Notifier NFX-TDIFF-IV Heat Detector ROR

Notifier NFXI-TDIFF uses the same thermistor and microprocessor technology to provide an alarm when therate of rise in temperature exceeds 10°C/minute (typical) or if the temperature exceeds a threshold of 58°C(Response Class A1R). Notifier’s Opal protocol allows it to be software configured to be either a fixed 58°C, afixed 78°C unit or a 58°C with rate of rise device. For backwards compatibility and approval continuity, threeseparate versions continue to be available as separate part numbers
