Description
The WSS-PR-N00 is a wall mounted sounder fitted with a Visual Indicating Device (VID) behind a RED lens. That indicator is not a visual alarm device: the product is not approved to EN54-23 (Visual Alarm Device) and must not be used as a visual alarm device to provide a primary warning notification of fire.
Where a red indicator is wanted alongside an EN54-3 approved sounder, this non-isolated model takes its power from the loop and mounts on the B501AP base it requires. The casing is white and the skirt is pure white, and LPCB approval covers the product.
The WSS-PR-N00 is a wall sounder VID - an addressable, loop powered sounder for wall mounting, EN54-3 approved, whose Visual Indicating Device (VID) sits behind a RED lens. One limitation is critical: this product is not approved to EN54-23 (Visual Alarm Device) and must not be used as a visual alarm device to provide a primary warning notification of fire.
The unit is not isolated, has a white body with a pure white skirt, requires a B501AP base and sits in the System Sensor Protocol range of addressable AV devices.
Acoustically it reaches 97dB(A) ±3dB @1m under High Volume, Tone 8 @24V, with 32 built-in tones available and rotary decade address switches setting the address on site. LPCB approval applies to the product.
