Introduction

Overview
The NFA-T01ST Addressable Sounder Strobe functions as an alarm warning device designed to alert individuals in the vicinity of a fire emergency, prompting them to take appropriate actions. This unit is a versatile multi-application device, encompassing various types, parameters, and wiring layouts within a single unit. Through Programming Tool, the NFA-T01ST can be transformed into different alarm warning configurations, including sounder-strobe, sounder-only, or strobe-only types. Furthermore, users can customize parameters to meet specific requirements, such as selecting from 17 different alarm tones, choosing between single or dual address modes, and adjusting power consumption to a low current mode through straightforward programming.
The NFA-T01ST Addressable Sounder Strobe is designed in accordance with the EN 54 Part 3 European Standard. Its aesthetically pleasing and unobtrusive design seamlessly complements modern building aesthetics. The plug-in assembly simplifies installation and maintenance for installers. Additionally, the unit is fully compatible with the NFA-T04FP Intelligent Addressable Fire Alarm Control Panel, en-suring smooth addressable communication without any compatibility issues

Installation

Installation Preparation
This alarm warning device 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.

Installation and Wiring

Mount the sounder base on standard one [1] gang electrical back box. Follow the arrow mark for the correct position. Do not over-tighten the screws otherwise the base will twist. Use M4 standard screws.

Connect the wire in terminal as shown in Figure [2&3]. Verify the device number or other device parameters if desired using the programming tool then stick on the label before attaching the sound-er-strobe. The sticker labels are available on the control panel.
Attach the sounder to the base, point the sounder in the base by the mark-line and secure the sounder in that position by rotating it clockwise, until it reaches the next mark line.

Sounder Strobe Configuration

Preparation

The NFA-T01PT Programming tool is used to configure sounder strobe soft address and parameters. This Programming Tool is not included, must be purchased separately. The programming tool is packed with twin 1.5V AA battery and cable, ready for usage once received.
It is mandatory for the commissioning personnel to have programming tool in order to adjust the sounder strobe conferring to the site situation and environmental requirements.

Program a unique address number for each device according to the project layout before placing from the Terminal Base.

Warning: Disconnect the loop connection whilst connecting to the programming tool.

Addressing

Connect the programming cable to Z1 and Z2 terminals (Figure 4). Press “Power” to switch on the unit.
Switch-on the programming tool, then press button “Write” or number “2” to enter Write Address mode (Figure 5).
Input the desire device address value from 1 to 254 and then press “Write” to save the new address (Figure 6). Note: If display “Success”, means the entered address is confirmed. If dis-play “Fail”, means failure to program the address (Figure 7).

Press “Exit” key to go back Main Menu. Press “ Power” key to switch-off the programming tool..

Single and Dual Address Mode
Single address is commonly used to program immediate Evacuate tone while the dual address used for programming Pre-alarm and Evacuate tones respectively in a given period of time.

In Single Address Mode
When in action (Evacuation stage), the sounders will produce visible signal of 1.4 flashes per second at 1±20% Hz frequency and simultaneously audible signal according to the pre-defined tone (Table 1- Tone 14 is the default tone) and will stop if the panel is reset.

In Dual Address Mode

When In action the 1st Address sounder (Pre-alarm Stage), will produce visible signal of 0.7 flashes per second at 1±20% Hz frequency and simultaneously audible signal according to the pre-defined tone (Table 1- Tone 17 is the default tone). This will run continuously according to the pre-defined time unless the panel is being reset before.
When the delay time is over the 1st address sounder will stop then immediately, the 2nd address sounder (Evacuate Stage) will produce a visible signal of 1.4 flashes per second at 1±20% Hz frequency with a simultaneously audible signal according to the pre defined tone (Table 1- Tone 14 is the default tone) and will stop if the panel is reset.

Attach the programming cable to 1 and 6 Terminals of sounder. Press “Power” to switch-on the unit.

Switch-on the programming tool , then press button “3” to enter to Configuration mode (Figure 8).
Input the “1” for Single Address mode or “2” for Dual Address mode then press “Write” to change the setting into the desire mode (Figure 9).

Note: If display “Success”, means the entered mode is confirmed. If display “Fail”, means failure to program the mode.

In Dual address mode, the sounder will generate the unique next higher number for the second address for example: In single address mode the address number is 15, when change to dual address mode the address numbers will now be 15 and 16.

Warning: Dual address mode may cause Duplicate address fault on the panel and may affect the operation of the next device with conflicted address number if not carefully arrange the loop addressing.
