Smoke Detectors  
System Sensor’s i3series 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  
Lockaction.  
• 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.
