Strobe Lights W/ Alarm

ok how can i turn on my storbe lights when my alarm is triggered?

i have the whelen type police strobes.4 in the back and 2 in the front. im also adding about 4- 6 more in the fronts

so what you think, i have a couple of ways i might do it but want to see if u guys have anything easier and bette

o btw i dont want to trigger it off the siren. i only want them to go on when the allarm is tripped not when i activate and deactive my alarm

thanks

I am doing the same thing you are. The only way I could do it was to use the siren wire off the alarm and hook that up to a delay relay to it would delay the current for about 2 seconds.

is it bad to pulse the strobe lights though

i d rather have something constant, i wasthinking coming off my horn honk caseu that only goes off 8 seconds after the alarm is trigger, i was gonna use a pule timer relay to hook it up so i can ajust the time

what you guys think

you can use the siren output but also use the ground when armed output. 

your will need a relay to do this. here is what you do: 

siren output (+) to 86

ground when armed output (-) to 85

12 volts to 87

30 goes to your strobe lights.

by doing it this way the strobe lights will not flash unless the alarm is armed.
