8. Remove any metal shavings or debris from the enclosures.
9. Bond the Siren, 2001-AC, and 2001TRBP to earth ground using separate continuous
runs of 6 AWG minimum gauge wire. (Do not “T” from another ground wire.)
Connecting the Siren
The 2001-AC parts list and wiring diagrams are shown in Figures 3 through 5.
• Typical connections between the siren and control unit are accomplished using us-
er-supplied wires. Two 2 AWG wires provide operating power to the siren motor. An
additional 12 AWG wire provides operating power to the rotator motor if required.
• Route the interconnecting cable through the conduit between the siren and the Con-
tactor Enclosure. A three-position terminal block in the siren housing accepts stripped
wire.
• In the Contactor Enclosure, the DC GROUND terminal block TB1 accepts user-sup-
plied 5/16-inch ring terminals, and the relays accept user-supplied 1/4-inch ring termi-
nals. The contactor coils accept user-supplied 1/4-inch spade terminals. These points
provide convenient locations for making all electrical connections.
Connecting the Control Unit (Optional)
The siren controller (purchased separately) must provide a contact closure between each
contactor (K1 and K2) coil and the DC ground, TB1. K2 controls the main siren motor and
can be held on steady or pulsed on and off for various siren sounds. K1 controls the siren
rotator motor and must be held on for the duration of the siren signal if siren rotation is
required.
Connections to the contactor coils of K1 and K2 are made at the C1 positions of each coil
using 1/4-inch spade terminals. (See Figure 3, view A-A.)
Federal Signal FC Controllers are recommended. See the FC, FCH, and FCU Models
Manual (part number 255294) for installation instructions.
