DURING USE
The yellow LED on the Digital Display starts to flash and the BAC beeps when the ADSU
is in sensing mode. When there is a lack of motion for 30 seconds the ADSU will go into
pre-alarm. This is indicated by an escalating audible signal from the BAC and alternate
flashing of the yellow and red LEDs on the Digital Display and the main LED of the BAC.
After the pre-alarm, the unit enters alarm mode.
When activated, the unit may be put into alarm mode at any time by pressing the
panic button.
In alarm mode the BAC emits a loud audible signal, the yellow and red LED on the
Digital Display will alternate, the backlight of the display flashes yellow and red and
the main LED on the BAC flashes red.
INTERNAL EVACUATION SIGNAL
This function is configuration dependent and only available on the version with the
tally key. To activate, press and hold the backlight button and then press the panic
button.
The signal is the same as the alarm mode described above, but with a different
intermittent warning sound.
