3.12.4.2.2. ALRM UM = CFM [L/s]
Default: 0
Optional Settings: 0 to 999999 (CFM [L/s])
3.12.4.2.3. ALRM UM = iWG [Pa]
Default: 0
Optional Settings: 0.00 to 5.00 (iWG) [0 to 1250 (Pa)]
3.12.5. Alarm Tolerance [TOL]
The airflow tolerance, as a percentage of the setpoint, used to activate the airflow alarm.
[Menu path: SETTINGS >↓ ALARM >↓ TOL]
Default: Greater of 15% or 20 FPM [0.10 m/s]
Optional Settings: Greater of 5% or 20 FPM [0.10 m/s] to 100% or 20 FPM [0.10 m/s]
20 FPM [0.10 m/s] is less than 0.0001 iWG [0.025 Pa] when a -B probe type is configured for
pressure and the setpoint is set to 0.
3.12.6. Alarm Delay [DELAY]
The delay, in minutes, that the alarm state must be “outside”, to activate the airflow alarm.
[Menu path: SETTINGS >↓ ALARM >↓ DELAY]
Default: 2min (minutes)
Optional Settings: 0min to 15min
3.12.7. Alarm on Zero Flow [ZERO OFF]
Disable the airflow alarm when the airflow output of the transmitter is set to 0%.
[Menu path: SETTINGS >↓ ALARM >↓ ZERO OFF]
Default: YES
Optional Settings: NO
Use the low limit cutoff (LLIMIT) to improve functionality of the airflow alarm in systems that have “off
or “unoccupied” modes.
3.12.8. Alarm Reset Method [RESET]
Automatically reset (clear) the alarm when the fault is inactive or require manual reset.
[Menu path: SETTINGS >↓ ALARM >↓ RESET]
Default: AUTO
Optional Settings: MANUAL
RESET = AUTO. The alarm is automatically reset when the alarm state returns to “normal” or the alarm is
manually reset.
RESET = MANUAL. The alarm must be manually reset by pressing the ESC button.
An active alarm can be reset manually by pressing the ESC pushbutton. The alarm state will return
to “normal”. If the airflow is outside of the specified setpoint and tolerance, the alarm state returns to
“outside” and the delay timer is reset.
