Home Alarm question

every system is a little different,

When you cancel monitoring it does not impact the alarm system- only the alert that goes to the company.

Everything else should work the same

Now if you have one of the newer high tech systems there may be some variance

First, make sure that you actually own the equipment and haven't been just leasing it - some of those contracts can be pretty scurrilous! If you are specifically not on a month to month basis now, the contract could have even been set up to renew automatically for an arbitrary period of time and you might have to notify them in writing during a particular time frame!

After the monitoring contract is cancelled, it is likely that the system would be able to be programmed to act as a local alarm system, meaning that there would not be any notification to a monitoring service for any reason - but it would still function locally, siren would sound, beeping on door/window opening, etc. If it is connected to a landline, I would disconnect it from the landline because a problem with the system could cause the landline to be unusable.

You may need someone to make a minor change to the programming if the system had been set up to beep or notify you via the keypad if it could not get in touch with the monitoring service, as many or most monitored systems check in with the monitoring service once a day.
