System Sensor 4W-B i3 Series 4-wire, Photoelectric i3 Smoke Detector
Installation Ease. Intelligence. Instant Inspection. These are the guiding principles of System Sensor?s i3 Series photoelectric smoke detectors. Designed to take conventional smoke detectors to a new level, these principles translate directly into significantly lower installation, testing, and maintenance costs.
Installation:
Ease Because of its plug-in design, installing i3 is quick and simple. Efficient wire management and pre-wiring capabilities slash installation time. To complete the installation, simply Stop-Drop ?N Lock? the head onto the base.
Intelligence:
The i3 Series offers intelligence through drift compensation and smoothing algorithms to reduce unnecessary maintenance calls. And when a 2-wire i3 detector needs cleaning, its remote maintenance signal lets you know.
Instant Inspection:
Green and red LEDs make status indication more intuitive on the i3 detector. And with the i3 reader, detector sensitivity measurement is precise and complete within seconds. Both features reduce inspection time to an instant. Simply put, the i3 Series? principles translate into lower installation, testing, and maintenance costs.
