Multisensor detector with two integrated optical smoke sensors with different scattered light angles as well as additional heat detector sensor evaluation for detecting anything from smoldering fires to open fires with uniform response characteristics. Compares smoke sensor signals for smoke classification and reduction of false alarms from water vapor or dust, for example. Due to its excellent detection properties, the detector is also capable recognizing test fires TF1 and TF6 described in the standard. The O²T multisensor detector is also suitable for higher application temperatures of up to +65° C.
A remote indicator can also be connected.
Accessories:
767800 Assembly bracket
805590 Standard IQ8Quad detector base
805591 Detector base with IQ8Quad relay contact
Il rilevatore multicriterio O²T è adatto anche per temperature di applicazione più elevate, fino a +65°C. Inoltre, è possibile collegare un indicatore remoto.
