Smoke & Carbon Monoxide Detector

SDCO-1 Series

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.

The SDCO-1 Series has a loud 85dB 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. In addition, the SDCO-1 Series features several optional functions, including rate-of-rise heat detection and interconnection function. Most importantly, it will continue to work even during a power outage.

Fire and carbon monoxide can be a deadly duo, but Climax’s SDCO-1 Series offers protection from two deadly threats in one unit. Not only does it save space, but also allows users to change and test batteries in one device rather than two. Furthermore, the SDCO-1 Series adopts Climax’s industry-leading RF technologies to deliver super speed signal transmission and extensive communication range.
