Table 3: Press duration and resulting test
Duration Test Description
Short press Buzzer test only Generates the temporal-four
pattern twice.
Two seconds Buzzer test
SAFEtest Generates the temporal-four
pattern twice.
Allows functional CO gas
testing [1].
Five seconds Buzzer test
SAFEtest
Alarm relay test Generates the temporal-four
pattern twice.
Allows functional CO gas
testing [1].
Activates the alarm relay.
[1] Use the UL Certified “Solo C6” canned CO product from SDi
To test the buzzer:
1. Momentarily press the test/hush button.
The sounder generates four quick beeps, followed by five
seconds of silence, and then four quick beeps.
To perform the functional test with CO test spray:
1. Press and hold down the test/hush button until the red
LED illuminates (approximately 2 seconds).
2. Wait for the buzzer test to complete.
The red LED flashes every 4 seconds and the green LED
flashes every 16 seconds indicating that the device is in
CO test mode.
3. Direct a UL Approved CO testing agent spray to the
sensor port of the 260-CO.
The unit immediately goes into an alarm state upon
sensing the applied gas. The sounder and red LED
activates in a temporal-four pattern with a five second
pause in between. The alarm relay activates.
If the level of applied CO gas is still significant, the device
continues to alarm in this pattern.
4. Exit the SAFEtest mode by either:
• Pressing the test/hush button until the green LED
illuminates (approximately 2 seconds)
• Waiting five minutes, until the unit automatically exits
out of the SAFEtest mode
To perform the alarm relay test:
1. Press the test/hush button for approximately 5 seconds to
start a test cycle.
2. Wait for the buzzer test to complete.
3. Verify that the control panel reacts correctly to the alarm
relay activation.
4. The alarm relay test mode ends automatically after
10 seconds.
Maintenance
Note: The 260-CO is shipped from the factory as an
assembled unit; it contains no user-serviceable parts and
should not be disassembled.
Clean the outside of the detector each month with a clean cloth
(either dry or dampened with water) to keep openings free from
dust and dirt.
Do not paint the detector or expose it to cleaning solutions.
CO detector replacement
The 260-CO SafeAir Carbon Monoxide Detector has a long-life
carbon monoxide electrochemical sensor. Replace the detector
with a new 260-CO detector after 10 years from the date of
manufacture (found on the product label on the back of the
detector) or when the control panel goes into trouble and an
audible/visible annunciation occurs signaling “operational end
of life”.
