Simplex 4098-9714 Analog, Photoelectric, Sensor, Smoke Detector

Simplex 4098-9714 True Alarm Photoelectric Sensor / DetectorThe Simplex 4098-9714 True Alarm photoelectric sensors use a stable, pulsed infrared LED light source and a silicon photodiode receiver to provide consistent and accurate low power smoke sensing.  Seven levels of sensitivity are available for each individual sensor, ranging from 0.2% to 3.7% per foot of smoke obscuration.  Sensitivity is selected and monitored at the fire alarm control panel. The sensor head design provides 360° smoke entry for optimum response to smoke from any direction.  A built-in screen keeps insects from entering the smoke chamber.  Due to its photoelectric operation, air velocity is not normally a factor, except for impact on area smoke flow. This photoelectric detector can be used with the 4010 and 4100U series control panels from Simplex. It also is compatible with the 4008, 4020, 4210, and 4100 series, as well as with 2120 True Alarm CDT's. This high-quality sensor will ensure your system is always in proper working order, so place your order today and we'll ship it to you immediately. True Alarm 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 normal applications between 1.25% and 3.1% for each foot. Note: Fixed sensitivity settings higher than 1.0% for each foot are not UL268 7th Edition compliant. The sensor head design provides 360° smoke entry for optimum response to smoke from any direction. Due to its photoelectric operation, air velocity is not normally a factor, except for impact on area smoke flow.
