2.2.4 F220 Series Smoke Detector Heads
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 two-wire or four-wire versions (refer to
Section 2.1 F220-B6RS Detector Bases on page 3).
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.
