Simplex 4098-9789 SSD Sensor Base

Simplex 4098-9789 SSD Sensor Base with wired connections for 2098-9808 Remote LED alarm indicator or 4098-9822 relay (relay is unsupervised together with requires separate 24 VDC).

In general, Simplex 4098-9789 provides an analog measurement digitally communicated to the host control panel using Simplex addressable communications. At the control panel, the data is analyze and an average value is determine and stored. An alarm or other abnormal condition is determine by comparing the sensor’s present value against its average value and time.

Monitoring each sensor’s average value provides a continuously shifting reference point. This software filtering process compensates for environmental factors (dust, dirt, etc.) and component aging, providing an accurate reference for evaluating new activity. With this filtering, there is a significant reduction in the probability of false or nuisance alarms caused by shifts in sensitivity, either up or down.
