Required Maintenance and Testing
Keep the detector calibrated for proper operation. NFPA 72,
The National Fire Alarm Code, recommends performing
calibration tests at installation, then every other year.
Depending on local regulations, calibration testing might be
required more than once a year.
Perform functional testing yearly.
i
NOTE! Notify all concerned parties before any
maintenance or testing of the fire alarm system and upon
completion of these activities.
Test the calibration (to meet NFPA 72) using either the magnet
test or measuring the calibration with a calibrated product from
No Climb Products Ltd. Quickly determine the calibration by a
visual inspection of the detector’s LED (refer to Section 4.4
Flash Rate and Trouble Indication on page 24). These tests
confirm whether or not the detector is within its factory marked
calibration range.
At least once a year vacuum or wipe the external part of the
detector clean. Pay particular attention to the detector screens
in areas of heavy insect activity or dust. To clean the chamber,

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 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.

Electrical Supervision
When the F220-B6RS Bases are wired according to the
instructions in this document, the control panel initiates a
trouble signal when a detector is removed from its base,
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.

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.
i
NOTE! When a CleanMe signal is sent to a control panel
that is not CleanMe compatible, the signal may be
misinterprted 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 21). 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 21).
4.
Hold the magnet against the T mark on the mounting skirt
(refer to Figure 4.2, Item 8 on page 21) 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.

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.
NOTE! Perform the visual check before resetting power.
i
After a reset the trouble indicators clear for 70 seconds.
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. If the calibration is
out of range for more than 24 hours, the green LED on the
detector flashes approximately once every four seconds.

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.
5.
Apply power to the system. Check for alarms and troubles.
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.

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
i
4 flashes/sec, the detector is either cold (below +32°F
[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 and
holding it there for three consecutive LED flashes, or
–
Expose the thermistor 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 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.

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 any 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.
