ProLine 4G provides a simulated line via a GSM/4G network, which can be connected to the alarm center, elevator or telephone exchange via the TIP RING output. In addition to the 48V line voltage, the line substitute also outputs the 72V ringing voltage.

The TIP RING connector connected to the alarm center:

  • receives the Contact ID code and transmits it via the GPRS/LTE network to the monitoring station, up to 4 IP addresses
  • contacts with the monitoring station via voice call and provides the line for communication via GSM/4G network
  • it takes a Contact ID code and translates it into an SMS, then sends it to a maximum of 8 phone numbers. It can pair 250 zones and 250 events so that you can read the event and the associated zone via SMS. We can choose which phone numbers to send the SMS message to per event

It has 2 inputs, which can be in NO/NC state. In the event of an incoming signal, send an SMS or voice call to a maximum of 8 phone numbers to be notified and the Contact ID to the monitoring station on the GSM/LTE network. A notification event can be an input signal, tamper, power monitor, or life test signal transmission.

The output can be controlled with a free voice call from unlimited numbers without phone number identification or from 1000 phone numbers with phone number identification. The output can be one-state timed, i.e. monostable (up to max. 65000 sec) or two-state, bistable. The module can be expanded with a relay output, such as 1 or 3 relay outputs (EXP Relay or EXP Relay3).

The device measures and logs the GSM network strength values ​​every hour, which the software can display on a graph. The device can store 16,000 events (input, output, GSM network strength, power failure, and output control based on call number).

SIM functions include forwarding incoming SMS to a pre-programmed phone number and displaying a warning message about the SIM card's expiry.

The optional battery (ProBattery) enables the indication of a complete power failure and the operation of the device for approximately 4 hours.

Programming can be done via SMS or computer using the ProRead software (USB or Bluetooth).

Application areas:

  • Analog telephone line monitoring and simulation
  • Line simulator for alarm centers
  • Control: gate garage door and barrier control, arming/disarming alarm center
  • Home automation (air conditioner, sauna, lighting)
  • Monitoring electricity network (230V) along with notification sending about its change
