Morley WSO-PP-I00 Wall Sounder White Isolated

WSO-PP-I00 is an addressable, wall mounted, loop powered wall sounder with built in loop isolation, finished in WHITE, EN54-3 approved, and LPCB approved as an addressable audio visual device within the Wall Sounder sub-range. It is designed to mount on a B501AP base, which is required for installation, and features a pure white skirt for aesthetic integration in fire alarm systems.

The device incorporates an integral isolator to maintain loop integrity during fault conditions, helping to ensure continued operation of other devices on the same loop. Physical connections must follow the installation manual, and compatibility is strictly limited to the B501AP base for secure and correct mounting. No other accessories or bases are supported or implied by the provided data.

The WSO-PP-I00 delivers reliable audible signalling in compliance with EN54-3 standards, with its loop-powered design eliminating the need for separate power supplies. Its white finish and compact wall-mount form factor allow discreet installation in commercial and residential environments while maintaining full functionality as part of an addressable fire detection system. The integral isolator provides essential fault tolerance, protecting the overall loop performance even if a short circuit occurs elsewhere on the network. This helps ensure that critical alarm signals continue to propagate without interruption, supporting the system's ability to meet life safety requirements under fault conditions.
