Before performing any actions on the siren, make sure that the
system is in maintenance mode.
The flashing of the siren flash 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.
LED and configuration switch:
Bring the central unit into "Maintenance" and disconnect batteries and SCS bus to modify the configuration.
System with
E46ADCN or
E49 power
In case of primary network power supply interruption, system autonomy is ensured by
supply
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.
Configure the siren as shown above.
System with
E47ADCN
power supply
It's presence is useful for notification 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 suffice.
Configure this siren as shown above.
