The models CD8110 and CD8180 are a sealed lithium battery powered wall mounted
detector. Two 10-year lithium battery cells are permanently sealed with soldered
connections, and cannot be removed. No battery replacement is required under normal
conditions.
8. FUNCTIONS AND OPERATION
OPERATION:
The CO detector is operational once the activation switch is slid to ON
position, and a one minute warm-up is complete. The
POWER
green LED will flash
once every 60 seconds, and model CD8180 LCD continuously display
.
LOW BATTERY CONDITION:
When the battery voltage drops below an acceptable
level, the detector will chirp once per minute and the
POWER
green LED will blink 5
seconds every minute. The model CD8180 LCD will also display
symbol. The
detector will continue to sample for carbon monoxide, and model CD8180 automatically
display CO levels detected of 30 ppm or more, until battery power drops below
minimum voltage requirement. See Section 13 for information regarding service.
SERVICE CONDITION:
An internal microcontroller continuously monitors the sensor
function and other critical components. If an internal failure of any of these components
