RTK Instruments Series 725 Alarm Annunciator

Product catalog summary
Overview: The Series 725 Programmable Alarm Annunciator is a highly reliable and flexible alarm system suitable for various industries. It features a multi-redundant ASIC design to prevent single points of failure and offers extensive programmability with modular construction.
Specifications: The annunciator supports 1 to 256 alarm channels, with three window sizes and six color options. It can use bulb or LED illumination and is fully field programmable, storing data in EEPROM for reliability without battery backup.
Design and Construction: Its modular design allows for custom assembly to meet specific requirements. The multi-redundant design ensures high reliability, with each alarm card capable of acting as the master controller.
Programming and Maintenance: Programming and maintenance, including bulb/LED replacement and legend changes, can be performed from the front of the unit. The programming module also serves as a diagnostic tool.
Features: Key features include auto-mute, auto-acknowledge, sleep mode for power conservation, and RS485 bi-directional communication for integration with third-party systems. It supports various input voltages and provides multiple relay outputs.
Options and Customization: Optional features include LED illumination, tropicalization, individual repeat relays, adjustable response times, and enhanced ingress protection. The unit can be pre-configured for integration into larger systems.
Applications: Suitable for critical plant alarm monitoring, the Series 725 offers high reliability and flexibility, ideal for unmanned substations and battery-powered applications.
Compliance and Mounting: The annunciator complies with European EMC and LVD directives, is CE marked, and can be mounted in panels, racks, or enclosures.
System Processes: The annunciator operates through normal, abnormal, and acknowledged states, with specific visual and audible indicators, supporting automatic reset and ringback sequences.
Window Size & Layout: The modular design allows for custom window configurations, with each cell measuring 60 x 60mm. Configurations can reach up to 30 cells in width or height.
Dimensions: Dimensions are based on the number of cells, with specific measurements for configurations from 1 to 16 cells.
Film Legends: Customizable acetate film legends for alarm text can be produced using a Microsoft Excel template.
Inputs: The system accepts bipolar inputs for AC or DC voltages, with standard configurations for volt-free contacts or 24VDC powered inputs, and optically isolated inputs.
Outputs: Includes common and repeat relays, with options for individual repeat relays per alarm way, rated for high voltage and current.
Display: Available in small, medium, and large window sizes, with various color options for lamp and LED illumination.
General Specifications: Operates on a nominal 24VDC supply, complying with international standards for immunity, emissions, and safety.
Environmental Conditions: Designed to operate in a wide range of temperatures and humidity levels, with protection ratings for different system parts.
Compliance and Warranty: Complies with ISO9001:2000 and other standards, with a 5-year guarantee from RTK Instruments Limited.

Serial Communication Bi-directional RS485 communication is available as a low-cost option. This can be used to receive alarm information from or transmit to third party equipment. Each alarm channel can be configured to accept alarm inputs from the standard alarm contact or via the communications. The communications can be used to create systems linking two or more Annunciators together as repeat or grouped displays. Sleep Mode Increasingly Alarm Annunciators are used in applications where the primary supply is produced from batteries, typically substations, which are not permanently manned....

Connections All connections are made to the rear of the unit, using two part screw terminals capable of taking 2.5mm Auxiliary Relays Each alarm way can be supplied with an individual repeat relay. Each relay can be programmed to be energised or de-energised on alarm and both normally open and normally closed contacts are available on customer terminals. The repeat relays can be set to follow the alarm logic, follow the field contact or follow the display. CE Marked > Designed within the stringentrequirements of the European EMC andLVD directives ensures that the Annunciatior conforms to the...

Three Horn Relay Outputs (Option 3HN) Rack Mounting RS485 Serial Communications (Option COM) Adjustable Response Time (Option AD*) It is possible to change the operation of the common relays to have three horn relays and a single group relay rather thantwo of each. With this option the methodof programming of the relays remains the same but their operation is altered slightly. The Annunciators can be supplied pre- mounted in standard 19" aluminium mounting plates. A maximum of 7 cells will fit across a 19" front plate. If specified at the time of ordering each channel can be supplied with user...
