Description
The Honeywell Analytics E3SA is a standalone, wall-mounted point gas detector engineered for reliable detection of toxic and combustible gases in commercial and industrial environments. Operating on 24 Vac or 24 Vdc power, this versatile unit integrates seamlessly into existing building automation and safety systems without the need for a separate controller.
Reliable Standalone Gas Detection
The E3SA is designed for single-point, standalone operation, making it an ideal solution for mechanical rooms, boiler rooms, parking garages, laboratories, and other facilities where gas leak detection is critical. The detector’s wall-mount form factor allows for straightforward installation in areas where toxic or combustible gas accumulation is a concern.
Key Features
- Operates on 24 Vac or 24 Vdc power supply for flexible installation
- Wall-mounted standalone design — no separate controller required
- Detects both toxic and combustible gases (sensor cartridge sold separately)
- Two (2) DPDT (Double Pole Double Throw) relay outputs for alarm and control integration
- 4-20 mA analog output for integration with building automation systems and data logging
- Built-in audible alarm for immediate on-site alert notification
- Modular sensor cartridge design allows field replacement and gas-type flexibility
Communication & Integration
The 4-20 mA analog output enables direct connection to PLCs, building management systems (BMS), and data acquisition equipment, providing continuous gas concentration monitoring. The two DPDT relay outputs can be configured to trigger ventilation fans, shut off gas valves, activate strobes, or interface with fire alarm panels — giving facility managers a complete safety response.
Audible Alarm
The integrated audible alarm provides an immediate local warning upon gas detection, helping to alert personnel in the vicinity before conditions become hazardous.
Sensor Cartridge (Sold Separately)
The E3SA uses a replaceable sensor cartridge, allowing the detector to be configured for a wide range of target gases. Sensor cartridges are available for various toxic gases (such as CO, H₂S, NH₃, and more) as well as combustible gases. This modular approach simplifies maintenance and reduces total cost of ownership over the product’s service life.
