underneath the unit where indicated on the frame. The AC pilot lamp will
go out, the legend will flicker, but remain lit. Remove the magnet. The
AC pilot light will turn on, the legend will flicker but remain lit.
Automatic testing and diagnostics
A built in micro-controller will self-test the unit and identify display failures
of the unit on a monthly basis and identifies as well as displays failures of
the electrical components: battery, battery charger and LEDs.
Self-test
The self-test is performed every 30 days for 1 minute, every 6
months for 30 minutes, and annually for 90 minutes.
Diagnostic function
The diagnostic function uses a bi-color pilot LED indicator. Service is
required if the LED turns red indicating that an alarm condition is
detected (see Figure 6).
