Annunciator with event recorder

October 2009 Data Acquisition & Telemetry

RTK Instruments has introduced an enhanced annunciator with event recording and communications features.

The 725B combined annunciator and event recorder brings together many years of development in alarm technology to offer clients one of the most advanced alarm monitoring systems currently available. It incorporates CAN communication technology with RTK Instruments’ unique multiredundant design to offer a combination of reliability, flexibility and usability coupled with a low cost of ownership. Based on the field-proven 725 series of annunciators, the 725B has been optimised for monitoring critical alarms in simple or complex systems.

Reliability has been increased as RTK’s multiredundant design removes the need for common CPU or common service modules and hence there is no single point of system failure. All alarm cards in the system are automatically able to act as the master controller. For improved illumination, increased reliability and lower operating costs, all alarm windows are illuminated by ultra-bright white LEDs offering a maintenance free solution. The unit can be offered as a standalone annunciator, or with an integrated 1 ms event recorder which allows users to analyse the exact sequence of events following a breakdown. To reduce installation time and costs, it can be supplied with integral universal power supplies to connect directly to 85-264 VAC or 88-360 VDC.

The modular construction provides flexibility in panel designs as it allows units to be assembled in almost any size and shape to suit individual customer requirements. Each alarm channel is fully programmable using the RTK supplied configuration utility and standard USB programming port, allowing users to select from an extensive range of options for thousands of possible configuration combinations. All programmed information is stored in EEPROM giving repeatability, reliability and requiring no battery backup.
