GUARDIAN™ ASSIST Ultraviolet Monitor Extension

Overview

The GUARDIAN™ ASSIST is designed to remotely indicate the intensity level displayed on the GUARDIAN™ Ultraviolet Monitor.

• The GUARDIAN™ ASSIST converts a 4–20 mA signal from the GUARDIAN™ Ultraviolet Monitor to an intensity level displayed on the monitor face. A 4 mA signal would read 0 and a 20 mA signal would read 120.
• The GUARDIAN™ ASSIST intensity reading will be the same as the GUARDIAN™ Ultraviolet Monitor +/- 2%.

When the GUARDIAN™ Ultraviolet Monitor detects a germicidal ultraviolet energy level which is acceptable:

• The GUARDIAN™ ASSIST will light a green LED on the front of the instrument panel with the heading “NORMAL.”
• The Display should read between 30 and 120.

When the GUARDIAN™ Ultraviolet Monitor detects a germicidal ultraviolet energy level which is unacceptable:

• The GUARDIAN™ ASSIST will light a red LED on the front panel with the heading “LOW.”
• The display should have a reading below 30.

Internal Audio Alarm:

• When the GUARDIAN™ Ultraviolet Monitor detects a germicidal energy level is unacceptable, an audio alarm will sound on the GUARDIAN™ ASSIST. The alarm can be disabled by an ON/OFF switch on the front of the unit.
