- Manufacturer: Hochiki
Introducing the ACD Multi-Sensor with CO. The most sophisticated multi-sensor Hochiki has brought to market to date.
This revolutionary product offers a staggering 24 EN54 approved modes of operation, including combinations of smoke detection, fixed temperature heat detection, rate of rise heat detection, CO detection and COHb toxicity recognition; making it ideal for a broad variety of applications.
The installer also has the ability to select a day mode and a night mode, increasing flexibility.
A Variety of Applications
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 toxic threat detection; making it ideal for a variety of applications.
Traditionally, CO detection is integrated into a multi-sensor to assist with the rapid detection of smouldering fires; however, the ACD-EN also features a highly sophisticated algorithm for adjusting its sensitivity according to its environment.
False Alarm Reduction
The ACD is enhanced for false alarm reduction.
In the modes featuring the Reduced False Alarm function (+RFA), the sensor will automatically adjust the sensitivity of the optical sensing element over time, learning from its surrounding environment from the moment of installation.
It does this through a highly sophisticated algorithm which continually monitors the analogue value reading from a series of multiple samples of the environment and calculating an average value.
This ‘moving average’ value is memorised by the sensor over time to determine the environment’s baseline reading.
We call this ground-breaking algorithm ‘Suitable Moving AveRage Time’, - SMART.
Flexible Settings
Each mode utilises different fire detection technologies either in combination or individually to generate a fire condition. This allows the installer the flexibility to “fine-tune” the ACD for any environment in which it is being fitted.
Furthermore, the ACD operates on Hochiki’s world renowned, robust and reliable, ESP open protocol, giving specifiers, installers and end users an open choice on system design, installation and maintenance; and therefore complete control over costs.
