Installation
UltraVoice Indoor Controller (UVIC)
Electrical Connections
Install the siren electrical system in compliance with local electrical codes
and NEC recommendations. Federal Signal recommends that all user-installed
conduit connections enter from the bottom of the UVIC cabinet using the
supplied conduit knockouts. Disconnect all power and read all warnings at the
beginning of this manual and on the batteries before making connections.
The UVIC cabinet must be properly connected to an earth ground. The
cabinet contains an external 3/8 inch ground stud for making this connection.
Alternatively, a DIN mounted grounding block is provided inside the UVIC
enclosure.
If an outdoor antenna is used, install a separate antenna ground.
Externally installed antennas require a dedicated ground to either a ground
rod or building steel below grade in addition to the UVIC cabinet ground.
Verify the AC voltage requirement for the UVIC model being installed. 240 Vac
versions of the UVIC controllers have a “240” suffix in the model number
shown on the label located on the cabinet door. All other UVIC models are to
be wired to 120 VAC.
DIN Rail Terminal Blocks
These points provide a convenient location for making electrical connections. Push a
small screwdriver into the square opening in the terminal block to open the contact of the
block. With the wire inserted, the block clamps the wire with a spring-loaded connection
when the screwdriver is removed from the terminal block.
Each terminal block accepts bare 12-14 AWG wire. The two fused terminal blocks
labeled F1 and F2 have a built-in disconnect that flips open, disconnects the circuit, and
provides access to the fuse located inside the terminal block.
Wiring Guidelines for the 120 Vac Electrical Service
To wire for the 120 Vac electrical service:
1. Install a dedicated 15 A circuit breaker in an existing breaker panel or install a new
breaker panel if necessary for the UVIC.
2. Install conduit from the breaker panel to a conduit entrance in the bottom of the
UVIC.
3. Route user-supplied 12-14 AWG wires (1 black, 1 white, 1 green - optional) through
the conduit from the UVIC cabinet and the fused breaker panel.
4. Connect the white neutral wire from the breaker panel neutral to the fused DIN rail
mounted terminal block labeled F1-NEUTRAL in the UVIC cabinet.
