The Loop-Powered Visual Indicator is designed for indoor use and can be connected to detection systems using XP95 or Discovery detectors and control panels using the appropriate software. The visual indicator is used as a supplement to sounders in situations where there is a risk that sounders will not be heard. The visual indicator can also be used to give a ‘staff alarm’ where the use of sounders is undesirable. e.g. in TV or radio studios, cinemas, theatres, hospital operating theatres and high dependency units or care homes.
