GEIST™ANALOG-TO-DIGITAL CONVERTER

Quick Installation Guide

Part Number:

A2D

Description

This analog-to-digital converter provides the ability to connect a dry contact, 4-20 mA or a 0-10 VDC sensor to an RJ12 sensor port.

The following are some types of analog sensors that can be utilized with the A2D converter:

• Door Position
• Power Failure
  • Water-Sensing Cable
• Flood Sensor
• Isolated Voltage
• Smoke Alarm
  • Industry Standard 0-10 VDC or 4-20 mA

NOTE: The A2D sensor can span a total cable distance up to 600 ft from the Geist environmental monitoring device.

Installation

1. Mount the plastic enclosure anywhere in the data center with screws, magnets, zip ties or Velcro tape.
2. Connect the analog and/or dry contact device to the A2D sensor by attaching the common wire to terminal C and the remaining wire to terminal 1.
3. Plug one end of the uplink cable into one of the RJ12 ports of the A2D and plug the other end into the sensor port (RJ12/ Q) of the Geist environmental monitoring device or rack PDU.

NOTE: Sensors can be daisy chained by plugging an uplink cable into the second RJ12 port of the A2D and the other end into another A2D's RJ12 port.

Once connected, the Geist environmental monitoring device automatically detects and identifies the sensor.
