You could just do it like this in the global section:

    geo $maintenance {
                default 0;
                80.15x.yy.zz/29 0;        # your IPs still allowed
                80.15x.yy.zz/29 0;        # another bunch of allowed IPs
    }

and in the server section add this:

    if ($maintenance) {
       rewrite ^(.*)$ /yourmaintenancefile.html last;
    }

When you want to start maintenance just switch the "default 0;" to 
"default 1;" in the $maintenance block and reload your nginx.
