Ademco Inc. 1046778 Combo Smoke Co Alarm 120V

Product Description

The ADEMCO INC. 1046778 is a hardwired combination smoke and carbon monoxide alarm designed for residential installation by licensed electricians and fire-safety professionals. It operates on 120 volts with a battery backup that maintains monitoring during power outages. The unit uses photoelectric sensing technology for smoke detection and delivers voice alerts that identify both the type of threat and its location, giving occupants clear, actionable information instead of a generic alarm tone. A single-button control on the bottom of the unit allows for silencing false alarms and initiating self-tests.

This combination alarm is suited for residential applications where local code requires both smoke and carbon monoxide detection in a single unit. It connects with other compatible BRK and First Alert alarms, enabling a whole-home interconnected detection network where triggering one unit triggers all connected units simultaneously. The hardwired design makes it appropriate for new construction and retrofit projects where a 120-volt supply is available at the installation point.
