Logical Grouping Options . . . . . . . . . . . . . . . . . . . . . . . . Alarm Triggers on any user-selected logical grouping of up to 8 test
conditions (up to 7 if using the Minus or Difference Test Condition/
Check Type): OR (any test conditions can be true), AND (all test
conditions must be true), XOR (only one test condition can be true),
DONE (only on test condition used)
Alarm Logging . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . The log will consist of which output became active, which parameters
caused the alarm to become active (useful for the AND type alarm)
along with the date and time that the alarm became active. This log is
cleared whenever any of the output alarms are cleared. Can be
activated or deactivated by the user.
Output Contact Closure Functions
Duration . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to 255 minutes (user selectable). Determines how long the alarm
output should stay active once it is triggered. Default = 10 minutes
Reactivation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to 255 minutes (user selectable). Determines how long to leave the
alarm output deactivated once it is deactivated. Default = 0.
Pulse Width . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to 9999 milliseconds (user selectable). Default = 2000 milliseconds
(2 seconds).
Activation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Continuous or Pulse (1-time) (user selectable). Determines whether
a pulse for alarm activation is continuous throughout the activation
time or a one time pulse. Pulsed relay oriented devices will require the
one-time pulse. Default = Continuous
Circuit Behavior . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Normally Open or Normally Closed (user-selectable). Determines
whether the circuit stays open or closed when no alarms are active.
The opposite behavior occurs for an active alarm condition. Normally
closed is the most typical operation for Irrigation controller use.
Default = Normally Closed.
Test Mode Function. . . . . . . . . . . . . . . . . . . . . . . . . . . . . Available. Continuous, Open, or Closed circuit (user-selectable).
WeatherLink for Emergency Response Teams with Streaming Data
Logger (# 6550)
The Streaming Data Logger is designed for use with the free CAMEO
®
or ALOHA
®
software. It provides the real-
time weather data needed to map the "footprint" of a hazardous plume, predict its dispersion, and help make critical
public safety decisions. Please note that this product is specifically designed to work with CAMEO
®
and ALOHA
®
software programs and will not work with other such programs of this type. For further and more detailed information
on this product, please visit the following website:

Note: CAMEO, or Computer-Aided Management of Emergency Operations, is a suite of three integrated software applications, including ALOHA
®
Areal
Locations of Hazardous Atmospheres.
Hardware Installation and Requirements
In addition to the WeatherLink requirements, the streaming data capability has the following additional hardware
requirements:
• Computer running 98, 98SE, ME, 2000, XP, or Vista with Microsoft .NET 2.0 framework. Requires at least
1 MB of RAM and 2.5 MB of hard disk space.
Functional Specifications
Time Out Period: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . The streaming data logger utilizes a time-out period for ceasing
streaming whenever software attempts to communicate to the logger.
Once communications to WeatherLink are initiated and successful,
the streaming data logger will be unable to communicate with the
Streaming Data Utility until the Time Out Period expires.
Range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 to 255 seconds (user selectable)
Default Value. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5
Station ID # . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ALOHA
®
uses a station ID number in the streaming data transmission.
Although a station ID number is included in each data transmission,
ALOHA
®
does not use this value.
