1.2 Configuration

The Model 2102 is available with or without a built in audible alarm at the controller:

Model 2102-00: Standard Controller.

Model 2102-01: Controller with audible alarm annunciator (common to both gas monitors) installed in the enclosure door.

The standard controller is provided with the relays configured for separate activation by their respective gas

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.

CABLE	GAUGE	CONDUCTORS
LENGTH
500 feet	22 AWG	4
1,000 feet	18 AWG	4
1,500 feet	16 AWG	4

Table 1 Sensor Cable Requirements

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.

monitors. (i.e.: Monitor #1 activates relay #1 and sensor #2 activates relay #2).

On request, the factory installs a jumper wire to re-configure the relays to activate on an “or” basis so that when either sensor alarms both relays energize. This jumper is indicates in the locator diagram and van be field installed by a technician.

Model 2102 connections as indicated in Table 2.

4	White	Alarm Signal

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:
