OTG fire detector

OTG multisensor fire detector IQ8Quad.
It incorporates 3 technologies: thermovelocimetric, smoke optic with Tyndall effect chamber and a CO gas detector.
Approval EN54, VdS G205072

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.

Continuous monitoring of the status of the optical chamber and sensor electronics, including continuous monitoring of CPU functionality. Automatic drift compensation in case of variations due to critical environmental conditions (e.g. dust and/or humidity). Presence of experimental false alarm algorithms which, when properly compared with the environmental information collected, allow the false alarms to be eliminated and not evaluated as fire alarms. By means of further specific algorithms, the detector is able to identify any electromagnetic disturbances generated by equipment such as inverters, conveyor belts, radio/wireless equipment and audio speakers. Integrated short-circuit isolator. Two-colour LED for evaluation of operating and alarm status. Thermal sensor operating class: A2. Degree of protection: IP40 extendable to IP 43. Ring identification colour: Gold.
