ok that makes more sense. so if I were using a wire from the battery to controll the coil side of the relay, I still need to check the ameture side of the relay for current draw, even if I went with a relay that was probably overkill for the ammount of amps I'm using? I have no problem with...
no, I'd never do that, these units are too expensive to replace. and yeah, sorry about the terminology mixup, parallel is a better term for it.
the sirens are powered by 12 volts, but I'm not sure what voltage/amperage is used on the switches. so am I looking for amperage draw? if so, do...
ok this is the last one before someone replies back. lol dont want to blow up the thread. but since running them in tandem blows fuses and quite frankly, sounded like crap. so here is a little more in detail of what I was thinking, I hope it makes sense to you guys, and doesnt give you a...
sorry, I'm not doubting you at all, relays are a new concept to me, I've never had to use them in my electrical wiring jobs. lol till now I've always just used dual throw switches, its an easier concept for me to understand. lol
well, I plan on using the trucks battery for the remote power for the relays, so would it matter what the sirens were pushing as long as the relays turned on when it took the 12-14 volts coming from the batery?
Hi, I'm seth, i'm a volunteer and paid EMT. I have two identical sirens that, seperate aren't that loud, but together are plenty sufficient. I'm putting them into a truck with limited dash space. I had them ran with dual throw on-off-on switches, but now I dont have room for that big of...
