System Sensor 2W-B 2-Wire Photoelectric i3 Series Smoke Detector, White

The i3 series of fire detectors is designed with simplicity, intelligence, and efficiency in mind. Offering an advanced solution for fire detection, the i3 line revolutionizes installation and maintenance processes. The innovative plug-in design streamlines the installation process, allowing installers to pre-wire bases, which are conveniently included with the heads. This design also accommodates a variety of mounting methods, including direct mounting with drywall anchors or back box mounting. Thanks to the large wire entry port and in-line terminals, there is ample room for organizing the wiring neatly inside the base, ensuring a clean and efficient setup.

The i3 detectors are engineered with intelligent features that minimize false alarms and simplify ongoing testing and maintenance. Drift compensation and smoothing algorithms are integrated into every i3 detector, ensuring accurate detection while preventing unnecessary alarms. In addition, the 2-wire i3 detectors can trigger a remote LED-indicated maintenance signal when connected to a 2W-MOD2 loop test or a panel equipped with the i3 protocol. The SENS-RDR wireless device offers real-time visibility into the sensitivity of each detector, with clear readings in terms of percent-per-foot obscuration. Furthermore, instant inspection is made possible with wide-angle red and green LED indicators, providing clear status updates such as normal standby, out-of-sensitivity, alarm, or freeze trouble. The 2-wire i3 detectors also support the EZ Walk loop test feature, which allows for quick verification of the initiating loop wiring with LED status indications on each detector.
