TTDM ALarm Module

The TTDM alarm and locating modules are designed for use with all TraceTek® sensing cables to detect and locate liquid leaks. When liquid is detected, the TTDM unit sounds an alarm and displays the location of the leak in either feet, metres or zones (defined at the time of installation) on its LCD display. The unit then continues to monitor and will re-alarm if there are any major changes.

The unit directly monitors up to 1500 Metres (5000 Feet) of sensing cable and can monitor up to 128 networked SIM’s (Sensor Interface Modules) or TTDM units. Each event is logged along with time and date to the units non-volatile memory and can be forwarded to a host computer via RS232/RS485, Modbus, 4-20 Milliamp transmitter or clean form C relay contacts.

Once the alarm condition is cleared, the module is reset with a single keystroke. In addition to detecting leaks, the TTDM:

• Warns of fault conditions.
• Indicates when service is required based on built-in, system-wide diagnostic functions.
• Features an events history log that tracks leaks and other events.
• Settings can be customized to suit the user’s application. Software selections include language (English, French, German, or Spanish) and units (feet, meters, or zones).
• No need for calibration or complicated setup procedure.
• Features a NEMA 12, IP 54 enclosure

Design Features:

• Multiple event tracking capability for up to 128 independent sensing circuits.
• Summary relay contacts, LED status lights, LCD information display at the TTDM master panel and designated slave unit’s.
• Event history accessible from the front panel or via the serial port to identify: type of event, location, & other parameters for all sensing circuit events or user adjustments and interventions.
• Complete remote operation & Monitoring through Modbus communications or using operational TT-Supervisor software for windows.

TTSIM-1

The TTSIM-1 Sensor Interface Module monitors up to 5000 feet (1500 m) of TraceTek® sensing cable. When liquid is detected, the TTSIM-1 unit communicates either with a TTDM-PLUS Master Module or directly to a PLC or other host system using the standard modbus protocol. Although massive sensor cable systems are possible with networked TTSIM-1’s, their low cost makes it economical to build very robust systems with many small independent sensing cable segments. No field calibration is required other than a map to show where the sensor cable has been installed.

Design Features

TT-SIM-2

The TT-SIM-2 Sensor Interface Module monitors up to 150 meters (500 feet) of TraceTek® sensing cable. When liquid is Detected, the TT-SIM-2 unit indicates the leak with an LED, displays the location of the leak on its LCD display and switches a relay to provide local voltagefree contact closure. The TTSIM-2 can also communicate to a host monitoring system such as a TraceTek® TTDM-128 or directly to a PLC or other host system using standard protocols.

TTA-SIM Alarm Module

The TTA-SIM has been designed to give a local alarm whilst communicating precise details to a monitoring network. The unit can be used with the full range of TraceTek cables and sensors along with Aquentis probes.

TT-NRM

Description
The TraceTek® TT-NRM Network Relay Module provides the capability to add up to 320 individual alarm relays to a TraceTek TTDM-128 / TTSIM leak detection network. The TT-NRM communicates with the TTDM-PLUS/128 via the same RS-485 network used for TTSIMs. The TT-NRM can be installed in a wide variety of configurations, allowing many leak detection system layout possibilities.

Expandable
The TT-NRM is supplied as a base unit (with power supply, communications interface, DIN rail and end blocks) and separate relay modules. Each relay module contains 2 independently addressable relays. Up to 16 relay modules can be installed on each base unit, and up to 10 base units can be connected to a single TTDM-PLUS. The leak detection network can be expanded at any time with minimal effort.

Versatile
The TT-NRM can be installed in large panels, or wall mounted in its own optional enclosure. TT-NRMs can be centrally located with the TTDM-PLUS, or distributed throughout the leak detection network to minimize wiring costs. The TT-NRM can be used to operate valves, control audible or visual alarms, or interface with other control systems.
