Smoke Detectors
System Sensor’s i3^™ series smoke detectors represent
significant advancement in conventional detection.
The i3 family is founded on three principles: installation
ease, intelligence, and instant inspection.
Features
• Plug-in detector line, mounting base included
• Large wire entry port
• In-line terminals with SEMS screws
• Mounts to octagonal and single-gang backboxes, 4-square
backboxes, or direct to 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

Installation ease. The i3 line redefines installation ease with 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 inside the base.
The base accommodates a variety of back box mounting methods,
as well as direct mounting with drywall anchors. To complete the
installation, i3 heads plug in to the base with a simple Stop-Drop ’N
Lock^™ action.
Intelligence. i3 detectors offer a number of intelligent features
to simplify testing and maintenance. Drift compensation and
smoothing algorithms are standard with the i3 line to minimize
nuisance alarms. Two-wire i3 detectors needing cleaning can
generate a remote maintenance signal, when connected to the
2W-MOD2 loop test/maintenance module, or to a panel equipped
with the i3 protocol. This signal is indicated by LEDs located at the
module and the panel. The SENS-RDR, a wireless device, displays the
sensitivityof i3 detectors in terms of percent per-foot-obscuration.
Instant inspection. The i3 series provides wide-angle red and
green LED indicators for instant inspection of the detector’s
condition: normal standby, out-of-sensitivity, alarm, or freeze trouble.
When connected to the 2W-MOD2 loop test/maintenance module
or a panel with the i3 protocol, the EZ Walk loop test feature is
available on two-wire i3 detectors. This feature verifies the initiating
loop wiring by providing LED status indication at each detector.
