This Photo-Electric Smoke Detector is compatible with both the Simplex 4100ES and 4100U Fire Detection & Alarm Systems.
The TrueAlarm analog sensor provides an analog measurement digitally communicated to the host control panel using Simplex addressable communications. At the control panel, the data is analyzed and an average value is determined and stored. An alarm or other abnormal condition is determined by comparing the sensor's present value against its average value and time.
