DF-52521:B1 •F-505 i3 Series FlrelffeALarmS Photoelectric Smoke Detectors by Honeywell DevicesConventional Initiating General System Sensor's i3TM Series photoelectric and photoelectric/ thermal smoke detectors represent a significant advancement in conventional detection, incorporating three key features: installation ease, intelligence,and instant inspection. Installation ease. The i3 Series redefines installation ease with 1 its plug-in design.This allows an installer to pre-wire the bases included with the heads. The large wire-entry port and in-line terminals provide ample room for neatly routing the wiring 4W inside the base.The base accommodates a variety of backbox mounting methods, as well as direct mounting with drywall anchors.To complete the installation, i3 Series heads plug into the base with a simple Stop-Drop'N LockTM action. Intelligence. i3 Series detectors offer a number of intelligent features to simplify testing and maintenance.
