TEST
1. The carbon monoxide detector performs a self test when power to the LCFH is applied.
2. To test the CO detector, ensure that the power switch on the operator control box is in the ON
position.
3. Unscrew the small thumb screw (1) on the cover (2) protecting the CO detector (3). Open the cover.
4. Within a few seconds, the carbon monoxide detector will produce a series of four chirps, followed by
a delay of a few seconds, and then four more chirps. This indicates that the carbon monoxide
detector is operating properly. If the detector does not chirp as described, notify unit maintenance.
