Thankyou for responding so quickly, I really appreciate it. I'm sorry but I'm having trouble, how do i go about renaming it? do you mean rename the sprite itself? here is what i got in the bsp file. the timing of the siren is what i want. I want the sprite only to be visible while the siren is going.

"origin" "1 -949 -1440"

"renderamt" "255"
"rendermode" "4"
"renderfx" "14"
