To make your carbon monoxide alarm tamper resistant, a locking pin has been
provided in the bag with the screws and anchors. Using this pin will deter children and others
from removing the alarm from the mounting plate. To use the pin insert it into the hole in the
side of the alarm after the alarm has been installed on the mounting plate (see figure 6). To
remove the alarm, use long nose pliers pull the pin out of the hole; it is now possible to
remove the alarm from the mounting plate.
Test alarm immediately following installation

pushing the test button until a short beep is heard (approximately three seconds). Release the button. The alarm will then test itself
