Overview
What it is and how it fits the system.
The Morley WSO-PP-N00 is a white wall-mount sounder finished with a pure white skirt, supplied without an integral isolator. It mounts on a B501AP base, which is required for installation.
Technical overview
WSO-PP-N00 is a wall-mounted, addressable, loop-powered sounder, specifically a Wall Sounder variant with no integral isolator. It is EN54-3 approved and designed for fire alarm signalling.
The device features 32 built-in tones, with sound output selection and tone choice available either locally or from the fire alarm control panel. Addressing is set via rotary decade switches, and it includes an anti-tamper feature for security. Power requirements are low, and it operates reliably across a temperature range of -25°C to +70°C with maximum 95% relative humidity (non-condensing).
An optional IP65 rating is available for enhanced environmental protection. The unit requires a B501AP base for installation and draws power directly from the loop, with no internal isolator fitted. For physical connection details, consult the installation manual.
