2.2.4 F220 Series Smoke Detector Heads

The F220 Series Smoke Detector Heads are UL Listed, open­area 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.

providing tamper protection. An EOL power supervision
module, such as a D275 or an F220-B6E Power Supervision
Base and an EOL resistor as specified by the control panel
manufacturer, supervises power.

3 Install the Bases

3.1 Mount the Bases

With the exception of the F220-B6E base, all four-wire bases
can be used in any combination within a loop. One F220-B6E
Power Supervision Base can be used as the last base on a loop
in four-wire systems to provide power supervision.

NOTE! Follow NFPA 72 guidelines for mounting locations.

i

For commercial and industrial installations, 30 ft (9 m)
spacing between smoke detectors is recommended.

1. Release the mounting skirt from the mounting base. Use a
screwdriver at the location of the snap locks (refer to
Figure 2.1, item 12, page 5) to release the mounting skirt.

2. Run all system wiring (refer to Section 3.2 Wire the Bases).

3. Mount the base using the two oblong mounting holes. Fits
4 in. square, octagon, AB, and single-gang back boxes.

3.2.2 EOL Resistors

Use the EOL resistors supplied or specified by the control panel
manufacturer. This applies to all loop terminations including the
D275 Module and the F220-B6E Power Supervision Base.

3.2.3 Loop Wiring Specifications

In a two-wire system, the maximum loop length depends on the
number of F220-B6 bases on the loop, the wire size, and the
control panel specifications. Refer to the control panel's
installation instructions for specific wiring information.
In a four-wire system, the maximum loop length and number of
bases that can be placed on a loop depend on the voltage drop
on the power circuit. Use standard voltage drop calculations to
ensure that the last detector on the loop meets the minimum
voltage requirement of at least 10 V.

4.3 Set CleanMe Feature

The Clean Me feature monitors the smoke chamber’s sensitivity
and sends a trouble signal to the control panel when the
sensitivity degrades to a preset level.

NOTE! When a CleanMe signal is sent to a control panel

i

that is not CleanMe compatible, the signal may be
misinterpreted as an alarm.

To activate the CleanMe feature:

1. Put the detector into sensitivity mode by placing a magnet
next to the T mark on the mounting skirt (refer to
Figure 4.2, Item 8 on page 19). Remove the magnet after
the first red LED flash and before the third red LED flash.

2. When the magnet is removed, the LED flashes green once
and shows the first of two sensitivity displays.

3. When the LED next flashes red, replace the magnet near
the T mark(refer to Figure 4.2, Item 8 on page 19).

4. Hold the magnet against the T mark on the mounting skirt
(refer to Figure 4.2, Item 8 on page 19) until the green LED
flashes twice and the red LED repeats the sensitivity
indication.

5. The detector exits sensitivity mode. If CleanMe has been
successfully enabled, the green LED flashes twice in rapid
succession every eight seconds indicating that CleanMe is
activated.

To disable CleanMe, repeat this process and verify the double
flash returns to a single flash.

4.4 Flash Rate and Trouble Indication

These detectors include the Chamber Check Automatic Trouble
Indicator that verifies the detector’s calibration is within the
factory listed range. NFPA guidelines for sensitivity testing can
be met by visually inspecting the detector and checking the
flash rate of the LED.

F220 Series Detectors with F220-B6/C/E/R Bases Test the Installation | en 23

NOTE! Perform the visual check before resetting power.
After a reset the trouble indicators clear for 70 seconds.

i

After 70 seconds, if the detector is in a trouble condition,
trouble indications begin again.

A unit with CleanMe activated double flashes (two flashes
within a half second of each other) every eight seconds. A
normally operating unit flashes once every eight seconds. If a
detector is in a trouble condition due to a dirty lens or a sensor
malfunction, it single or double flashes every four seconds. If
enabled, the CleanMe trouble signal is sent.

5 Test the Installation

5.1 Inspect the Installation

1. Check the wiring from the control panel to the last head on
each run for proper polarity and continuity.

2. Terminate each run with an EOL resistor as specified by
the control panel manufacturer.

3. Terminate four-wire runs with EOL power supervision
modules or F220-B6E bases.

4. Apply power to the system. Check for alarms and troubles.

5. Note which detectors alarmed (if any), shut down the
system, remove alarmed detectors from their bases, and
recheck the bases for proper wiring.

6. If the problem persists, determine if the problem is caused
by the detector or the base. Replace the affected detectors
or bases with known good units.

7. If a system alarm occurs with no detector alarms present,
remove all detectors and check the wiring at each base.

8. Check the wiring of each EOL resistor and EOL module.

9. When the system is alarm free, check each detector to
ensure that the green LED indicator flashes approximately

every eight seconds. This verifies the detector is receiving
power and operating properly.

NOTE! If a heat detector LED flashes at a rate of
4 flashes/sec, the detector is either cold (below +32°F

i

[0°C]), out of sensitivity range, or defective. If a smoke
detector flashes at a rate of 4 flashes/sec, it is either out
of sensitivity range or defective.

5.2 Test Each Detector

Test each detector to ensure it causes a control panel alarm.
Reset the control panel after each test.

5.2.1 Activate an Alarm at Each Detector

To cause heat detectors to alarm either:

– Activate the internal reed switch by placing a magnet

horizontally against the T mark on the mounting skirt (refer
to Figure 4.2, Item 8 on page 19) and holding it there for
three consecutive LED flashes, or

– Expose the thermistor (refer to Figure 2.2, Item 3 on

page 7)to a heat source such as a hair dryer or a shielded
heat lamp until the detector alarms and the alarm LED
lights .

To cause smoke detectors to alarm either:

– Activate the internal reed switch by placing a magnet

horizontally against the T mark on the mounting skirt (refer
to Figure 4.2, Item 8 on page 19) and holding it there for
three consecutive LED flashes, or

– Use a UL Listed aerosol smoke detector tester to simulate

an alarm. Follow the instructions provided with the aerosol
smoke detector tester.

5.2.2 Reset the Control Panel

When a detector alarms, the red LED indicator activates and
latches into the ON position. Clear the alarm by momentarily
removing power before proceeding to the next detector.

5.3 Test the Alarm Loop

Checkthe voltage across the EOL resistor of each alarm loop to
verify wiring losses do not exceed control panel manufacturer’s
specifications.

5.4 Test CO Sensors

Removing the detector head or resetting the detector’s power
places the detector in a special test mode for 15 minutes. If
over 35 ppm of CO is applied to the detector within this
15-minute period, the detector must alarm or it is defective.

WARN ING ! The F220-PTHC detects carbon monoxide

!

(CO) as a component of a fire. Do not use the F220-PTHC
as a stand-alone CO detector.

5.5 Perform NFPA 72 Required Testing

Refer to Section 1.2 Required Maintenance and Testing on
page 2.
