The F220 Series Smoke Detector Heads are UL Listed, open- area photoelectric smoke detectors that work with commercial fire protective signaling systems and household fire warning systems. Select the appropriate mounting base to configure the detectors for
Section 2.1
To verify power to the detector and a functioning smoke sampling circuitry, a dual color LED indicator flashes green every eight seconds when operating normally. It flashes once every four seconds when a trouble condition exists. If the detector determines an alarm condition exists, the LED changes from flashing green to steady red. The detector returns to normal after the alarm condition is cleared and power is interrupted.
Throughout its normal life cycle, the smoke detector monitors and periodically adjusts itself to keep the sensitivity at its factory calibrated level. When excessively dirty, the detector’s LED flash rate changes from an eight second flash rate to a four second rate. If CleanMe is selected, the detector sends a CleanMe signal to the compatible control panel to indicate a dirty smoke detector.
Refer to Section 4.3 Set CleanMe Feature on page 24.
