The Simplex 4098-9701 is a reconditioned TrueAlarm analog photoelectric smoke sensor for Simplex addressable fire alarm systems. Reconditioned by qualified technicians to meet original manufacturer specifications, the 4098-9701 provides a cost-effective alternative to new sensors without sacrificing performance or reliability — making it an excellent choice for budget-conscious facilities managing large Simplex installations.
Like new TrueAlarm sensors, the 4098-9701 reports continuous analog chamber values to the Simplex FACP rather than a simple alarm/normal binary signal. This enables the panel to apply drift compensation, pre-alarm thresholds, and intelligent alarm processing that dramatically reduces false alarms while maintaining early warning capability.
