Discovery Sounder Visual Indicator Base

Discovery Sounder Visual Indicator Bases are used to provide audible and visual warning of fire and is controlled by the appropriate fire control panel by means of the full Discovery protocol, the particular features of which should be requested from the panel manufacturer. The Discovery Sounder Visual Indicator Base can be used either with a detector fitted or with a cap fitted for operation as a stand-alone alarm device. The Discovery Sounder Visual Indicator Base normally switches both sounder and visual indicator to provide an alert or evacuation signal. The sounder and visual indicator of the Discovery Sounder Visual Indicator Base can, however, be switched independently of each other by the control panel. Detectors and sounder visual indicators are installed in many different environments. The sounder is set during commissioning to one of seven levels of sound, the highest being nominally 90 dB(A). At 60 dB(A) the lowest level is outside of the standard EN 54. It has been included to provide a very local warning for the use of personnel in particular environments, such as nurse stations in hospitals. For full details of Sound Pressure Levels, refer to PP2203 - Sound Pressure Levels, available at www.apollo.co.uk When configuring the Discovery Sounder Visual Indicator Base the adjustment of volume can be configured at the point of installation
