In these sound signalling devices an indicating light having a rated input power not exceeding 10 VA may also be incorporated.

These products are designated as "devices" throughout the remainder of the text.

This standard applies to fixed, portable and plug-in devices for indoor or outdoor use.

In locations where special conditions prevail, special constructions may be required.

NOTE 1 This standard or parts of it may be used as a guide for sound signalling devices having a voltage less than 50 V a.c. or 75 V d.c. Additional requirements for sound signalling devices having a voltage less than 50 V a.c. or 75 V d.c. are under consideration.
