GSM KEY  PROFI 3+ 

 is used to remotely cont-

rol electric drives of gates, barriers, doors

and other relay switched circuits using your 

mobile phone. Opening is FREE and is done

by ringing the phone number of the SIM card 

located in the device. 

The GSM KEY PROFI 3+ includes four output 

ports (OUT1-OUT4) for connecting the gate

or gate drive and four input ports (IN1-IN4) for 

connecting the sensors or other peripherals. 

User authorization is performed using the list

of telephone numbers stored in the GSM KEY 

PROFI 3+ memory.

assembly. Only qualified and properly trained 

personnel should install the equipment. Read 

this manual carefully before installing

the device. If a power supply is used to power 

the device, it must comply with the placement 

requirements of the SELV circuits and comply 

with EN60950. If batteries or accumulators are

Now your GSM KEY PROFI 3+ is ready to use 

and you can test its functionality. First, add

the device administrator with an SMS in the 

format: 

AD ADMINIS420xxxxxxxxx 

ADMIN 

(where +420xxxxxxxxx is your phone 

number in the international format, ADMIN

is the group name).

In case of incorrect addition of the Administra-

tor, use the RST button for factory reset.

You can do so by unplugging the device, then 

pressing and holding the RST button while 

reconnecting power to the device. When boo-

ting up, the system recognizes the pressed 

button and performs the required reset. 

The reset process takes about 30 seconds.

of the caller's number may differ inside

the device. Check with your operator.

groups

and operate the device by ringing.

and operate the device by ringing.

ringing.

Individual groups can have any number

of members as long as the limit of 1000 users

is not exceeded. Other groups can be created 

only via administration in the web interface

via PC. The device can be operated by ringing 

the SIM number located in the GSM KEY PROFI 

3+ device. version does not include
