Simplex 4098-9714 S/F 19/09 UV resistant enclosure providing protectionTrueAlarm photoelectric sensors use a stable, pulsed LED light source and a silicon photodiode receiver to deliver consistent and accurate low power smoke sensing. Three user selectable sensitivities for special applications are available for each individual sensor, 0. 2%, 0. 5%, and 1% per foot. Standard sensitivity is 1. 25% to 3. 1% per foot. The fire alarm control panel runs an algorithm that can vary the sensitivity for normal applications
