i am sorry but thats the way it works for all monitored installtions.
we do not, and never have done had a monitored system on user reset, remote reset yes, but never user reset.
its is unfortuently for you, and others that have a system fitted and then decide that you don't or do not need this facility, then complain about the charges.
we as an organisation have to work to a set set of regulations in regard to what we fit and how we fit it.
you will have to contact your original provider or another company to rectify what you have done, because you decided to change the battery, you caused a TAMPER fault (which is engineer reset only), if you had posted on the site earlier we would have informed you not to open the box!
sorry but you are stuck with it, or you can completely remove the system and fit another one of your choice, but that is up to you.
some thing to think on as well;
your washing machine goes faulty,
you call a repair man out to it,
he fixes it, gives you a bill,
you say its never gone wrong in the years you have owned it
do you pay the bill or what?
its the same for us in this industry
we go to calls and find the client has tampered with the system, we fix it and invoice them
they pay
simple
its not down to the industry, so please don't blame us, if you realised what we have to do to just fit a system (paperwork wise) it would scare you,
and the constant updating of our skills, who do you think pays for it?
you the client
