Signature device maintenance tips
Detectors
When removing one detector at a time, wait 1-minute after replacing the first
detector before removing the next detector. This gives the system time to
recognize and remap the first detector before generating a trouble condition
caused by removing the second detector.
CO maintenance alert
In addition to displaying a maintenance alert when the photo element dirtiness is
at or above 80%, the loop controller displays a maintenance alert when the CO
sensor module is at or below 6 months until end-of-life. If both elements are at or
above these thresholds, there is only one maintenance alert.
Once the dirtiness threshold is at 100%, a dirty detector trouble displays for the
photo element. Once there are zero months until end-of-life, the panel displays
the CO end-of-life trouble message.
CO maintenance report
The CO sensor module has a life span of 6 years. After 6 years, the detector
sends out an end-of-life trouble message. When the message is transmitted,
replace the CO sensor module.
To determine the months until end-of-life, run a maintenance report from the LCD
screen. See “Device maintenance reports” on page 52.
