Honeywell Analytics E3DA Gas Detector

The Honeywell Analytics E3DA Gas Detector is a specialized duct-mounted gas monitoring system designed to deliver reliable protection against toxic and combustible hazards in HVAC ductwork and confined air streams. Operating on a versatile 24Vac/Vdc power supply, this standalone E3Point interface is the specified direct replacement for the legacy 1309A0049 model. It features a robust 4-20mA analog output for seamless integration into Building Automation Systems (BAS) and existing monitoring controllers, ensuring continuous data transmission of gas concentrations. To facilitate local alarm management and ventilation control, the unit is equipped with two DPDT relays and an integrated audible alarm. Please note that the sensor cartridge is sold separately, allowing technicians to customize the device for specific gases such as Carbon Monoxide (CO), Nitrogen Dioxide (NO2), or Combustible (LEL) gases. The enclosure is engineered to handle airflows between 500 and 4000 ft./min, making it an essential component for Demand Control Ventilation (DCV) and energy efficiency strategies in commercial mechanical rooms.

• Direct Legacy Replacement: Engineered as the exact substitute for part number 1309A0049 to minimize duct modification during upgrades.
• Versatile Alarm Control: Dual DPDT relays allow for simultaneous activation of exhaust fans and remote strobes or sirens.
• Simplified Integration: Standard 4-20mA communication ensures compatibility with most industrial and commercial HVAC controllers.
• Optimized for Airflow: Specifically designed for duct applications where ambient wall-mount sensors cannot provide an accurate sample of the air stream.
• Rugged Performance: Built with a corrosion-resistant housing to withstand the temperature and pressure fluctuations typical of HVAC ducting.

Which sensors are compatible with the E3DA base unit?
The E3DA supports the full range of Honeywell E3Point plug-and-play sensor cartridges, including CO, NO2, O2, H2, and CH4. Cartridges must be ordered according to the specific gas hazard identified for your facility.

Does this unit support dual gas monitoring?
Yes, while it functions as a standalone protector, the E3Point Analog platform can accept one additional remote sensor, allowing a single E3DA to monitor two separate locations or two different gases simultaneously.

What is the proper mounting orientation for duct installation?
The sampling tube must be oriented so the intake holes face directly into the airflow. It is critical to verify the air velocity is within the rated 500–4000 ft./min range for accurate gas sampling.
