2W-MOD2 2-Wire Loop Test/ Maintenance Module The 2W-MOD2 2-wire loop test/maintenance module maximizes the benefits of i3™ Series smoke detectors by enabling detector remote maintenance signaling and EZ Walk loop testing capabilities. Features i3 •Allows all 2-wire detectors to be used on any listed alarm control panel capable of utilizing this module. •Interprets the i3 remote maintenance signal •Provides visual indication and an output relay when a detector on the loop requires cleaning •Initiates the EZ Walk loop test •Provides Style D wiring on IDC loops •Has green, red, and yellow LEDs that indicate: – Loop communication status – Maintenance alert – Freeze trouble – Alarm – EZ Walk test enabled – Wiring fault CS308 3015195 7300-1653:166 Intelligence. The 2W-MOD2 allows communication to 2-wire i3 detectors with any listed fire alarm control panel capable of utilizing this module. When these i3 detectors initiate a remote maintenance signal for required cleaning, both the 2W-MOD2 and the panel can provide a visual indication of the signal. The 2W-MOD2 module also features the EZ Walk loop test for 2-wire i3 detectors. With just the press of a button, this function verifies the entire initiating loop wiring. Instant inspection. The 2W-MOD2 2-wire loop test/maintenance module's green, red, and yellow LEDs provide status indication for the loop. These LEDs indicate loop communication status, maintenance alert, alarm, freeze trouble, EZ Walk test enabled, and wiring fault. Agency Listings S3705 Installation ease. The 2W-MOD2 2-wire loop test/maintenance module mounts to a 4-inch square back box for quick and easy installation. Terminal blocks with durable SEMS screws assure a reliable connection. 4-03-E 2W-MOD2 Specifications Architectural/Engineering Specifications Loop test/maintenance module shall be System Sensor i3™ Series model number 2W-MOD2, listed to Underwriters Laboratories UL 864 for Control Units for Fire Protection Signaling Systems.
