Installation
UltraVoice (UV)
Electrical Connections
Install the siren electrical system in compliance with local electrical codes
and NEC recommendations. Federal Signal also recommends that all user-
installed conduit connections enter from the bottom of the cabinet. Disconnect
all power and read all warnings at the beginning of this manual and on the
batteries before making connections.
The UV controller must be solidly connected to an earth ground. If the siren
is installed in a building, ground the system to a metallic object known to be
grounded. For pole mount installations, drive a metal rod or bar at least 8 feet
into the ground, as close as practical to the base of the pole. Use a separate,
continuous 6 AWG or larger wire from the siren frame to ground and from the
cabinet of each siren control system to ground.
NOTE
: Seal and protect conduit connections to prevent water entry and corrosion in the
Control Cabinet.
Power Connections
To connect the wires in the Control Cabinet, do the following:
1. Route 1/2 inch conduit (steel preferred) between the user-supplied, fused
disconnect switch and the conduit-fitting hole in the bottom right-hand of the
Control Cabinet enclosure. Use weatherproof switches, electrical boxes and
connectors to prevent water entry and corrosion.
2. Route two user-supplied power wires and a ground wire through the conduit that
was just installed between the Control Cabinet and the fuse disconnect box. Use
wires no smaller than 14 AWG.
3. Connect the ground wire to the green and yellow DIN mounted terminal block
or the cabinet ground stud. Verify the appropriate siren model was purchased.
240 Vac models contain a step-down transformer pre-wired to the DIN rail
located on the right side of the Control Cabinet.
4. Connect the two ac power wires to the DIN mounted terminal blocks labeled L1
and L2.
5. Connect the power wires and the lightning protector to the ac disconnect box per
instructions provided with the lightning protector and governing electrical codes.
