Overview of Model SST3-MV Siren
The Federal Signal Model SST3-MV is an electronic siren that
produces three different high-decibel tones. It features internal
amplication and the circuitry required to produce wail, yelp and
horn tones. Each tone is manually activated from a remote point.
The SST3-MV operates on 24 Vdc, 120 Vac, or 240 Vac. The
NEMA 3R (with backbox) housing is molded from impact-
resistant ASA (acrylic-styrene-acrylonitrile) plastic, making it
resistant to ultraviolet and ideal for indoor or outdoor use. The
omnidirectional swivel-mount system enables the output to be pointed
anywhere within a 360-degree half-sphere.
The Model SST3-MV can be used as a standalone, high-output
audible warning device in any application in which multiple tones are
needed, but voice paging is not required. Typical applications include
emergency warning, start and dismissal, re alarm, general alarm, and
evacuation.

Installation and Maintenance Instructions
Model SST3-MV 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.

13
Installation and Maintenance Instructions
Model SST3-MV Siren
For 24 Vdc Operation
To connect 24 Vdc power to the siren:
1. Make operating power to the siren is off.
2. See Figure 4 on page 12. For 24 Vdc operation, remove
the short-wire jumper (installed in “Wiring for Single Tone
Activation on Power-Up” on page 14.)
3. Connect the positive lead to the (+) terminal and negative
lead to the (-) terminal of the four-position connector.
Wiring for Remote Tone Activation
Make sure operating power to the siren is off.
See Figure 1 on page 8. Apply a dry-contact closure at J4 plug
between the ground (GND) terminal and one of the tone (WAIL,
YELP, HORN) terminals.
Use 18 AWG shielded twisted-pair wires. Strip no more than
0.25 inch of wire insulation from the ends of leads to connect dry-
contact terminals for the remotely-located tone activation between
GND and WAIL, YELP, or the HORN terminal of four-position
connector plug supplied with siren. Make sure the lead insulation
is ush with the connector. If you using stranded wire, be sure that
there are no loose strands outside the connector plug that could
touch adjacent lead and cause a short. Plug the connector into the
receptacle J4 on the printed circuit board.
The selected tone plays when the siren is powered up and the
remote activation contacts are closed.
For proper operation of the remote activating circuit, the total loop
resistance of the GND wire plus the resistance of the tone terminal
wire plus the dry-contact resistance of the circuit should not
exceed 1000 ohms.
By connecting a dry set of contacts for each of the three tones, any
one tone can be activated by closing the appropriate contact:

14
Installation and Maintenance Instructions
Model SST3-MV Siren
• If the contact closures are simultaneously applied to all tone
terminals, the HORN tone will override the other two tones.
• If the contact closures are applied to the HORN tone and any
other tone, HORN overrides the other tone.
• If the contact closures are applied to WAIL and YELP, the
WAIL tone overrides the YELP tone.
Wiring for Single Tone Activation at Power-Up
Make sure that operating power to the siren is off.
The siren can be operated by switching operating power (AC
or 24 Vdc) ON to the siren if a permanent short-wire jumper is
installed between GND and the desired tone terminal of the four-
position connector plug instead of the dry-contact closure.
Connect a 1-inch-long 22 AWG wire between GND and the
desired tone terminal of the four-position connector plug supplied
with the siren. Plug the connector into the J4 receptacle (see
Figure 1 on page 8) on the printed circuit board. Switching ON the
operating power will now activate the siren.
