Kidde 900-CUAR-V Hardwired Smoke & CO Detector – Voice Alerts, Interconnect, 4 Pack

Overview

The Kidde 900-CUAR-V is a hardwired, 2-in-1 detector that watches for both smoke and carbon monoxide in a single unit. It runs on 120V AC and includes a 2-AA battery backup to maintain protection during power interruptions. With photoelectric smoke sensing and an electrochemical CO sensor, it delivers comprehensive detection without needing separate devices.

Built for modern homes, this detector uses clear voice alerts in addition to traditional alarms, so you know exactly what’s being detected. Three LED indicators provide quick status checks: green means normal operation, amber signals a fault or connection issue, and red lights indicate an active alarm. A Smart-Hush feature helps quiet nuisance sounds for about eight minutes, making everyday activity—like cooking or steaming showers—less disruptive while still maintaining safety measures.

Key features

• 2-in-1 detection for smoke and carbon monoxide in a single device
• Voice alerts identify the hazard type, complemented by an 85-decibel alarm
• 24/7 self-testing components continually monitor performance (not a substitute for manual tests)
• Whole-home interconnect with other Kidde alarms to trigger synchronized alerts
• Easy installation with a four-orientation mounting bracket
• 120V AC hardwired with 2-AA battery backup for reliable operation during outages
• UL Listed with a 10-year warranty on the alarm unit

Real-world use and maintenance

In daily life, this detector helps provide audible and spoken warnings when smoke or CO is present, with LED indicators offering at-a-glance status. The Smart-Hush button reduces interruptions during cooking or shower steam, while the interconnect feature extends awareness across multiple rooms and levels. For ongoing safety, perform a manual button test weekly and rely on the unit’s self-checks as a continuous safety routine.

• Install on every level of your home and near bedrooms for broader coverage
• Plan for four evenly spaced detectors in a typical multi-level layout
• Keep batteries fresh and test the unit regularly to maintain readiness

Note: Self-testing aids overall operation but does not replace manual tests. The alarm will guide you with voice prompts like “Fire!” or “Warning! Carbon Monoxide!” when needed, and the status LEDs provide immediate feedback on the unit’s health and performance.
