Electronic Siren (490-0488F) Wiring Faxback Doc. # 6595 Black wire: Connect to the negative (-) terminal of a 12-volt DC power source. Red wire: For the rise-fall sound, connect to the positive (+) terminal of a 12-volt DC power source. Green wire: For steady sound, connect to the positive (+) terminal of a 12-volt DC power source. If your alarm system provides separate outputs for different alarm situations (fire and intrusion, for example), you can use a different alarm sound for each alarm situation. Connect the red wire to one alarm output and the green wire to the other. The negative (-) connection is usually common. Warning: Sale and use of siren for mobile applications is prohibited in California and certain other states. Check local regulations before installing this Siren. (LB/all-07/11/94)
