System Sensor 2WTR-B Photoelectric i3 Series Smoke Detector with Thermal Sensor & Form C Relay

Installation Ease. Intelligence. Instant Inspection. These are the guiding principles of System Sensor’s i3 Series photoelectric smoke detectors. Designed to take conventional smoke detectors to a new level, these principles translate directly into significantly lower installation, testing, and maintenance costs.

Installation Ease
Because of its plug-in design, installing i3 is quick and simple. Efficient wire management and pre-wiring capabilities slash installation time. To complete the installation, simply Stop-Drop ’N Lock™ the head onto the base.

Intelligence
The i3 Series offers intelligence through drift compensation and smoothing algorithms to reduce unnecessary maintenance calls. And when a 2-wire i3 detector needs cleaning, its remote maintenance signal lets you know.

Instant Inspection
Green and red LEDs make status indication more intuitive on the i3 detector. And with the i3 reader, detector sensitivity measurement is precise and complete within seconds. Both features reduce inspection time to an instant.

Simply put, the i3 Series’ principles translate into lower installation, testing, and maintenance costs.

Features and Benefits
The i3 Series now features a complete line of smoke detectors. Standard, Sounder, Auxiliary Form C Relay, and Isolated Thermal – the choice is yours.

Standard
Most applications call for a standard detector. Whether the installation is an office building, retail establishment, hotel, or residence, the i3 Series installs easily, reduces nuisance calls, and dramatically reduces inspection and scheduled maintenance costs.

Sounder
Should the application require an audible output, the i3 Series now offers two- and four-wire sounder models. Ideal for residential applications, these units generate an 85 dBA temporal 3 tone and can easily be synchronized with the i3 reversing relay/synchronization module.

Auxiliary Form C Relay
When controlling auxiliary functions such as elevator recall or door closure, the i3 Series offers both two- and four-wire Form C relay models, available either with or without an integral sounder.

Isolated Thermal
To differentiate between a local and a general alarm, the i3 line offers an isolated thermal model. Ideal for dormitories, retirement facilities, and lofts, this four-wire model initiates a local alarm when smoke is detected and a general alarm when the thermal sensor is activated.

System Sensor i3 series smoke detectors represent significant advancement in conventional smoke detection. The i3 family is founded on three principles: installation ease, intelligence, and instant inspection.
