Version 6.0
Oi Mode
The UVIR X5200 includes the Automatic Optical Integrity (Oi) feature — a performance test that is automatically
performed to verify complete detector operation capabilities.
Combined Settings
The bottom portion of the dialog box contains settings for the alarm latching, Optical Integrity (Oi), input time
delay and PV deadband adjustments that apply to the whole detector as opposed to a specific sensor.
Alarm Latching Mode
The red LED on the face of the detector comes on when in alarm and can be configured to be either latching or
non-latching. If latching is selected, following a fire detection, the LED will stay on until the detector is reset from
the point display for the detector in the S 3 software. The default is non-latching.
Time Delay
An input time delay can be programmed by entering a value from 1 to 15 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.
