Description of Terminals
GND
This terminal protects EntryCom against static electricity damage.
SW1
Switch 1 designed primarily for electric doorlock control.
LIGHT
These two terminals are connected to the 12V power supply with
arbitrary polarity. The power supply can feed the electric lock too.
LINE
These two terminals are connected to the analogue telephone line with
any polarity.

VIDEO
+
Video signal output – used only if a camera unit is included. The
coaxial cable is connected with an internal conductor to +, with
shielding to -.
Description of Jumpers
Connector (8)
• Here connect the current call indicator (LED).
• Write-protection (if the jumper is mounted).
• do not connect
• Microphone sensitivity reduction (mount the jumper for noisy
environments).
Camera setting – connector (18): refer to the instructions enclosed to the camera unit.
Parallel Connection
Parallel connection of multiple telephone sets was commonly used in the era in
which telephone lines were rare, It carries unnecessary risks to connect the unit in this
way. It is in no case recommended to connect EntryCom in parallel to another
telephone or another EntryCom door communicator. It is neither admissible to use
equipment that switches one line between two or more sets (intelligent double branch,
etc.).
7.1. Common Instalation
Typical Electric Lock Connection
EntryCom contains a solid-state switch equipped with V-MOS transistors, which is
able to switch both ac and dc regardless of polarity. Make sure that the current and
voltage values do not exceed limits (refer to the Technical Data) and that the technical
parameters of the lock and power supply are compatible.
