Colorlight SSR-SMOG Smoke Transducer
The Colorlight SSR-SMOG is a ceiling-mounted smoke sensor with RS485 communication and a built-in sound-and-light alarm. It uses MODBUS RTU for remote data queries and settings through compatible serial communication software.
Smoke monitoring and alarm indication
The sensor is described in the specification as a qualitative smoke-monitoring device. Its measuring range is 0–2000 ppm; this range is separate from the listed maximum permissible error of ±7%. Indicators on the housing show alarm, power and communication status.
The unit supports ceiling mounting and has a standard 5 m wire. The probe can be replaced. For integration, match the MODBUS RTU communication settings to the monitoring system; the listed baud rate is 9600.
