Overview
What it is and how it fits the system.
The Morley WSO-PR-I00 is an EN54-3 approved addressable wall-mounted, loop-powered sounder in red with built-in isolation. It uses the System Sensor protocol for intelligent AV devices, offers 32 built-in tones with rotary decade address switches, and includes an anti-tamper feature. A highly efficient piezoelectric transducer keeps current consumption low, and an optional IP65 rating is available.
Technical overview
WSO-PR-I00 is a Morley Addressable Devices addressable wall-mounted, loop-powered sounder with built-in isolation, designed for intelligent AV systems using the System Sensor Protocol. It features 32 built-in tones selectable via rotary decade address switches and incorporates an anti-tamper mechanism for enhanced security. The device uses a highly efficient piezoelectric transducer to minimise current consumption while maintaining reliable audio output.
EN54-3 approved and LPCB certified, the WSO-PR-I00 is available in red with an optional IP65 rating for increased environmental protection. Its compact dimensions measure 64mm in height and 121mm in diameter, with a weight of 238g. Compatible with addressable fire alarm systems employing loop-powered intelligent AV devices, it supports straightforward integration where physical wiring details are specified in the installation manual. An alternative variant without the integral isolator is available as WSO-PR-N00.
