2 Terminal wiring and putting into operation
2.1 Input wiring
For the inputs, the normally closed or normally open dry contact should be connected between
the given input (
IN1
…
IN4
) and the negative of the power input (
V-
) or the
COM
terminal.
If a normally open dry contact is used to activate the input, choose the
NO
(normally open) option
in
the given input’s settings. In this case, the input will become activated when the open contact
between the given input (
IN1
…
IN4
) and the
V-
terminal (or the
COM
terminal) becomes closed.
If a normally closed dry contact is used to activate the input, choose the
NC
(normally closed)
option in
the given input’s settings. In this case, the input will become activated when the closed
contact between the given input (
IN1
…
IN4
) and the
V-
terminal (or the
COM
terminal) becomes
open.
2.2 Connections and wiring
Attention! Do NOT connect the metallic parts of the GSM antenna connector or the
terminals of the device directly or indirectly to the protective ground, because this may
damage the device!
System terminal inputs and outputs:
V+
Supply voltage 12
…24V DC (min. 500mA)
V-
Supply voltage negative
LINE
Simulated phone line output (connect to alarm system phone line input terminals)
IN1
Dry contact input 1
IN2
Dry contact input 2
IN3
Dry contact input 3
IN4
Dry contact input 4
COM
Common negative for the contact inputs and the output (potential equivalent with
V-
)
OUT
Relay output (switches the negative, max. 1A)
