Connections
4.1 Power supply
When the Security Player is connected to the 230V ac power supply, via the appropriate
supply cable provided, the red LED POWER comes on.
4.2 Inputs
Security Player has eight logical optoisolated inputs for controlling the reproduction of the
messages.
The pins are:
IN 1
1-
IN 2
2-
IN 3
3-
IN 4
4-
IN 5
5-
IN 6
6-
IN 7
7-
IN 8
8-
COM IN
9-
In order to activate the reproduction of a file, apply a voltage between +5 e +12Vdc to
COM IN (common inputs) pin and the required input (or the required inputs if working in
binary logic). The positive can be connected either on the COM IN or on the input pin.
The input is activated by connecting it to GND (pin 11) on the Security Player.
N.B. the external power supply source must be able to guarantee a current of at least
10mA for each input.
If an external power source is unavailable, it is possible to connect the COM IN to the
+12V (pin 10) terminal on the Security Player. N.B. Galvanic isolation is not guaranteed in
this case.
4.3 Relay output
The relay output on the Security Player is normally an open contact.
Activation of this output occurs in the moment in which the reproduction of an audio file
begins and is maintained for the whole duration of the file.
N.B. The relay is not activated during the reproduction of the file Analyzer.mp3.
4.4 Audio output
The audio output on the Security Player is available on an extractable terminal in balanced
mode (0dBu).
