(a) Turn off the power to the siren at the disconnect switch.
(b) Remove the siren housing from the mechanism.
(c) Disconnect the electrical power wiring from the siren motor.
(d) Remove the siren mechanism from the mounting surface. If desired, the legs can also be removed
from the mechanism.
(e) Remove the field-retaining ring from the motor housing.
(f) Arrange two spacers consisting of 4" x 4" (102mm x 102mm) lumber or similar material,
approximately 5" (127mm) apart on a solid work surface as shown in figure 5-2.
(g) Sharply rap the motor housing against the spacers several times until the field drops out of the
motor housing. The motor housing is aluminum die-casting. As a result, it can be broken or damaged.
Therefore, use caution to ensure that the motor housing strikes the spacers squarely as indicated in figure
5-2.
