Features:
System Sensor i3 series smoke detectors represent significant advancement in conventional smoke detection. The i3 family is founded on three principles: installation ease, intelligence, and instant inspection.
? Plug-in detector line, mounting base included
? Large wire entry port ? In-line terminals with SEMS screws
? Mounts to octagonal and single-gang back boxes, 4-square back boxes, or direct to wall or ceiling
? Stop-Drop ?N Lock attachment to base
? Removable detector cover and chamber
? Built-in remote maintenance signaling
? Drift compensation and smoothing algorithms
? Simplified sensitivity measurement
? Wide-angle, dual-color LED indication
? Loop testing via EZ Walk feature
? Built-in test switch
