My invention relates to signaling devices being pres

the ?re signals and the CD air raid warning sirens, which
are presently using the same tone, thereby causing public 10

these openings which produces the ordinary siren sound.
Mounted above the rotor is a solenoid 13 having an up
wardly extending armature lid. Extending through the
armature near the upper end thereof is a rod l5 which is
perhaps best shown in FIGS. 3 ‘and 6. The spring 7 is
attached to the rod 3 and normally holds the armature
in its uppermost position, as shown in FIGS. 1 and 5.

A further object of my invention is to produce a de

What I claim is:
1. A siren comprising a tubular element having open
ings in the side thereof; a rotor for forcing air outwardly
through said openings to cause said siren to emit a
normal sound; and electric motor for driving said rotor
at high speed; means for intermittently preventing emis
sion of a normal sound and electrical means for reduc
ing the current ?ow to said motor simultaneously with the
prevention of emission of a normal sound.
2. In an electrically actuated device for giving a warn
ing signal; a source of electric power for actuating said
device; a normally closed circuit including said device,
said source of power, and a plurality of small neon lights
which , when lighted, indicate that said circuit is in op- '
One of the important features of my adapter is the 60 crating condition; and a plurality of manually operable
