Advanced Detection Technology for Reliable Fire Safety

The SIGA-HRD and SIGA-HFD are intelligent heat detectors designed for precise fire detection using temperature sensing. They offer both fixed temperature and rate-of-rise detection, ensuring early and accurate fire response in environments where smoke detection may not be ideal.
