Photoelectric Smoke Detectors

Conventional Initiating Devices

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.
