Description
The WSS-PC-N00 answers both halves of a fire alarm output from one wall position: its sounder is EN54-3 approved and its Visual Alarm Device (VAD) is EN54-23 O class compliant, coverage coded W-1.9-1.9.
This is the version that is not isolated, so the device itself carries no isolator. It is loop powered, mounts on a required B501AP base, and shows its alarm as a red flash behind a clear lens.
The WSS-PC-N00 is a wall sounder VAD, pairing an EN54-3 approved sounder with a Visual Alarm Device (VAD) that is EN54-23 O class compliant (W-1.9-1.9). It is wall mounted, addressable, loop powered and not isolated.
The visible warning is a red flash behind a clear lens, and the wall mount body is white with a pure white skirt. A B501AP base is required, and the device is a System Sensor protocol addressable AV device.
The sounder is rated 97dB(A) ±3dB @1m, measured at High Volume on Tone 8 @24V, and a library of 32 built-in tones is on hand. The device is addressed on site by rotary decade address switches and is LPCB approved.
