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 bottom of all
enclosures.
Solidly connect siren units and control units to an earth ground. If the
siren is installed on a building, ground the system to a metallic object
known to be grounded. For pole mounted installations, drive a metal rod
or bar at least eight feet into the ground, as close as practical to the
base of the pole. For maximum protection, use a separate, continuous
6 AWG or larger wire from the siren frame to ground and from the
enclosure of each siren unit to ground.
Connecting the Siren
The 2001-AC parts list and wiring diagrams are shown in Figure 4 Motor Starter
Enclosure Parts List, Figure 5 Motor Starter Wiring, and Figure 6 Typical Wiring
Diagram.
•
Typical connections between the siren and control unit are accomplished using
user supplied wires. Two 2 AWG wires provide operating power to the siren
motor. If required, an additional 12 AWG wire provides operating power to the
rotator motor.
•
Route the interconnecting cable through conduit between the siren and the Motor
Starter Enclosure. There is a three position terminal block (shown in Figure 7
Terminal Block in Rotator Housing) located in the rotator housing of the siren
that accepts stripped wire.
•
In the Motor Starter Enclosure, the DC GROUND terminal block TB1, accepts
user supplied 5/16 inch ring terminals and the relays accept user supplied
¼ inch
ring terminals. The Motor Starter coils accept user supplied ¼ inch spade
terminals. These points provide convenient locations for making all electrical
connections.
Connect the siren to the Motor Starters, as follows:
1. After drilling or punching an appropriate sized hole in the enclosure, install a 1
inch user supplied electrical conduit fitting in the bottom of the enclosure and in
the bottom of the siren rotator housing.
