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.
