Honeywell – 802473 OTG Multi-Sensor fire detector (CO) IQ8Quad

Multisensor fire detector with integrated smoke detector, heat detector and gas sensor (CO) with enhanced false alarm management, for preventive and early detection of deep-seated smouldering fires which give a lot of CO as well as flaming fires through combined evaluation of scattered light, temperature and gas. An alarm is actuated at carbon monoxide (CO) concentration levels that are life-threatening for humans. Less susceptible to false alarms caused by dust, as well earliest and reliable detection of fire development due to the additional detection of CO. Also a Technical Alarm (TAL) can be programmed with the flexible programmable CO threshold up to 150 ppm. The detector is provided with an integrated isolator. A remote indicator can be connected.

Detector-LED used as alarm indicator and as an indicator for detectors in service

Adaptation to changing operating conditions

Dedicated LED for indicating operation (green LED)

Disconnection of individual detectors, detector zones and detection areas

Disconnection of individual sensors or several sensors at once within a multisensor fire detector;

either manually or depending on programmed time of the day

Automatic adaptation to varying environmental conditions

Compensation of changing levels of air pressure, humidity, smoke concentration according to the

double chamber principle

Electronic compensation also called drift-compensation of long-term influences like aging or

pollution

Reliable detection

Constant alarm sensitivity of multisensor fire detector for all types of fire
