con- temporary design and enhanced optical sensing chamber is engi- neered to sense smoke produced by a wide range of combustion sources in accordance with more stringent code standards

and lights an individual zone lamp in zoned systems

The module increases the number of programmable relay outputs from 19 to 59 and expands system users to 100

These units sense smoke in challenging conditions

Simplex GSA4098-9714 Smoke Detector SF 28/11 and when two consecutive signalsTrueAlarm analog sensors provide an analog measurement digitally communicated to the host control panel using Simplex addressable communications. The control unit analyses the data, determines an average value and stores it. Comparing the sensor's present value against its average value and time, determines an alarm or other abnormal condition. Monitoring each sensor's average value provides a continuously shifting reference point. A software
