Before performing any actions on the siren, make sure that the
system is in maintenance mode.
The ashing of the siren ash LED when exiting maintenance
mode indicates an inversion of the BUS polarity.
If the red BUS LED comes on, invert the polarity of the BUS.
Not compatible with sirens 4072A/4072L.
If a second siren is installed as part of the system, the installation
of another 4073 is also required.

In case of primary network power supply interruption, system autonomy is ensured by
the battery installed inside the siren itself.
This solution means that only one battery can be used, instead of the two normally
used in traditional systems, therefore reducing maintenance and increase system
reliability by keeping safety levels unchanged.
Congure the siren as shown above.
If a higher degree of system autonomy is
desired, a second siren can be installed on
the system, congured as shown above.
System with
E47ADCN
power supply
It’s presence is useful for notication purposes, but is however not compulsory, as the
system back-up battery will be connected to the power supply unit.
The internal housing of the siren houses the siren self-powering battery itself. A 2 Ah
battery will therefore suce.
Congure this siren as shown above.
If a second siren is desired, in order to have
two notication points, a second siren can
be installed on the same system, congured
as shown above.
Foam
protection
The foam protection can be enabled using the SW2 conguration switch.
SW2 = ON (Foam protection enabled)
Bring the central unit into “Maintenance” and disconnect batteries and SCS bus to modify the conguration.
