Listec® LIST® Controller

LIST Controller

The LIST® Controllers, with its ARM9™ embedded processor and two secondary processors, is the new generation control and evaluation unit for LIST® systems. The three processor system allows rapid and reliable recognition, detection and signalling of fires. One or two sensor cable lengths or group of sensor cable branches may be connected to the controller, which performs the cyclic addressing of all connected sensors to receive actual temperature values with a high resolution and an exceptional recurring accuracy.

In case of a temperature increase, within programmable levels, the recognition of a fire is indicated. An alarm is given, if a differential alarm threshold is exceeded or if a maximum temperature value is reached.

Both alarm thresholds are independantly programmable for up to 254 zones.

The LIST system reaches a high sensitivity due to the fact, that the temperature is measured with a resolution of 0.1°C. The proven software algorithms guarantee the reduction of any influence through natural temperature variations, thus preventing the risk of false alarms. The unique LIST measuring technology enables an absolutely stable measuring of all sensors with a recurring accuracy of ±0.1°.

An alarm is indicated on the controllers front panel LEDs and on a clear text liqud crystal display (LCD). Alarms are highlighted by a red and faults by orange background lighting in the display.

Alarm signamisation to superordinate systems takes place via potential-free relay contacts and/or through communication interfaces with open data protocols.

The controller can be reset on the front panel, through an external electrical reset signal from the fire control panel or via the communication interface.

Highlights:
  • High-speed analysis of temperature data with three micro-processor technology.
  • Flexible communication via various interfaces.
  • USB (host) interface for easy transmission of maintenance data.
  • Clear text display with coloured background.
  • Low power consumption.
  • Modular system for easy checking and repairs.
  • RoHS conformity.
  • Long life-span of all components.
  • 100Mb/s LAN interface for rapid data transmission.

Menu Keys

Audible Alarm

5 keys for the menu navigation to display messages, parameters, etc.
The controller gives an audible alarm while unacknowledged fire or fault alarms are present; the sounder function can be disabled generally.

Alarm Zones

Fire Recognition

Up to 254 zones may be defined by software. The number of sensors resp. the length of each alarm zone is independently selectable.
A fire recognition is signalled if the increase of temperature has passed a programmable level of the pre-settable threshold.

Alarm Criteria

Fault Recognition

Alarms are initiated, if an absolute of differential alarm threshold is exceeded. A frost alarm can be generated, if the temperature falls below a set threshold. All alarm thresholds can be programmed individually for each alarm zone.
Faults in the sensor cable, e.g. a defective measuring point, are generally recognised and shown within 10 seconds. All faults, including those on the controller, are stored in the internal messages list.

Security

Interfaces

A password is necessary for any changes to settings and parameters. Various groups of operators (e.g. for inspection, maintenance or service) may have access through different password levels.
  • COM 1: Master/slave interface for networked LIST systems.
  • COM 2: RS-232 interface for the connection to superordinate systems via data protocols (up to 115200kb/s).
  • COM 3: RS-232 interface for programming via the LISTterm software (up to 115200 kb/s).
  • Ethernet: for fast data transmission in networks (10/100Mb/s, TCP/IP).
  • USB Host: for the storage of maintenance information and data on to a memory stick; access on the front panel.

Data Protocols

Connections

Public data protocols enables interconnection to other control systems:

  • MODBUS/JBUS
  • MODBUS TCP
  • IEC 60870-5-104
  • 3964R
  • SK 1702

Lock connectors for all connections are situated on the rear panel.

The basic version has one connection for the sensor cable (SEC A). A second, optional, connection (SEC B) can be used for:

  • a second independant sensor cable.
  • the looping back of the first sensor cable.
  • a second sensor cable with RDT function (redundancy) in combination with a second controller and the Data Management Unit.
