Муқаддима

Барview

  • The NFA-T01LM Loop Extension Module operates on a DC24V power supply and utilizes an internal electrical isolation circuit to achieve real-time isolation and transmission of input and output bus signals, delivering a standard bus waveform. This module enhances the bus’s resistance to interference and helps extend the communication range. It is particularly effective in environments where external interference occurs or where longer communication distances are required.
  • Compliant with EN 54 Part 18 (European Standard), the unit features a discreet design suitable for modern buildings. Its plug-in assembly allows easy installation and maintenance. Fully compatible with the NFA-T04FP Intelligent Addressable Fire Alarm Control Panel, it ensures seamless addressable communication without compatibility issues.

Принсипи кор
The loop extension module collects the bus signal through the bus transceiver circuit, and outputs the control bus output circuit after the MCU processes the standard bus waveform; the signal isolation circuit bus input and output through an optocoupler can extend the bus communication distance and can correct the bus waveform.

Истифода ва амалиёт

  1. The use of the loop extension module must follow the following requirements:
    Meet the technical parameters defined in this specification
  2. After the loop extension module is installed, or in the use of the process to be tested every six months, the test method is as follows:
    1. The fire alarm controller is used to connect the front-end coding device with the extension module, and the coding equipment should be able to log in correctly.
    2. The detector, which is connected to the bus through the extension module is reports to the fire alarm, and the controller should be able to receive the alarm information correctly.

Муомилот ва нигоҳдорӣ
Transport, storage, and handling equipment shall be carried out in a packing condition. Loading and unloadprocessescess must be handled with care to prevent collision damage. StorageThehe environment shouldmaintainedn ventilation, dry, and avoid open storage.

Нигоҳдории умумӣ

  • Пеш аз гузаронидани таъмир ба кормандони мувофиқ хабар диҳед.
  • Disable the loop extension module on the control panel to prevent false alarms.
  • Do not attempt to repair the circuitry of the loop extension module; it may affect the operation to respond to a fire condition and will void the manufacturer’s warranty.
  • Notify again proper personnel after conducting the maintenance, and make sure to enable the loop extension module and confirm if up and running.
  • Perform the maintenance semiannually or depending on the site conditions.

Мулоҳизаҳои асосӣ

  • On-duty personnel should be familiar with the operation of the equipment, not the wrong operation.
  • This module for fire protection products must strictly implement the duty system and the shift in use, and make a running record.
  • Not every half a year is a function of the module test.

Limitations of the Loop extension module

  • The loop extension module cannot last forever. To keep the loop extension module working in good condition, please maintain the equipment continuously according to recommendations from manufacturers and relevant national codes and laws. Take specific maintenance measures based on different environments.
  • This loop extension module contains electronic parts. Even though it is made to last for a long period of time, any of these parts could fail at any time. Therefore, test your module at least every half-year according to national codes or laws. Any loop extension module, fire alarm devices, or any other components of the system must be repaired and/or replaced immediately as they fail.
