Automatic Oi
The UVIR EQ2200 includes the Automatic Optical Integrity (Oi) feature — a performance test that is automatically
performed to verify complete detector operation capabilities.
No testing with an external test lamp is required. The detector automatically performs the same test that a
maintenance person with a test lamp would perform —once every minute, 60 times per hour. However, a
successful automatic Oi test does not produce an alarm condition. While the default Oi test frequency is once
a minute, it can be changed to once an hour, every two hours, or once every four hours. The default mode is
Automatic. Manual Oi tests can be initiated from the point display in the S 3 software.
Time Delay
An input time delay can be programmed by entering a value from 1 to 7 seconds in the provided field. This will
delay sending the fire alarm message to the EQP controller until the fire alarm has been generated uninterrupted
for the specified time. This programmable delay can be used to filter out spurious events.
PV Deadband
A field is provided to enter the desired PV (Process Variable) Deadband. Normally all values are transmitted to
the controller every five seconds; If the PV changes more than the entered percentage before the five second
report time arrives, an immediate message is sent with the current values.
