Technical Specifications

The i3™ Series smoke detectors with sounder and/or relay represent a significant technological advancement in conventional detection, featuring enhancements for simple installation, instant inspection, and intelligence for false alarm rejection.

All i3 series detectors are equipped with algorithms for automatic drift compensation and mathematical curve adjustment. These algorithms minimize the incidence of false alarms caused by short-term effects, such as electromagnetic induction and/or radio frequency interference, and long-term effects like dust accumulation. When 2-wire i3 detectors are connected to the 2WMOD2 loop maintenance and test module or to a panel compatible with the i3 protocol (i3 Ready™), they will generate a remote maintenance signal when a detector enters a cleaning condition and/or a freeze fault condition when the ambient temperature surrounding the detector drops below 5°C. To measure the sensitivity level of any i3 detector, the SENSRDR inspection tool is used, which allows the numerical sensitivity value, expressed as a percentage of obscuration per foot, to be viewed in a few seconds.
