NORDEN NFA-T01LM Loop Extension Module Instruction Manual

Sauniuniga Fa'apipi'i
This interface module must be installed, commissioned, and maintained by qualified or factory-trained service personnel. Ensure compliance with all local codes in your area or standards like BS 5839 Part 1 and EN54.

Fa'apipi'i ma Uea
1. Install the loop extension module where anti-interference is needed or for extending bus communication distance within 1000m.
2. Securely fix the module with screws in a suitable location.
3. Refer to the external wiring terminal diagram for proper wiring.

Loop Extension Module Configuration

Outline Dimension Chart
Refer to the outline dimension chart for the physical size of the loop extension module.
Fa'avae Galuega
The loop extension module collects bus signals, processes them through the MCU to output a standard bus waveform. The signal isolation circuit extends the bus communication distance and corrects the bus waveform through an optocoupler.

Fa'apipi'i

Sauniuniga Fa'apipi'i
This interface module must be installed, commissioned, and maintained by a qualified or factory-trained service personnel. The installation must be installed in compliance with all local codes having jurisdiction in your area, or BS 5839 Part 1 and EN54.

Fa'apipi'i ma uaea

The loop extension module is used for anti-interference. When used outside the site should be installed in the presence of disturbances, such as the shielding effect of the iron shell. , extension module as an extended bus communication distanc, is used; it should be installed at the output end of long long-distance bus controller within 1000m; fixed by screws, installed in the room.
The external wiring terminal diagram is shown below:
- D1, D2: 24V nofoaga fa'aoga eletise
- I1, I2: Bus input terminal
- 01, 02: Bus output terminal, 01 is the positive, 02 is the negative.
- Manaoga manaʻomia: no polarity signal, two buses using RVS twisted pair,
- Sectional area≥1.0mm²;
- DC24V power using BV line, Sectional area≥1.5mm²
  NOTE: The NFA-T01LM cannot be used in the loop.

Loop extension module configuration

Outline dimension chart

Fa'avae galue
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.

Faʻaaoga ma le Faagaioiga

The use of the loop extension module must follow the following requirements:
Meet the technical parameters defined in this specification
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.

Taulimaina ma le teuina
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.

Tausiga Lautele

Fa'ailoa i tagata faigaluega talafeagai a'o le'i faia le tausiga.
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.

Manatu taua

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.
