you could hook up anything....you could use the siren's source as a switched source for a relay and run anything off the relay.

as long as the tank was pressurized, anything electronic can be tripped in the car from an alarm.

right the alarm sirens trigger just triggers a relay, you can use anything you want, you couls put on air raid sirens if you want

Ya like they said above. Im sure you know train horns are air powered. Just gotta set up some sort or relay system. Not sure how the horns work really but im thinking it wont be totally easy, but possible with some time. That would be loud as ***

air valves are just 2 wire, power and ground. Take or tap into the hot on the siren and ur set. The real problem i see is air horns eat up a decent amount of air and ud be out real quick

With how sensitive most alarms can be, expect to have something large and heavy placed through your windshield if you install this.

Why not get a 2 way alarm, don't hook up any siren/horn, and don't hook up the parking lights. They thief will have no clue that you're car has an alarm, but you're pocket will be vibrating. You can go and catch him in the act and threaten/attack him with your baseball bat or nine, whichever you prefer.

I guess that's what the train horn would be for. We all know that we pay no attention to alarms when we hear them. I guess it would be best to have a switch to enable the relay that would control the train horns. That way, if you know you're parking where you won't be within the given distance for your 2 way to work, you can flip the switch and have the alarm sound. Otherwise, you could leave the switch in the other position.
