System Sensor 2WTA-B i3 Series Smoke Detector

**CALL FOR AVAILABILITY**

The 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. When the i3 is connected to the following, the 2-wire, i3 detectors are capable of generating a remote maintenance signal.

• 2W-MOD Loop Test/Maintenance Module
• i3 ready panel (MS-2 and MS-4) equipped with the i3 protocol

The remote maintenance signal indicates when the i3 required cleaning and it is indicated via an LED located at the module and/or the panel. To read the sensitivity of i3 detectors, the SENS-RDR is a wireless device that displays the sensitivity in terms of percent per foot obscuration.

The i3 Series provide wide angle, red and green LED indicators that allow you to instantly inspect the following detector conditions: normal standby / Alarm / Out-of-sensitivity / Freeze trouble condition.

When the i3 is connected to the 2W-MOD Loop Test/Maintenance Module or an i3 ready panel (i.e., MS-2 and MS-4) 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 the LED status indication at each detector.
