CO, O2, NO2, H2, H2S, methane & propane

Applications include vehicle garages, loading docks, battery rooms, vehicle and maintenance bays and commercial kitchens


The Standard for Mechanical Room Applications, the Honeywell 301EM is designed to meet the ASHRAE 15 B52 Mechanical Code.

The 301EM can be configured to offer automatic fan, horn and strobe activation in addition to manual fan activation. Latching relay for manual alarm recognition, silence key for manual horn deactivation, built-in 24 Vdc outputs for horn operation, and 2 breakglass switch accessories for manual alarm activation ensure optimal performance.

The AirAware family of transmitters are ISC/Oldhams solution for general purpose commercial and light industrial monitoring of hazardous gases

They can be configured to operate as a monitor with local LED display, a controller with onboard relay switching capability, a transmitter with 4-20mA or ModBus RTU outputs, or as a transmitter with on-board relays.

Sensors available for: CO, H2S, NO2, NO, SO2, NH3, Cl2, HCL and O2.
