OPERA Smoke Detector / Smoke Detector

OPERA Smoke Detector

The assent to disassemble a smoke detector’s battery housing while teetering on a ladder is an awkward and potentially dangerous chore. Some people never bother to change their batteries. Opera is a smoke detector designed to make battery replacement easier by supplying the battery housing to you. An intuitive cabling system lowers the housing within reach once the battery is almost drained. The annoying, hard-to-ignore, dangling battery will provide incentive for the user to replace his battery and reel the cable back up.The cable system is also activated during a smoke alarm as a snooze option in a non-emergency situation.
