How can i make the /opengate command works only for lv3 admin +

if (strcmp("/opengate", cmdtext, true) == 0)
{
if(IsPlayerAdmin(playerid))
{
MoveObject(SFPDgate,-1571.80, 654.16, 6.08, 1.1);
new string[256];
new name[128];
GetPlayerName(playerid,name,12;
format(string, sizeof(string), "%s has opened the SFPD gate!",name);
SendClientMessageToAll(0x0AFF0AAA, string);
}
else
{
return SendClientMessage(playerid,0xFF0000AA,"/opengate is an RCON command."); //If not RCON
}
GameTextForPlayer(playerid, "~G~gate opening...", 3000, 5);
return 1;
}
