Smoke & Carbon Monoxide Detector


Our combo Smoke & Carbon Monoxide Detector Series utilizes the latest optical sensing chamber and advanced microprocessor to deliver optimum performance in detecting fire and the odorless, poisonous carbon monoxide.

SDCO-1ZBS series has a built-in speaker for voice prompts, allowing you and family members to know exactly why and where the alert is happening without any hassle to memorize unique alert sounds. It also has built-in temperature and humidity sensor to help monitor changes in the environment.

SDCO-1ZBS series has a loud 85dB at 3m siren for audio notification and warning. With auto-calibration, this combo detector automatically re-adjusts its detection threshold value according to changes in the environment. It also has self-diagnostics function to monitor device status and ensure optimal performance. Most importantly, it will continue to work even during a power outage.

Adopting ZigBee Pro HA 1.2 standard, SDCO-1ZBS series is compatible with other manufactures’ ZigBee systems and can be conveniently integrated into new or existing ZigBee systems to deliver quality detection. Fire and carbon monoxide can be a deadly duo, but  SDCO-1ZBS series makes it easier to protect yourself against both. When it comes to your safety, there is no room for compromise.
