Honeywell E3SA Gas Detector

The Honeywell E3SA Gas Detector is a high-performance, standalone solution designed for the detection of toxic and combustible gases in commercial and industrial environments. Engineered for wall mount gas detection applications, the E3Point E3SA operates on 24Vac or 24Vdc power and features dual DPDT relays for flexible control of ventilation fans, dampers, or remote alarms. This unit serves as the direct replacement for Honeywell 1309A0042, 1309A0044, and E3SAR models, simplifying maintenance for legacy systems. With integrated 4-20mA communication and a built-in audible alarm, it provides reliable toxic gas monitoring and combustible gas safety. Its modular design utilizes plug-and-play sensor cartridges (sold separately), allowing for quick field replacement and reduced downtime. Whether used in parking garages, mechanical rooms, or warehouses, the E3SA ensures precision monitoring and seamless integration with existing building automation systems, making it a staple for contractors prioritizing rigorous ventilation control and safety compliance.

• Multi-Voltage Compatibility: Operates on 24Vac/Vdc, allowing for direct integration with standard HVAC control circuits.
• Dual DPDT Relays: Provides two independent Form C contacts for triggering multi-stage ventilation or local alarm indicators.
• Modular Sensor Design: Supports various smart sensor cartridges for detecting CO, NO2, H2, and other gases without needing to replace the base unit.
• Direct Retrofit: Engineered to replace discontinued 1309 series detectors, reducing labor costs during system upgrades.
• Audible and Visual Indication: Features an onboard 85dB internal buzzer and clear LED indicators for immediate status awareness.

Is the sensor included with the E3SA base unit?
No, the Honeywell E3SA base unit does not include a sensor. You must specify and purchase the correct sensor cartridge (e.g., CO or NO2) separately based on your specific application requirements.

Can this unit be integrated into a larger BMS network?
While the E3SA is a standalone gas detector with 4-20mA output and relays, it can be integrated into a Building Management System (BMS) via the analog signal for real-time monitoring and data logging.

What is the proper mounting height for this detector?
Mounting height depends on the target gas density. For CO detection, mount at 5 feet (breathing zone); for NO2, mount approximately 1 foot from the ceiling; for heavier-than-air gases like propane, mount 1 foot from the floor.
