3.11 OUTPUTS SIREN CONNECTION EXAMPLES
3.11.1 Connecting a self-powered siren with 3 or 2 wires
3.11.2 Connecting a non-self-powered indoor siren
The control panel is equipped with a relay capable of supporting
3A at 24V , with potential-free exchange, which is assigned by
default to the control of an alarm sounder. This relay can be
used to control a self-powered siren and a standard siren. The
exchange is accessible via the terminals COM (common), NC
(exchange closed to common in standby) and NO (exchange
open in standby) of terminal block M3-M4.
A positive dedicated to charging the battery of a self-powered
unit is available on terminal V+SIR of terminal block M4. This
positive is limited by a 0.75 A resettable fuse.
With 3-wire connection, the control panel passes only one
block positive through the relay associated to the alarm; the
siren power supply is connected separately to two terminals on
the control panel (V+SIR and V-). In an alarm state, the block
positive is removed and the siren sounds, being able to use its
backup battery and the system battery.
With 2-wire connection, the control panel passes a block
positive and recharges through the relay associated to the
alarm. The siren negative is connected to the control panel V-.
In an alarm state, this positive is removed and the siren sounds
under its own power.

It is sometimes necessary to connect an additional, non-self-
powered, indoor siren as backup for the outdoor siren. Using
two-wire connection for the outdoor self-powered siren
simplifies the wiring, as shown in the circuit diagram below.

3.10 WIRELESS SENSORS AND ACCESSORIES
For further information on the correct positioning and mounting
of wireless sensors and sirens, refer to the respective instruction
sheets enclosed with the devices in question:
• Bidirectional PET Immunity infrared sensor, via radio
(Art. RFPIRP)
• Magnetic contact sensor with radio transceiver (Art.
RFMAGW/ RFMAGB)
• 4-key radio control (Art. RFREMOTE4)
• Self-powered indoor siren (Art. RFINTSIR)
• Self-powered outdoor siren (Art. RFEXTSIR)
• Wireless smoke and heat detector (Art. RFSMOKE)
• Radio anti-panic button (Art. RFPANIC)
• Infrared volumetric radio sensor with camera (Art.
RFPIRCAM)
It is recommended to use a shielded cable for the
connections,with one end of the shield connected to V-
and the other left free.
The 2-wire connection is recommended if using sirens that
require a current higher than 0.75 A in alarm mode
