I have an existing Risco alarm system which include 3 wireless internal detectors upgraded 4 years ago. My alarm company doesn't 't want to maintain them anymore because they are out-dated and want me to upgrade again. Can't afford that right now but need to replace the batteries ( they were replaced 2 yrs ago). Can I go to another company or am I locked into the company that installed my alarm.
Thanks for the help
