Simplex 4098-5261Detector Base Simplex 4098-5261 Detector Base Simplex® photoelectric / photoelectric-heat detectors provide many of the proven analog sensing features. For detectors connected to conventional 2-wire or 4-wire initiating device circuits. Each detector has an onboard microprocessor. That evaluates photoelectric light scattering chamber activity. Makes an intelligent decision based on light scattering history as to whether an alarm condition is present. Simplex® photoelectric-heat detectors combine photoelectric smoke detection technology. And quick response thermistor-based heat detection technology. Into a sophisticated, intelligent detector that analyzes each of these activities and their combination to determine whether alarm conditions are present. This microprocessor-based analog detection maintains a response to conditions indicative. Maintaining the established high level of immunity to false alarms and nuisance alarms. An onboard microprocessor provides photoelectric detection with sensitivity drift compensation. Simplex® heat detectors use a fast response, thermistor-based design. To provide temperature sensing that quickly, accurately, and consistently. The fixed temperature sensing thermistor readily tracks the local ambient temperature. This eliminates the time required to melt a lead pellet or heat a bimetallic element. Occurs in mechanical heat detector designs. And provides the required heat detection for most applications. Bases are available for remote alarm LED indicator connections and auxiliary relay outputs.
