GSM/GPRS alarm signal transmitter with IO-expansion

The signal transmission device is assembled with input/output expansion.

It is capable of forwarding signal changes of the input lines, line’s open circuits through the GSM/GPRS network (standard Contact ID format alarms).

The received signals are transmitted by the device to the dispatcher centre, as well as the Customers will be notified.

Through the output lines several connected devices can controlled remotely.

Communication
• Analog voice-call based alarm signaling through GSM to the alarm centre or by phone line
• GPRS transmission (to an IP receiver, to primary/secondary IP)
• Sending life signals through GSM/GPRS
• Generating alarms for signal changes of input lines
• SMS alarm notification (up to 4 phone numbers)
• Remote control by SMS message/phone ringing*
• Various protocols, Contact ID international format, compatibility with several alarm systems

Connection
• 8pcs inputs, sense status changes/generate alarms
• configurable operation mode of inputs, invertable
• galvanically independed voltage input
• contact: short, open circuit, 10kOhm resistor
• 4pcs outputs (remote control/switching)
• Alarm Tip-Ring input (for alarm system)
• Serial connection (configuring parameters)

Safety
• Reliable operation, automatic network recovery
• Easy installation, parametrizing software
• Remote/local configuration/firmware updates
• LED display (inputs/status/failure/signal strength)

Application

• Transmission to dispatcher centre
• Transmitter for alarm systems
• Standalone alarm signaling
• Safety tasks
• Remote control (contact switching, gate opening, industrial control)
• Remote monitoring of input lines
