Installation Instructions
ATTENTION: Read these installation instructions carefully before installing the device. This manual is subject to change without notice.
Warning: Power off the loop circuit before installing the SensoIRIS WSST addressable sounder!
- Choose the proper place for installation of the device.
- Set the device address using the SensoIRIS Programmer or directly from the addressable fire panel. The address must be in the range from 1 to 250.
- Mount the fire base (e.g., B124 for ceiling/wall, WSB IP65 for wall) on the ceiling or wall of the protected premises using appropriate fixings.
- Connect the base to the fire panel using the provided wiring diagram.
- Insert the device into the base and rotate clockwise until it drops into place. Align the short mark on the base with the mark on the sounder body. Continue rotating the sounder until its mark coincides with the long mark on the base; a click will be heard.
- Program the device parameters via the control panel: Navigate to System -> Programming -> Devices -> Loop. Find the installed sounder by entering its address, loop, and zone number. The panel will automatically recognize the device type. Use the 'MORE' button to access additional settings.
- Test the sounder and strobe for proper operation.
Warranty
All devices carry a warranty valid from the date of manufacture. The date of manufacture can be identified by the code marking on the back of the device, printed as YY MM (Year-Month). For example, "20 07" indicates manufacture in July 2020.
For warranty service, please contact your local distributor.

Diagram Descriptions
A-weighted Sound Level Diagram
This diagram illustrates the sound pressure level distribution in decibels (dB) around the device at different angles. It shows that the sound output is directional, with higher levels measured at certain angles (e.g., 0°, 45°, 75°, 105°, 135°, 165°).
Key levels indicated:
- ~87dB @ 1m
- ~88dB @ 1m
- ~89dB @ 1m
- ~91dB @ 1m
- ~96dB @ 1m
- ~97dB @ 1m
EN 54-23 VAD Coverage Diagram
This diagram represents the coverage volume for the Visual Alarm Device (VAD) function, classified according to EN 54-23 as W-2,4-6. It shows the spatial distribution of the light signal emitted by the device, indicating its effective range and coverage pattern.
Mounting and Wiring
Base B124 / Mounting: The B124 base is designed for ceiling or wall mounting. An 'UP' indicator on the base shows the correct orientation. The sounder unit attaches to the base via a twist-lock mechanism, requiring alignment of marks and a click to confirm secure fitting.
Address Programming: Device addresses (1-250) can be set using the dedicated SensoIRIS Programmer or directly via the fire alarm control panel's programming interface.
Wiring Diagram: The device connects to the fire alarm loop via terminals labeled '+Loop' (positive), '-Loop' (negative), and 'Earth'. An 'RI' terminal is also present, likely for a Remote Indicator.
