About the 4902-9717

The 4902-9717 is a non-addressable fire alarm speaker in a rectangular white housing with red FIRE lettering, for surface or semi-flush wall mounting. Its 4 in. cone and multi-tapped transformer give 1/4 W to 2 W output from either 25 VRMS or 70.7 VRMS input, for voice and tone signals. The housing matches TrueAlert strobes and speaker/strobes.

The NEMA 1 rating applies when the speaker is used with the 4905-9941 adaptor skirt on a suitable 4 in. square back box.
