Agency Listings Photoelectric Smoke Detectors System Sensor’s i3™series smoke detectors representsignifcant advancement in conventional detection. The i3 amily is ounded on three principles: installation ease, intelligence, and instant i nspection. 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 Drit compensation and smoothing algorithms Simpliied sensitivity measurement Wide angle, dual color LED indication Loop testing via EZ Walk eature Built-in test switch • • • • • • • • • • • • Installation ease. The i3 line redenes 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 or neatly routing the wiring inside the base. The base accommodates a variety oback box mounting methods, as well as direct mounting with drywall anchors. T o complete the installation, i3 heads plug in to the base with a simple Stop-Drop ’N Lock™ action. Intelligence. i3 detectors ofer a number ointelligent eatures to simpliy testing and maintenance. Drit compensation and smoothing algorithms are standard with the i3 l ine to minimize nuisance alarms. Two-wir e 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 sensitivityoi3 detectors in terms opercent per-oot-obscur ation. Instant inspection. The i3 series provides wide-angle red and green LED indicators or instant inspection othe detector’s condition: normal standby, out-o-sensitivity, alarm, or reeze trouble. When connected to the 2W-MOD2 loop test/maintenance module or a panel with the i3 protocol, the EZ Walk loop test eature is available on two-wire i3 d etectors. This eature veries the initiating loop wiring by providing LED status indication at each detector. 209290-01-E 7272-1209:210 011446 S911

Smoke detector shall be a System Sensor i3 Series model number_______, listed to Underwriters Laboratories UL 268 or 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 15°F
(57.2°C). The detector shall include a mounting base or 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 o SEMS screws. The detector shall allow pre-wiring o
the base and the head shall be a plug-in type. The detector shall have a nominal sensitivity o 2.5 percent-per-oot nominal as measured in the UL smoke box.
The detector shall be capable o automatically adjusting its sensitivity by means o drit compensation and smoothing algorithms. The detector shall provide
dual color LED indication which blinks to indicate power up, normal standby, out o sensitivity, alarm, and reeze trouble (Model 2WT-B, 4WT-B) conditions. Whenused in conjunction with the 2W-MOD2 module, 2-wire models shall include a maintenance signal to indicate the need or maintenance at the alarm control
panel, and shall provide a loop testing capability to veriy the circuit without testing each detector individually.
