2.1 Installation
Determine suitable locations for the Model 2102 and the fixed gas monitors. Mount the panel at eye level using the mounting flanges on the top and bottom of the enclosure. Install ¾” electrical conduit from the right hand tub to the monitor locations. For installation convenience the wiring for both sensors can be run in the same conduit necessary. Pull four conductors for each monitor. See Table 1 for wire gauge requirements. The normal SMC color coding is green, red, black, white.

Connect these wires to the terminal strip in the gas monitor and to the corresponding terminal in the gas monitor and to the corresponding terminal in the Central Panel. The four terminal barrier strips in the Model 2102 are marked “SENSOR 1” and “SENSOR 2” to correspond with the lights for Channels “1” and “2” on the front panel.

Table 2 Model 2102 Terminations
Connect to the appropriate terminal strip pin # (as marked) in the fixed gas monitor.
CAUTION: The terminal strip positions in the gas monitor are marked with the correct numbers as they are not in logical sequence, insure that the wires are installed in the correspondingly numbered positions, not in logical sequence.
Connect ¾” conduit to the left hub of the enclosure to run 120 VAC power wiring to connect externally operated alarms, lights or fans to the relay terminal strips as required.
The relay terminal strips are identified as “J2” corresponding to Cannel 1 and “J3” corresponding to Channel 2. The connections can be used as follows:
