Simplex 4098-5601

Simplex® photoelectric / photoelectric-heat detectors provide many of the proven analog sensing features for applications where detectors are connected to conventional 2-wire or 4-wire initiating device circuits (IDCs). Each detector has an onboard microprocessor that evaluates its photoelectric light scattering chamber activity and makes an intelligent decision based on light scattering history as to whether an alarm condition is present.
