using alarm to activate lights 2 switch

i am trying to activate a set of strobes i have wired up my alarm to use a relay to turn the strobes on using an output on my alarms remote which is really cool but i would like to also turn these lights on by using the 12v sorce that turns on the siren for the alarm and still be able to use my remote to turn the lights off and on also so i guess what i am saying is two trigers for one light thanks

Search the information on this site under relays. The easiest way I can think of to do it would be to use the relay configuration to get a constant output, using a triggered input. You should be able to drive the lights off a single relay, if you use diodes to seperate the input triggers.
