A professional-grade hardwired combination smoke and carbon monoxide alarm engineered for the demands of multi-unit residential and commercial building compliance. The BRK SMICO105-AC (1046884) combines ionization smoke detection and electrochemical CO sensing in a single unit, backed by a factory-locked 10-year lithium battery that delivers a full decade of protection with no battery changes required. Smart Interconnect technology links up to 18 compatible alarms throughout the building -- when one sounds, all sound. UL 217 8th Edition listed, dust cover included for construction installations, and hardwired quick-connect plug simplifies installation for licensed electricians.
Key Features:
- 10-Year Factory-Locked Battery Backup: Factory-sealed 9V lithium battery provides 10 years of continuous backup protection with no battery changes required -- eliminating the maintenance burden of annual battery replacement across multi-unit buildings while ensuring protection during power outages.
- Dual Ionization Smoke & Electrochemical CO Detection: Ionization smoke sensing technology is particularly sensitive to fast flaming fires, while the electrochemical carbon monoxide sensor provides early warning of CO buildup -- advanced sensing technology reduces cooking nuisance alarms without compromising safety performance.
- Smart Interconnect -- Up to 18 Alarms: Interconnects with most First Alert and BRK alarms throughout the building. When one alarm sounds, all compatible alarms sound -- supports interconnection of up to 12 smoke alarms and 6 CO/heat alarms for whole-building life safety coverage.
- Latching Alarm Indicator & Test/Silence Button: Latching LED visually identifies which unit initiated the alarm or low battery signal -- simplifying troubleshooting across multi-unit installations. Single-button test and temporary silence function allows fast, one-touch testing and alarm acknowledgment.
Where to Use:
- Multi-Unit Residential Buildings: The professional standard for hardwired interconnected smoke and CO alarm installations in apartment buildings, co-ops, and condominiums where NYC and state building codes require combination alarms with battery backup.
- New Construction & Renovation: Dust cover keeps alarm clean during construction and renovation -- quick-connect hardwire plug speeds installation for licensed electricians across multi-unit projects.
- Hotels & Hospitality: Smart Interconnect ensures building-wide alarm activation in guest corridors and rooms, supporting life safety code compliance in hotel and hospitality applications.
- Commercial & Institutional Buildings: UL 217 8th Edition listing and hardwired interconnect capability meet the most current commercial and institutional fire safety code requirements for combination smoke and CO detection.
