HPA800
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:

Balance
alarm input (ALL)
and system status (TC)
the alarm inputs (ALL)
and the system status
(TC) were balanced by
means of 10 Kohm
resistor connected in
series
the alarm inputs (ALL)
and the system status
(TC)
are not balanced

Siren condition
3-flash cycles
-
at least either the alarm input, the cover
microswitch or the anti-foam protection* is open
2-flash cycles
-
cover microswitch and anti-foam protection* are at
rest but the alarm input is open
3-flash cycles
cycles of 3 tones
the alarm input is at rest but at least either the cover
microswitch or the anti-foam protection is open
