Use and Installation

For environments containing a large number of people when is needed protection against emission of smoke and toxic corrosive gases in case of fire, like schools, offices, theatres, subways, hospitals, worship places, shopping centres and places of public entertainment. Allowed for voltages up to 1000 V a.c. and 750 V d.c., for fixed and protected laying inside lighting devices and switch/control systems. Suitable for installation in recessed or surface mounted ducts for signalling and control circuits. (ref. CEI 20-40, HD 516)
