First Alert is a life-safety brand for smoke, carbon monoxide, and fire detection. openHAB is local automation software for people who want deeper smart-home control. Neither is a complete intrusion alarm by itself.
Quick Verdict
Choose First Alert when the job is smoke, CO, or fire detection. Choose openHAB when the job is local automation across mixed smart-home devices. Use a dedicated alarm system when the home needs door/window sensors, arming modes, sirens, monitoring, and emergency response.
First Alert vs openHAB: Key Differences
