O²T multisensor detector,
w. isolator, Series IQ8Quad

Multisensor detector with two built-in 
optical smoke sensors with different 
scattered light angles as well as 
additional heat detector sensor 
evaluation for detecting everything from
 smouldering fires to open fires with 
consistent response behaviour. Smoke 
sensor signal identification to ensure 
smoke classification and reduction of 
deceptive alarms caused, for instance, 
by water vapour or dust.
