However,the panel,selectable as the individual application requires. standard seven levels of TrueAlarm sensor sensitivity are Sensor Status LED.Each sensor housing's red status available for each individual sensor,ranging from 0.2%to LED(located on the electrical interface board)pulses to 3.7%per foot of smoke obscuration.
