Connecting outputs
Alarm devices (sirens and flashing lights), signalling devices (LEDs or buzzers), or even other devices that operate
automatically upon the activation of a detector can be connected to system outputs.
IMPORTANT!
Never exceed the current or voltage supported by the outputs (see the technical characteristics of
individual products).
IMPORTANT!
Connect only operating circuits with SELV voltage.
Output specialisation (intrusion, tampering, panic, technological, etc.) is specified successively via programming. At least
one output must be programmed for the signalling of alarms (siren).
IMPORTANT!
In order to maintain conformity with standard EN50131-3, the CUSTOMIZATION functions of the
OUTPUTS present in the control panel must not be modified.
IMPORTANT!
In order to guarantee conformity with standard EN50131-3, the TAMPER output (OUTPUT No. 2)
must command only sirens for indoors, in that when the system is disarmed it does not allow an external alarm to
be activated in case of tampering.
Two types of output are available: a relay and an electrical one.
5.12.6.1 Relay outputs
Relay outputs have a switch contact between
C
terminal (shared contact) and
NC
terminals (contact normally closed)
and
NO
(contact normally open).
5.12.6.2 Electrical outputs
Electrical outputs can be:
“positive reference”, pro12 V
“negative reference”, providing 0 V
In both cases, the electrical output is “high impedance” (
∞
ohm) when it is open (with no electric potential).
Electric outputs can be used to control power relays or signalling LEDs.
In the control panels, electrical outputs can be individually configured as "positive reference" or "negative reference", as
detailed in
The expansion has only 2 electrical outputs av
ailable, both only “negative reference”: U2 and U3.
