Hochiki Multi-Sensor with CO

Introducing the ACD-EN, the most sophisticated multi-sensor released to market to date. This revolutionary product offers a staggering 24 EN approved modes of operation, including combinations of smoke detection, fixed temperature heat detection, rate of rise heat detection, CO detection and COHb detection; making it ideal for a variety of applications.

The installer also has the ability to select a day mode and a night mode; increasing flexibility and ensuring reliability.

The ACD-EN is also enhanced for false alarm reduction. In modes featuring the Reduced False Alarm aspect (+RFA), the sensor will automatically adjust its sensitivity based on its surroundings, over time. The ACD-EN is installed with a default time delay.

If the environment is clean with no smoke detected for a period of time, this time delay is reduced. If the environment continues to be clean, the time delay is reduced again.

However, if transient smoke is detected, the time delay is increased. Any changes in CO and/or temperature will also automatically adjust the sensitivity levels up. We call this ground-breaking algorithm ‘Suitable Moving Average Time’ (SMART).

Compatible bases for the ACD-EN includes Hochiki Standard Base YBN-R/3, Hochiki’s Loop Powered Base Sounder (Ivory) YBO-BS, Hochiki Base Sounder Beacon Ivory Case Red LEDs (YBO-BSB2/RL) Hochiki Base Sounder Beacon Ivory Case White LEDs (YBO-BSB2/WL) and Hochiki Short Circuit Isolator Base YBN-R/3(SCI) (Ivory).
