Connecting the siren’s TAMPER to the Control Panel
At the “TAMPER” terminals, the Tamper contacts of the siren end up. When the siren is screwed
to the wall and its lid is closed, this output is NC and becomes NO when the lid is opened or
the siren detaches from the wall. These contacts can be connected to any perimeter or 24-hour
zone of the panel (such as NC or EOL zone, using EOL resistor), taking care to use the correct
polarity (COM & ZONE).
Caution!
If you use an EOL band, then, for greater security, place the EOL resistor in the siren,
at the TAMPER ZONE output and in series with the cable as shown in the wiring
diagram.
Power supply of the siren
The + 12V inputs are for powering the siren and charging the battery. They are connected to the
corresponding outputs of the Control panel, taking care of the correct polarity.
Caution!
For the siren to function properly, a battery must be used. In the case, however, that
you want the siren without battery to operate, you must connect the red battery cable
to + 12V. The siren can operate this way, provided the cable’s cross-section allows it
and the panel power supply is able to provide the required current.
Selecting the activation method of the siren
The TRIGGER (+ or -) inputs are used to activate the siren.
Activation can be done in two modes:
A. By positive voltage interruption
Connect the “+ TRIGGER” input of the siren to the corresponding output of the Control Panel
or a programmable output (PGM), that provides 12.0V at standby mode and cut or turns to 0 V
when an alarm is given.
B. By negative voltage interruption
Connect the “- TRIGGER” input of the siren to the corresponding output of the Control Panel
or a programmable output (PGM), that provides 0V at standby mode and become an Open
Collector or turns to 12.0 V when an alarm is given.
Note:
The siren follows the alarm duration of the Control panel. However, if the cables
connected to the panel are interrupted or shorted, the siren activates an alarm for a
maximum of 5 minutes.
