Description
External siren designed for easy installation, sabotage prevention and weather
resistance.
The siren was designed to work both with E46ADCN or E49 power supply and with
buered E47ADCN power supply; the siren is tamper-proof against breaking/opening.
The siren is also protected by an anti-foaming device installed on the electronic board.
It is equipped with a patented anti-tampering anchorage system.

- Insert the plastic dowels in the holes.
- Break the pre-drilled hole (11) to insert the anti-tampering system screw .
- Partially tighten the two top screws and attach the siren to them (8).
- Tighten the two bottom screws (9). Fully tighten the four fastening screws and the
anti-tampering system screw.
- Tighten the tamper screws (10), without forcing it in case of installation on uneven
surfaces.
- Place the battery in the appropriate slot without connecting the Faston clamps. See
table below for battery type:
(**) If a second siren is installed to have additional signaling and it is not necessary to extend the
la system operating time in buer mode (mains power failure) a 2Ah battery can be installed.
- On the internal board, connect the power supply pair (BUS) to the appropriate clamp
(see next page).
- Position the cover and tighten the four xing screws (1) on the wall base.
Before working on the siren, put the system in maintenance mode.
The ashing of the siren LED, when exiting maintenance mode, indicates the BUS
polarity inversion.
If the red BUS led turns on, reverse the BUS polarity.
Not compatible with 4072A/4072L sirens.
In case of a second siren on the system, install another 4073.
Installation of the outdoor siren
- Remove the four screws (1) and take o the external cover (2).
- Use a drilling template (3) to position the hole (4) in correspondence of the wire
outlet pipe and trace the 4 holes for the fastening screws (5), the hole for the tamper
screw (6) and the hole for the anti-tampering anchorage (7) (Patent Pending).
NOTE: use a Ø 6mm bit for drilling the holes (*).

If there is a primary network power failure, operation is guaranteed
for the system by the battery installed inside the siren.
This solution allows using only one battery instead of the two used by traditional systems, thus
reducing maintenance and increasing system reliability by maintaining security.
Configure the siren as shown above.
If you want to guarantee a longer operating time for the system, a
second siren can be installed for the system, configuring it as shown
above.

Its presence is useful as a signaling device, but it is not required because the system buffer
battery will be connected to the power supply. The internal siren slot is used to accommodate
the siren self-supply battery and, therefore, a 2Ah battery will be sufficient.
Configure this siren as shown above.
If you want to install a second siren in order to have two signaling
points, you can install a second siren on the same system,
configuring it as shown above.
To change the conguration, put the control unit in maintenance mode and disconnect the batteries and the SCS bus
