Heiman HM-720-ES-WE Wirelessly Networked CO Detector – Group-Capable Carbon Monoxide Detector

The Heiman HM-720ESW is a smart carbon monoxide detector with an electrochemical sensor and 868 MHz wireless networking. In case of increased CO concentration, the detector immediately triggers an alarm – acoustically, optically, and synchronously with up to 40 networked devices.

In combination with a compatible smart gateway, the HM-720ESW can be integrated into an app. This allows you to conveniently monitor status, warnings, and temperature information remotely. Additional functions such as self-test, hush mode via app, and low battery warning make it the ideal solution for modern security concepts.

Typical Applications
– Networked CO protection in single and multi-family homes
