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 2.1.2 Base Comparisons on page 4).

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 when power is interrupted and the alarm condition

clears.

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 22.
