detection chamber
The F220 Photoelectric Smoke Detectors are UL
Listed, open-area photoelectric smoke detectors. Use
them with commercial fire protective signaling
systems and household fire warning systems (see
NFPA 72, the National Fire Alarm Code). These smoke
detectors scatter light using a pulsed infrared source
operating with a gated, high-speed, photodiode
infrared sensor. The symmetry of the optical chamber
allows 360° uniform smoke entry, but minimizes
external light entry. The detectors use low current
electronic circuitry, so they can connect to 12 VDC
nominal or 24 VDC nominal power source circuits.
Functions
Compatible Bases
Configure the detectors into two-wire or four-wire
versions by selecting the appropriate mounting base.
These detectors are compatible with any of the
F220‑B6 bases:
• F220-B6 12/24 VDC Two‑wire Mounting Base
• F220-B6R Standard 12/24 VDC Four‑wire Mounting
Base
• F220-B6RS 24 VDC Four‑wire Mounting Base with
Sounder
• F220-B6C 12/24 VDC Four‑wire Mounting Base with
Auxiliary Relay
u Clean chamber without removal or disassembly
u CleanMe signaling capability
• F220-B6E 12/24 VDC Four‑wire Power Supervision
Mounting Base
• F220-B6PM 24 VDC Four‑wire Addressable Master
Base
• F220-B6PS 12/24 VDC Four‑wire Addressable Base
Monitoring the Detection Chamber
These detectors have several features that work
together to maximize the performance of the optical
chamber:
• Compensation: The detector monitors the chamber
for the effects of dust build-up within the chamber
and automatically compensates for these effects. If
the chamber becomes contaminated beyond its
ability to compensate, the green LED flashes every
4 sec to indicate trouble.
• Chamber Check Self-diagnostics: The detector
automatically indicates visually if the calibration is out
of the factory-listed range. This meets NFPA
guidelines for sensitivity testing, because you can
visually inspect the detector and check the flash rate
of the LED. If the calibration is out of range, the green
LED on the detector flashes once every 4 sec. This
indicates that the detector must be cleaned following
the instructions provided with the detector.

• CleanMe Mode: Indicates if the calibration is out of
the factory-listed range by sending a trouble signal to
the CleanMe-compatible control panel, if so
programmed.
• Chambermaid: The detector has a unique cleaning
mechanism. Use the valve on the back of the detector
to insert the nozzle of a can of clean, dry compressed
air. Clean the chamber with a short (1 to 2 sec) blast
of air.
Heat and Carbon Monoxide Enhancements
The detectors are available with an optional fixedtemperature heat sensor, a carbon monoxide (CO)
sensor, or a combination of heat and CO sensors.
These optional sensors enhance the operation of the
smoke detector by reducing false alarms.
• Carbon Monoxide: Without the presence of CO, a
normal byproduct of combustion, the detection
chamber is half as sensitive to smoke as a standard
commercial photoelectric smoke chamber. This
reduces false alarms. When the sensor detects CO,
the detection chamber's sensitivity to smoke
increases so it equals or exceeds that of a standard
commercial photoelectric smoke chamber.
Notice
The F220-PTHC detects carbon monoxide (CO) as
a component of a fire. It is not a CO detector and
cannot activate an alarm in the presence of CO
only.
• Heat: When the heat sensor detects a temperature
rise, the photoelectric chamber becomes more smoke
sensitive. The heat sensor initiates an alarm if the
ambient temperature exceeds +135°F (+57°C).
Dual-color LED
A dual-color LED indicator flashes green every 8 sec
when the detector has power and the smoke sampling
circuitry is working. If CleanMe is enabled, the green
LED double flashes (two flashes a half second apart)
every 8 sec to indicate normal operation. The LED
turns red if an alarm is sent. After the alarm condition
clears, reset the detector by interrupting its power. If
the chamber becomes contaminated beyond its ability
to compensate, the green LED flashes every 4 sec to
indicate trouble.
Test Functions
The F220 Photoelectric Smoke Detectors feature a
unique magnet operation and sensitivity test function.
Test the detector's operation by placing the magnet
next to the detector's LED for three consecutive
flashes. This causes the detector to send an alarm.
Placing a magnet next to the detector's LED for at
least one red flash but less than three flashes activates
the detector's sensitivity mode.
Tamper Detection
When detector heads are correctly installed in any of
the F220-B6 bases, the positive power line provides
tamper detection. The control panel initiates a trouble
signal if a detector is removed from its base. A
mechanical tamper lock comes with each base to
prevent unauthorized head removal.

Mounting the Bases
Notice
Consult NFPA‑72 for proper detector placement.
Depending on local regulations, the bases can be
surface mounted directly on four-inch square or
octagonal electrical boxes and single-gang switch
boxes.
Notice
The volume of any electrical box used should be
large enough to accommodate the number and
size of conductors as specified by the National
Electrical Code or any local authorities having
jurisdiction (AHJ).
