Photoelectric Smoke Detectors

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 compensa­tion 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 condi­tion. 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 con­nected 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.

Architectural/Engineering
Specifications

Smoke detector shall be a System Sensor i³ Series model
number ________, Listed to Underwriters Laboratories UL
268 Fire Protection Signaling Systems. The detector shall be a
photoelectric type (models 2W-B, 4W-B) or a combination pho­toelectric/thermal (models 2WT-B, 4WT-B) with thermal sensor
rated at 135°F (57.2°C). The detector shall include a mounting
base for mounting to 3.5" (88.9 mm) and 4" (101.6 mm) octag­onal, single-gang, and 4" (101.6 mm) square backboxes with a
plaster ring, or directly mount to the ceiling using drywall
anchors. Wiring connections shall be made by means of
SEMS screws. The detector shall allow pre-wiring of the base
and the head shall be a plug-in type. The detector shall have a
nominal sensitivity of 2.5%/foot (0.762%/meter) as measured
in the UL smoke box. The detector shall be capable of auto­matically adjusting its sensitivity by means of drift compensa­tion and smoothing algorithms. The detector shall provide
dual-color LED indication which blinks to indicate power-up,
normal standby, out-of-sensitivity, alarm, and freeze trouble
(models 2WT-B, 4WT-B) conditions. When used in conjunction
with the 2W-MOD module, two-wire models shall include a
maintenance signal to indicate the need for maintenance at
the alarm control panel, and shall provide a loop testing capa­bility to verify the circuit without testing each detector individu­ally.
