1.0 General Information
1.1 F220-B6 Series Bases
Use with the F220 Series Heat and Photoelectric
Smoke Detectors. Install them in accordance with
NFPA 72, The National Fire Alarm Code.
For proper system installation, read and
understand NFPA-72, The National Fire
Alarm Code before installation.
This document covers mounting, wiring, power
requirements, testing, and maintenance for the bases
and detectors:
•
For two-wire compatibility information see the
Technical Service Note (P/N: 4998148185).
•
For installation guidelines see the Technical Service
Note (P/N: 26715).

Use with F220 Series bases to provide general property
protection.
The F220-135, F220-135F and F220-
190F are not life safety devices.

Photoelectronic Smoke Detectors
The F220P Series Detectors 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.
For commercial and industrial installations, 30 ft
(9.14 m) spacing between detectors is recommended.
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 finds an alarm condition, 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 readjusts 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 transmits a
CleanMe signal to the compatible control panel to
indicate a dirty smoke detector.
See
Section 1.5 CleanMe toggle to enable CleanMe.
1.5 CleanMe toggle
To activate the CleanMe feature:
1.
Place a magnet next to the “T” marked on the
detector base for more than one red LED flash but
less than three red LED flashes. The LED flashes
green one time and proceeds into the first of two
sensitivity reading displays.
