The First Alert Combination Smoke and Carbon Monoxide Alarm integrates with existing wiring and features the easy adapter plug, which makes installing the detector quick and easy. The side-load backup battery compartment makes changing the 9-volt battery simple. Tamper-resistant locking pins prevent unauthorized disabling of the CO and smoke alarm.
