Alarm Delay
To account for hysteresis and prevent nuisance alarms or premature recoveries, users can define
the amount of time that the Rooster
TM
has to achieve continuous safe velocity readings before
the alarm state clears and continuous unsafe velocity readings before an alarm is triggered. This
is called Alarm Delay.
Alarm is cleared after 1 second if velocity readings are above the alarm clear threshold.
Alarm is triggered after 1 second if velocity readings are below the alarm trip threshold.
This is the default setting.
Alarm is cleared after 2 seconds if velocity readings are above the alarm clear threshold.
Alarm is triggered after 2 seconds if velocity readings are below the alarm trip threshold.
Alarm is cleared after 5 seconds if velocity readings are above the alarm clear threshold.
Alarm is triggered after 5 seconds if velocity readings are below the alarm trip threshold.
Alarm is cleared after 10 seconds if velocity readings are above the alarm clear threshold.
Alarm is triggered after 10 seconds if velocity readings are below the alarm trip
threshold.
Startup Delay
The startup delay prevents an alarm from triggering until the workstation and ventilation
systems have fully powered up and are operational. Refer to chart on next page for further
definitions.
Alarm is paused for 30 seconds on power up.
Alarm is paused for 1 minute on power up.
Alarm is paused for 2 minutes on power up.
Alarm is paused for 5 minutes on power up.
Latch Alarm
Alarm latching is a useful feature to indicate that an alarm state was triggered even if the device
is no longer in an active alarm state. This could occur, for example, when a user has stepped
away from the workstation. When latching is activated “On”, a yellow banner will display
beneath the velocity and temperature readings on the home screen to indicate that a low
airflow event has occurred. When latching is set to “Password”, an EH&S passcode must be
