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 Normal Applications Between 1.25% And 3.1% For Each Foot.
