The TELEPRO-ISP16 Alarm Annunciator is a high-tech product that offers compact, flexible programming and tagging options. It can be easily used in large area protection systems with its ability to work in parallel.

RS-485 Communication Port (optional)

It supports Modbus RTU protocol with the RS485 serial communication port integrated into the galvanic isolation protected device and can be easily integrated into SCADA systems. Instant status information for each entry can be read remotely. Remote commands can be sent to the Horn, Test, Ack and Reset keys.


A 5mm energy-saving LED display that provides an isolated, high-quality image for each input.


With the push buttons positioned on the front panel, auxiliary relay ( Red LED HornGreen Led Buzzer ) selections for each input can be made independently of software, without the need for a Dip Switch. Thanks to this special design, settings can be made safely in an energized state without touching the panel.


With ISPsim™(*) software; relay selection (Horn – Bell), response and release times and ModbusID settings can be performed.
ISA18.1 Sequence Code M (Manual RESET) code is provided as standard.
(*) Note: You can download ISPsimTM software here


All Inputs are opto coupler insulated, varistor protected, common return end and filtered. It fully complies with EU Electromagnetic Qualification (EMC) and Low Voltage Regulation (LVD) requirements. The possibility of false alarms is completely eliminated. The maximum input current is 5mA, the input voltages can be ordered as 24/48 and 110/220 Vdc upon request.


The TELEPRO-ISP8 has two Normally Open 1-FormA type dry contact relay outputs as standard. Outputs can be assigned to HORN or BELL options. All channels can be set to these output options via the software or front panel buttons.
In addition, it has Form C Type NC / NO outputs with common ends that are activated in case of internal system failures. There is also a FAULT relay.


Adjustable response-release times can be adjusted between 3ms and 250ms with software control that offers flexible and reliable operation against magnetic fields that may occur during maneuvers. The response time of the company output is 5ms, the release time is 20ms.


Our power supplies guarantee long-lasting use with their short-circuit, overcurrent/voltage and temperature-protected designs.


It has a membrane-featured, high-quality front panel design. Our easy-to-change printer printed labeling system has a user-friendly design with a screen width of 7×63 mm allocated for each channel.
The windows of each entry are named with the label template provided by TELEPRO® in the computer environment. Label information can be easily changed at any time.


The TELEPRO-ISP8 has a 96x96x75mm panel case. The protection class on the front panel side of our standard cases is IP51. In standard dimensions (96x96x75 mm) and weighing 300 gr, it can be assembled/disassembled quickly and safely with its easy-to-use screw mounting system.


In the TELEPRO-ISP8, 8 potential contacts from relays in the field are activated by connecting them to the device input terminals.

Each channel can be assigned to the HORN or BELL relay according to the operator’s preference. These settings also make a difference in LED lighting. In the BELL assignment, the corresponding channel is illuminated in GREEN, and in the case of a HORN call, it is illuminated in RED. (Optional Red/Yellow Option available)

The connection and other details are detailed in the installation guide provided with our devices.
