ELECTRICAL CONNECTIONS 
Disconnect vehicle battery before making any electrical connections. 
Make electrical connections with supplied terminal block plug for siren functions and spliced lead wires for light control 
outputs. Wiring is not supplied. 
Siren Connections 
Electrical connections to the siren section are made 
using a removable terminal block plug located on the 
back. A label on the unit identifies the terminal function.  
You should install the connector on the unit before 
wiring. If the unit needs service the connector can be 
easily removed without unwiring the connector. 
The power supply of the unit must be capable of 
delivering peak currents up to 50 amps for adequate 
short circuit protection and reliable operation. The 
preferred source is directly at the vehicle battery. The 
unit is internally fused. 
Attach leads by stripping 3/8", inserting into connector 
and clamp by tightening screw. Make sure the screw is 
tight and the wire can't be pulled out. Failure to 
adequately tighten the screw can result in improper 
operation or burning the connector and wire. 
Wire Size and Termination - The diagram shows the 
minimum wire size used for each connection, along with 
recommended lead color. If the wire is longer than 10 ft. 
use the next larger wire size. Use only high quality 
crimp connectors for installation on the vehicle.
