A breakage detection device for a UV disinfection system comprises a pneumatic line 2 attached to the end adapter 3 of the quartz sleeve 1 enclosing the UV light source. The pneumatic lines are attached to a manifold (fig. 2) via a non-return valve (fig. 2). A pressure switch is attached to the line, which detects a rise in pressure if the sleeve is broken. Alternatively a pressure switch may be attached to each of the pneumatic lines. Relay contacts (fig 2) activate the alarm.
