Removable screw terminal blocks
1-2 Input P1
Terminal for detecting the alarm contact (1 = contact, 2 = GND)
3-4 Relay R2
Auxiliary relay, range 30V-1Amp, normally open contact
C, A
Terminal for powering the system, irrelevant polarity
+ Vout
Terminal from which it is possible to draw power, POSITIVE
- GND
Terminal from which it is possible to draw power, NEGATIVE
LAN RJ45 port
The module requires a cable for connection to the LAN. If the cable also carries PoE power supply, it will not be
necessary to supply the module with other power sources. PoE power supply can coexist with any power supply
from an external power supply.
TAP Analog Port RJ45
All the signals connected to the traditional intercom are brought to this input to be processed by the internal
electronics and converted into VoIP-SIP protocols.
Devices powered via PoE (Power over Ethernet) may only be connected with cables coming from
inside the building, they are not allowed connections to LAN cables coming from outside the
building.
To the terminals 1 and 2 must only be connected to a relay or button contact that is free of any
voltage to avoid permanent damage to the device.
At the "+Vout" output there is a + 12Vdc voltage when the device is powered via PoE, otherwise, at
this output the voltage will be the same as at the terminals A-C. The use of "+Vout" is permitted as
long as it is not exceeded a maximum 200mA current consumption and the load has a protection on
the input current. Improper use of this output will permanently damage the unit.
IMPORTANT NOTE: the quality of the audio received and transmitted is strictly dependent on
the quality of the intercom system, the device does NOT correct any disturbances or low audio
quality of the existing intercom system but transfers the audio exactly as it receives it.
