TECHNICAL BULLETIN TB-3019 Dual-Wire Dual-Operator Programmable Monitor Made in the Installation, Operation and Maintenance United States of America Features and Components A B Figure 1. Desco 19665 Dual-Wire Dual-Operator Programmable Monitor C D Description FRONT VIEW The Desco Dual-Wire Dual-Operator Programmable Monitor monitors two operators and two ESD worksurfaces eliminating the need for periodic testing and record keeping of wrist straps. The Dual-Wire Dual-Operator Programmable Monitor uses low-voltage steady state DC continuous-loop technology to continuously monitor (versus pulsed or intermittent) dual-wire wrist strap functionality. Independent audio and visual alarm conditions make it easy to identify the status of the worksurfaces and operators. Two operator remotes with 10 foot cables are included for use at adjacent workstations. Each monitor is calibrated with accepted E F G H I J K L procedures and standards traceable to the National Institute of Standards and Technology (NIST) and includes a NIST BACK VIEW certificate.

Installing the Dual-Wire Dual-Operator 1. Determine the mounting location of the Dual-Wire Programmable Monitor Dual-Operator Monitor. The front panel should be visible to both operators. Operation 2. Determine the mounting locations of the operator 1. Monitoring of the operators will remain in the STANDBY remotes. Be sure to install the remotes at a distance condition until a wrist cord is plugged into the operator that enables the 10 foot leads to reach the back of the remote. STANDBY mode is indicated by a blinking monitor. yellow operator LED. 3. Install tinned wire ends of the mat cords to their 2.
