System Sensor 2WTA-B is a 2-wire photoelectric i3 smoke detector with 135º Thermal Sensor and Sounder

Take Smoke Detection to a New Level

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

Installation ease. The i3 line redefines installation ease with its plug-in design. This allows an installer to pre-wire bases (included
with 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 into the base with a simple Stop-Drop ’N Lock™ action.

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. 2-wire i3 detectors can generate a remote LED- indicated maintenance signal when connected to the 2W-MOD2 loop test/maintenance module or a panel equipped with the i3 protocol. The SENS-RDR, a wireles devise, displacys the sensitivity of i3 dectors in terms of percent-per foot obscuration

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 2-wire i3 detectors. This feature verifies the initiating loop wiring by providing LED status indication at each detector

Manufacturer Part Number	2WTAB
Features	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. Features • Plug-in detector line, mounting base included • Large wire entry port • In-line terminals with SEMS screws • Mounts to octagonal and single-gang back boxes, 4-square back boxes, 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 • Built-in test switch

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.
