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
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.
• 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
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.
• Built-in test switch
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.

Smoke Detector Specifications
Architectural/Engineering Specifications
Smoke detector shall be a System Sensor i3 Series model number_______, listed to Underwriters Laboratories UL 268 for Fire Protection Signaling Systems. The
detector shall be a photoelectric type (Model 2W-B, 4W-B) or a combination photoelectric/thermal (Model 2WT-B, 4WT-B) with thermal sensor rated at 1ꢀ5°F
(57.2°C). The detector shall include a mounting base for mounting to ꢀ½-inch and 4-inch octagonal, single gang, and 4-inch square back boxes with a plaster
ring, or direct 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 percent-per-foot nominal 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 (Model 2WT-B, 4WT-B) conditions. When
used in conjunction with the 2W-MOD2 module, 2-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.
