The CWS100 Conventional Wall Sounder forms the core of our modular alarm device range. The unit can either be used as a standalone conventional device or as an intelligent unit by the addition of a wired module (ALWS-MOD) or wireless module (SGWSMOD). All devices are weather proof, therefore this combined with the modular approach means the majority of applications can be achieved with very few stock components. The unit is equipped with 3 levels of volume adjustment and 32 recognised tones which can be set via the control equipment or locally at the sounder.
