Photoelectric & Heat Multi-Sensor

The multi-sensor 4098-9754EA combines the TrueAlarm photoelectric smoke sensor with a fast-acting and accurate TrueAlarm thermal sensor to provide both features in a single sensor/base assembly. Analog information from each sensor is digitally communicated to the control panel where it is analysed. Photoelectric sensor input is stored and tracked as an average value with an alarm or abnormal condition being determined by comparing the sensor’s present value against its average value. Thermal data is processed to look for absolute or rate-of-rise temperature as desired. Monitoring each photoelectric sensor’s average value provides a software filtering process that compensates for environmental factors (dust, dirt, etc.) and component aging. The result is a significant reduction in false or nuisance alarms caused by shifts in sensitivity.
