General
System Sensor’s i³™ 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
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 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 Lock™ action.
Intelligence. i³ Series detectors offer a number of intelligent
features to simplify testing and maintenance. Drift compensa-
tion and smoothing algorithms, to minimize nuisance alarms,
are standard in the i³ Series. When connected to the 2W-MOD
loop test/maintenance module, an SFP-2402/-2404 panel,
SFP-5UD/10UD, or RP-2001/2002 two-wire i³ detectors are
capable of generating a remote maintenance signal when they
need cleaning. This signal is indicated by LEDs located at the
module and at the panel. To read the sensitivity of i³ detectors,
the SENS-RDR is a wireless device that displays sensitivity in
terms of percent-per-foot obscuration.
Instant inspection. The i³ Series provides wide-angle red and
green LED indicators for instant inspection of detector condi-
tion. The LEDs indicate: normal standby, out-of-sensitivity,
alarm, or freeze trouble conditions. The “EZ Walk” loop test
feature is available on two-wire i³ Series detectors when con-
nected to the 2W-MOD loop test/maintenance module. The
“EZ Walk” feature verifies the initiating loop wiring by providing
LED status indication at each detector.
