Script brushmodel destroyed? in Scripting

Dont know, if this is script problem or mapping one, but I will ask here.
I made script where when trigger is hit, then it destroy glass and plays few FXs. Problem is, that I can shoot the glass and it would destroy it, but I dont want this it happen. Script:

Code Snippet

Plaintext

console()
{
        fire_console = GetEnt("fire_console","targetname");
	explosion = GetEnt("explosion","targetname");
        console_trig = getent("console_trig", "targetname");
        glass = getent("glass", "targetname");

        console_trig SetCursorHint("HINT_NOICON");
        console_trig SetHintString("Press &&1 to Destroy Jammer");
 
	ent = spawn("script_model", console_trig.origin);
    ent setModel("tag_origin");
    PlayFXOnTag(level._effect["console_l"], ent, "tag_origin");

        console_trig waittill("trigger", player);
		fire_console PlaySound("five_switch");
		fire_console PlaySound("grenade_explode");
        console_trig delete();
        glass delete();
		ent delete();
		playFx(level._effect["step2_fx"], explosion.origin);
        playFx(level._effect["step_fx"], fire_console.origin);
}
