Air Quality Information System (AQIS)
WHAT DOES IT DO?
AQIS can monitor levels of many airborne contaminants that are considered risky or dangerous in occupied spaces. It will:
- Pinpoint the location where a sensor has detected a sustained and measureable contamination level.
- Qualifies the identity of a contaminant based on the substance the sensor is designed to measure.
- Provides real time measurement of the contaminants levels as well as increases and decreases in concentration.
- Uses wireless technology to deliver critical event information to any communications device approved by user.
THE FIRST SCREEN
On the HMI display is the AQIS Dashboard which has one or more Vertical gauges each calibrated to represent the highest level of monitored gas in PPM (Parts Per Million). The gauge is color coded to highlight the current contamination levels in a monitored space or zone.
THE SECOND SCREEN
On the HMI display is a diagram of the area where the Alert Status is being triggered. Sensor locations are identified along with the color code for gas concentration levels. There is an Alert Status information block that provides real time updates about the Alert and an Event Summary information block that provides real time updates about the event.
FIRST LEVEL (GREEN)
NO ACTIVE ALERTS OR ALARMS
All sensors indicate that there are no gas concentration levels above measured threshold level.
THE SECOND SCREEN ACTIVE ALERTS & ALARMS
Real time ALERTS are provided when threshold levels are reached. Updates are provided based on an increase in gas concentration as determined by either elapsed time or a rate of rise algorithm which measures a rise in gas concentration over a specific time element.
ALARMS are triggered when certain gas concentration levels are achieved that coincide with OSHA alarm protocols for human relocation to safer areas and Response Team actions.
THE THIRD SCREEN
EVENT SUMMARY SCREEN
At the end of any AQIS measured event, a third screen will be displayed on the HMI. This event summary presents all information, alerts and alarms experienced during an AQIS measured event. This screen can be printed or transmitted for use when preparing National Response Center report of a gas concentration event.
EVENT SUMMARY (Example)
|EVENT ADDRESS||1234 MAIN STREET, SOMEWHERE USA|
|EVENT LOCATION||AMMONIA COMPRESSOR ROOM - COMPRESSORS 3 ∓ 4|
EVENT SUMMARY SCREEN - CONT'D
At the end of any AQIS measured event, a third screen will be displayed on the HMI.
|EVENT END TIME||12:11:00|
|TOTAL ALERT STATUS DURATION||71 MINUTES|
|TOTAL ALARM STATUS DURATION||35 MINUTES|
|TOTAL EVENT DURATION||106 MINUTES|
|HIGHEST CONCENTRATION LEVEL||306 PPM|
