Common Use Cases
There are three typical use cases for the Alternate Room Pressure Monitor Solution:
● Basic operation
● Silent operation
● Synchronized operation
Basic Operation – Alarm text and red light activate immediately when the door is opened and pressurization is
lost. Audible alarm is silent unless the door stays open longer than a configured delay time.
Silent Operation – Alarm text and red light activate only if the door stays open beyond a configured delay time.
Audible alarm stays silent.
Synchronized Operation – Alarm indications (text, light, and buzzer) occur together if the door stays open
beyond a configured delay time.
Function
Key
1 Room differential pressure input (DiffPR) is monitored by the Room differential pressure alarm Event Enrollment object
(DiffPRAlm).
2 DiffPRAlm monitors DiffPR and affects the lights and the display text. DiffPRAlm must be configured for High limit, or Low limit, or
both.
Possible states for the LED:
● Green = Normal condition
● Red = Fault condition
● Flashing red = Hi/Lo alarm
3 AlmInd monitors DiffPRAlm and affects the buzzer.
If AlmInd is Fault or Off-Normal, the buzzer will sound until silenced.
