Mounting the Siren
The Model SST3-MV can be attached to any relatively at
surface or to a variety of electrical wall boxes. A four-position
plug is supplied for electrical connection. In addition, two #8-
32 x 3-1/4 inch slotted machine-screws are included to attach
the unit to a four-inch square electrical box. After the mounting
method and location have been selected, follow the procedure in
the appropriate section below. For clarity, The speaker portion of
SST3-MV is not shown in the illustrations.
The speaker and its base assembly provides three degrees of
freedom, allowing the siren to be oriented for any coverage pattern
desired. The angle is adjusted with hand-tightened nuts that require
minimal torque to maintain the position of the siren.

For AC Operation
To connect AC power to the siren:
1. Make operating power to the siren is off.
2. See Figure 4. If the siren is to be operated from an AC
source, set the voltage selector switch SW1 on the siren
PCB to the desired source voltage.
Figure 4 Settings on the siren PCB
3. Connect the AC power leads to the 120/240 Vac terminals
of the four-position connector plug supplied with the siren
by inserting the stripped ends of the wire into the connector
as far as they can travel. Make sure the supply lead
insulation is ush with the connector.
NOTE: If you are using stranded wire, be sure that there
are no loose strands outside the connector plug that could
touch the adjacent lead and cause a short circuit.
4. Plug the connector into the receptacle provided on the
printed circuit board.
