Why customers choose TaskHolt Tools

Upgrade your home safety with the First Alert SC5 Battery Smart Smoke & CO Alarm (SMCO600NV). This 2-in-1 device blends trusted smoke and carbon monoxide detection with modern smart features, delivering alerts to your phone and compatible hubs whether you’re at home or away.

Engineered for everyday life, the SC5 combines two essential detectors in one compact unit. It uses Precision Detection Technology to help reduce nuisance alarms while delivering early warning, giving you a clear signal to respond when it matters most.

Smart alerts that travel with you

When smoke or CO is detected, the alarm sends real-time notifications through the First Alert app. You’ll know not only that something is happening, but where it’s happening, enabling faster decisions in busy households or during travel.

  • Push notifications to your phone for smoke or CO events
  • Voice alerts that announce the type and location of danger
  • Heads-Up warnings to guide your next steps

Interconnected protection for the whole home

Interconnectivity creates a coordinated safety net. If one compatible alarm sounds, all connected units in the home sound, increasing awareness across rooms and floors without having to check each device.

  • All connected alarms sound together when one detects danger
  • Compatible with Nest Protect Alarm to expand coverage
  • Battery status notifications help avoid unexpected chirps

Practical and user-friendly, the SC5 notifies you when batteries are low and delivers a clear voice message about the danger type and location. It slots into existing safety setups with ease, offering a more connected, responsive home environment without relying on hardwired power during upgrades.
