- Barry Thanks for the speedy response.
when the four TIUs display it's usually 1,2,3,5 cannot remember if I have ever seen 4. As far as numbering the TIUs we have two numbered one (one flash),two numbered two, two numbered three, two numbered four and only one numbered five.
Remote access via TIU # 5 is OK as is all other TIUs.
