3.1 INITIAL DIAGNOSTICS
The HPA800 siren is equipped with innovative diagnostic functions to allow the installer to check correct
operation and connection of the siren to the control panel before closing the siren cover and completing
installation.
When the siren is powered, by connecting the battery or the voltage from the control panel, a sequence of low
volume tones is emitted and all LED simultaneously flash in order to check the correct operation of horn and
LEDs.
Then, the siren emits a LED flashing and tone cycles to indicate the condition of the inputs, as shown in the
following table:
