Connecting the Contactor Enclosure
To connect the siren to the Contactor Enclosure:
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 bot-
tom of the siren rotator housing.
2. Install a 1-inch user-supplied electrical conduit between the conduit fitting in the bot-
tom of the siren rotator housing and the conduit fitting at the bottom of the Contactor
Enclosure.
3. Route the two 2-AWG siren motor wires and the one 12 AWG rotator motor wire
(user-supplied) from the siren rotator housing to the Contactor Enclosure through the
conduit.
4. Connect the 12 AWG wire (48 Vdc) from the terminal block in the rotator housing ter-
minal 1 to the rotator control relay K1-2 (user-supplied 1/4-inch ring terminal required).
(See Figure 3, View A-A).

nal 2 to the rotor control relay K2-2 (user-supplied 1/4-inch ring terminal required).
6. Connect a 2 AWG wire (common) from the terminal block in the rotator housing termi-
nal 3 to TB1-1 in the control box (user-supplied 5/16-inch ring terminal required).
