System Sensor i3 Series Frequently Asked Questions And Answers

Frequently Asked Questions and Answers
Q. Why is the product called the i
3 ™
A. The i series represents a breakthrough in detection solutions, based upon three "I" principles: Installation ease,
Intelligence, and Instant Inspection. Installation ease is the result of the plug-in design, featuring the Stop-Drop 'N
Lock attachment, efficient wire management, and in-line terminals, all intended to reduce installation time.
™
Intelligence refers to intelligent features provided such as a remote maintenance signal, drift compensation, and
smoothing algorithms. These features minimize the likelihood of nuisance alarms. Instant inspection refers to the
3
way in which the i detectors' sensitivity can be measured, as well as the red and green LED's that readily indicate
the status of the smoke detector.
Q. What models are included in the i
3
A. The i series now offers a full-line of detectors and accessories to address a broader range of applications. They
include:
Detector Type
Two-wire standard
Two-wire standard with 135° F thermal
Two-wire sounder with 135° F thermal
Two-wire Form C relay with 135° F thermal
Four-wire standard
Four-wire standard with 135° F thermal
Four-wire sounder with 135° F thermal
Four-wire Form C relay with 135° F thermal
Four-wire sounder, with Form C relay, 135° F thermal
Four-wire isolated thermal, with sounder, Form C relay
Accessories
Loop test/maintenance module
Reversing relay/synchronization module
Sensitivity reader
Removal/replacement tool
Retrofit adapter bracket
Q. How does the new isolated thermal model operate?
3
A. The i isolated thermal detector, model number 4WITAR-B, operates similarly to the 2112/24AITR. Specifically,
when the detector's photoelectric chamber detects smoke, only a local alarm indication is provided. Conversely,
should the detector's thermal sensor be activated, a general alarm condition will result.
Q. Is the 2W-MOD no longer available?
A. The 2W-MOD was replaced by the 2W-MOD2. This new accessory accommodates all 2-wire standard, sounder,
3
and relay i detectors.
Q. Can the original 2W-MOD be used with the new i
A. No. The 2W-MOD cannot be used with the new i
3
can be used on all i detectors, both old and new.
3
Q. Can the other i accessories be used with the new i
3
A. All other i accessories may be used with the new i
reader, removal/replacement tool, and the retrofit adapter bracket.
Q. What is the RRS-MOD and what are its functions?
A. The RRS-MOD serves two purposes. First, it activates all i
reversing the polarity of the power circuit. This allows the capability of installing multiple i
loop. Second, the RRS-MOD synchronizes the output of all i
signal.
