ACD-EN Addressable Multi‑Sensor: CO, Smoke & Heat Functions
This article explains which gas the ACD-EN addressable multi‑sensor detects and the core sensor functionalities described.
Summary
The ACD-EN is an addressable multi‑sensor that includes CO detection alongside multi‑sensor detection capabilities (smoke and heat). It can operate in different ways.
What gas the ACD-EN detects
- Carbon monoxide (CO)
Core sensor functionalities
- Multi‑sensor functionality: the device incorporates smoke and heat sensing elements as part of a combined multi‑sensor.
- CO detection: the CO sensing function is provided as a separate detection element within the same multi‑sensor device.
- Configurable operation: the ACD-EN can be set to operate in different ways (different modes of operation are available).
How the functions relate (operational note)
- The unit combines multi‑sensor detection (smoke and heat) with an integrated CO detector in one device.
- The CO detection and the multi‑sensor elements are distinct functions within the ACDEN; the device supports multiple ways of working to meet different application needs.
Conclusion
The ACD-EN provides integrated carbon monoxide detection together with combined smoke and heat sensing in a single addressable multi‑sensor. The device supports configurable modes of operation so the CO and multi‑sensor functions can be applied according to system requirements.
