Installation ease, intelligence, and instant inspection are the guiding principles of the System Sensor i 3 Series photoelectric smoke detectors. The i3 Series is a complete line – standard, sounder, auxiliary Form C relay, and isolated thermal models – featuring plug-in bases, removable covers, remote maintenance signaling, drift compensation and smoothing algorithms, green and red LEDs, and simplified sensitivity measurement.
