Simplex 4098-9714 Photoelectric Smoke DetectorSimplex 4098 9714 TrueAlarm photoelectric sensors use a stable, pulsed LED light source and a silicon photodiode receiver to deliver consistent and accurate low power smoke sensing There are three user selectable sensitivities for special applications for each individual sensor: 0. 2%, 0. 5%, and 1% for each foot. Standard sensitivity is 1. 25% to 3. 1% for each foot. The fire alarm control unit runs an algorithm that can vary the sensitivity for
