Installation Instructions

 If the Control Panel has not received the signal from the Carbon Monoxide Detector for a preset
period of time, the Control Panel will determine the Carbon Monoxide Detector has failed
supervision and is out-of-order.
 Carbon Monoxide Detection
 The alarm will be activated after CO concentration is detected according to time length in
following table:
CO concentration
level
Time taken before
alarming
30 ppm N/A
50 ppm 60~90 minutes
100 ppm 10~40 minutes
300 ppm Under 3 minutes
 Once the alarm is activated, the Carbon Monoxide Detector will transmit alarm signal and
activate its buzzer to raise alarm. The Red LED will begin to flash rapidly.
 After alarm activation, the Carbon Monoxide Detector will continue to sound alarm and resend
alarm signal every 2 minutes until the CO concentration drops below 30 ppm. When the
concentration drops below 30 ppm, the carbon Monoxide Detector will stop sounding alarm and
transmit a restore signal.
 Alarm Silence
 When the alarm is sounding, pressing the Test button will put the Carbon Monoxide Detector into
Alarm Silence mode for 10 minutes and the alarm will be stopped temporarily.
 After this 10-min period is over, the Carbon Monoxide Detector will check the Carbon Monoxide
concentration again. If the Carbon Monoxide concentration is still over the set threshold value,
the Carbon Monoxide Detector will sound the warning alarm again. If not, it will return to normal
operation mode and transmit restore signal.
 Self-diagnostics
The Carbon Monoxide Detector will perform self-diagnostics every 12 hours. The user can also press and
hold the test button for 10 seconds to perform self-diagnostics. If any fault is detected, the Carbon
Monoxide Detector will transmit signal to the Control Panel, and the Amber LED will flash every 5 seconds.
The following three conditions of Carbon Monoxide Sensor can be detected via self-diagnostics.
Condition Description Report to Control Panel
Good Sensor The CO Sensor functions normally. No
Short Sensor
The CO Sensor fails to function normally because t
he
positive and negative poles are connected together.
Yes
Open Sensor
The CO Sensor fails to function normally because
it has
come off or
either the positive pole or the negative pole is
broken.
Yes
 Learning
Step 1 Insert the 3 “AA” batteries into the battery compartment according to correct polarity shown
on the battery holder.
Step 2 When the batteries are inserted, the Carbon Monoxide Detector will sound 2 short beeps, and
the Red LED will flash once.
Step 3 Put the Control Panel into Learning mode, refer to Control Panel manual for detail.
Step 4 Press the Learn/Test Button on the Carbon Monoxide Detector to transmit signal to the
Control Panel for learn-in process. The Red LED will flash once with a beep.
Step 5 Refer to the operation manual to finish learning process.
