Aritech DT992CO 990 Series Discovery COHeat Multi-Sensor
Aritech DT992CO 990 Series Discovery COHeat Multi-SensorThe DT992CO combination carbon monoxide and heat detector is an elegant slim-line addressable detector. It detects the presence of carbon monoxide or heat or a combination of both depending on the operating mode selected.Operating ModesThe DP992CO supports 5 operating modes for various applicationsVery high sensitivity CO moderate heat - For a high overall sensitivity to both smouldering and flaming firesCO Detection onlyModerate sensitivity CO moderate heat - For general fire applicationsLow sensitivity CO moderate heat - For areas where a certain amount of CO is normalTemperature only A1ROperating PrinciplesThe signals from the CO cell and temperature sensor are independent of each other. They individually represent the amount of CO or heat in the vicinity of the detector. When the DT992CO is used in heat only mode it performs like a standard A1R grade 1 rate-of-rise thermal detector whilst in CO only more the detector acts as a pure CO fire detector.Key Features5 Approved response modes for ease of optimisation to different environmentsRejection of transient signalsDrift compensation to ensure constant sensitivity360 Alarm visibilityFlashing LED optionFast alarm reportingEN54 approved and CPR certifiedApollo equivalent 58000-305
