General Description

Natron WSS is a wireless addressable fire alarm sounder with strobe, designed for operation with Natron series wireless expander modules*. The fire sounder is equipped with 360˚ visible strobe LED indication and a built-in sounder for signalization in case for announcing of events – fire alarm and finding the place of installation. The operation of the strobe and sounder is programmed from the sounder’s menus (addressable panel or expander module). Natron WSS is a VAD (Visual Alarm Device) compatible with a deep wireless fire base for wall mounting. For prevention of unauthorized disassembling or removing, the sounder can be locked to the fire base. The fire sounder is equipped also with a tamper switch for self-protection of the box. Natron WSS is designed for indoor installation. Refer to the installation manuals of Natron WE-C, Natron WE-A and Natron WE-A/C wireless expander modules for detailed information about the programming menus and other details.

PCB Elements

The PCB of Natron WSS is factory mounted and is accessible after disassembling the sounder from the wireless fire base – see item 3

1. Enroll button. The button is used for the following actions:
   • Enrolling the sounder to the expander module.
   • Checking the signal strength.
   • Reset the sounder.
2. Power Batteries CR123A 3V
   • Attention: Use only batteries from the same type!
3. Bi-color operation LED (green/red). The LED is used for following the actions during enrollment, reset and checking the signal strength.
4. Tamper switch

Description of Tone Types

Natron WSS supports 32 different alarm tone types. The tone type is set from the programming menus of the expander module (conventional fire alarm systems) or programming the sounders mode in the menus of the addressable fire alarm panel. The sound volume level varies with the tone type selected. The main tone type of Natron WSS is 27.

Enrolling in Expander Module

1. Remove the wireless firebase to access the PCB with the batteries compartment. If the device is not new, perform a reset as described in item 7.
2. Enter in programming mode of the Natron expander module. Select ADD DEVICE menu and press ENTER button. A list of already enrolled devices is shown on the screen with an order number and type of the device.
3. Scroll down to find a free address to enroll the sounder. Every free address is labeled as EMPTY.
4. Press the ENTER button. Message SEARCHING >>> (arrows are blinking) appears on the screen showing that the module is scanning for signals from a wireless device in its covering range.
   • Note: If there is no signal from the device in a 2-minute period, the expander module will exit automatically the programming mode.
5. Power on the sounder. If the device is new just remove the protective folio from the batteries – the enrolling process starts automatically. If the device is powered and reset – single press the ENROLL button. The operation LED (item 4, position 3) starts flashing in red.
6. In case of successful enrolment, the operation LED flashes 3 times in green, and the message DONE appears for a while on the screen of the module. The sounder is added to the list as WSS type.
7. Test the signal strength between the sounder and the expander module. Single press the ENROLL button and wait for the operation LED indication:
   • 3 flashes in green – excellent signal strength;
   • 3 flashes in orange – good signal strength, but, if possible, change the place of installation;
   • 3 flashes in red – poor signal strength and it is obligatory to change the place of installation. You can also check the signal quality for the device in the DEVICE RSSI menu of the module – item 8.
8. If the signal quality and strength are excellent or good, you can proceed with mounting.
9. Use appropriate fixing elements to mount the wireless firebase to the place of installation. Follow the instructions in item 3 to lock the sounder to the firebase if this is needed.
10. Place the sounder in the base and observe the two short marks to coincide. Move the sounder’s body up to hide the marks. Rotate the sounder on the clock side until a click is heard.

Reset the Sounder

If the sounder is not new, you have to reset it before enrolment to the expander module. Check the battery’s condition. It is recommended to change all of them with a brand new one.
To reset the Natron WSS, power it on with the batteries, and after that press and hold ENROLL button for 5-7  seconds. The reset is complete when the operation LED flashes 3 times in green, followed by 1 long flash in red and 1 long flash in green. Next pressing of ENROLL button will start the enrolment procedure for the expander module.

Checking the Signal Quality (RSSI)

The quality of the signal between the sounder and the expander module is checked at the DEVICE RSSI menu of the module. The signal quality is assessed in [dB].

1. Enter the programming mode of the module. Scroll to the menu DEVICE RSSI and press ENTER button. A list of presently enrolled devices is shown on the screen with an order number and type of the device.
2. Find in the list the sounder number.
3. Press the ENTER button. Refer to the table below to read the signal quality on the screen:

You can exit the menu at any time with pressing the CANCEL button.

Finding the Sounder Installation Place and Test

This is a procedure that helps the engineer to find the exact location of every wireless device in the fire installation and test the connection with the module.

1. Enter in the programming mode of the module. Scroll to the menu FIND DEVICE and press ENTER button. A list of presently enrolled devices is shown on the screen with an order number and type of the device.
2. Find in the list the sounder number which you want to locate in the fire installation.
3. Press the ENTER button. Message FINDING >>> (arrows are blinking) appears on the screen showing that the module is scanning for signals from the selected wireless device. The message will change for a while to FINDING DONE in case of success.
4. The sounder will respond with active strobe and short sound signals.
5. The module will exit automatically the finding procedure after 70-80 seconds. You can also stop the procedure at any time by pressing the CANCEL button.

Replacing Batteries

It is recommended to change the batteries after 8 years of operation regardless of their indicated discharge level. Always use only batteries approved by the manufacturer – Panasonic CR123A 3V or others with similar characteristics. Attention: After indication from the panel/expander module for a low battery of a device, the user/ installer must replace the discharged batteries with new ones within one month. The remaining shelf time of the new batteries must not be less than 6 years.

1. Disable the sounder operation to avoid fault messages.
2. Disassemble the sounder as described in item 3.
3. Remove the old batteries and place the new as observe the +/- polarity.
4. Assemble the sounder back in place.
5. Enable the sounder operation.
6. Check the signal quality in the DEVICE RSSI menu of the expander module.
7. Test the sounder’s operability.
   • CAUTION: Do not expose used batteries to fire, hot ovens, or mechanical crushing/cutting as this can result in an explosion. Exposing batteries to extremely high environmental temperatures or low air pressure can result in explosion or the leakage of flammable liquid or gas.
   • DISPOSAL: Follow local regulations regarding the disposal of the batteries.
