Option Available Configurations
Sensitivity • Detects 1 square foot gasoline fire at 210 feet (very high
sensitivity) or 100 feet (medium sensitivity).
Optical Integrity (o
i
)
*
Automatic o
i
- Automatically checks internal circuitry and
cleanliness of viewing windows to ensure proper operation.
If a fault condition exists, the amber Fault LED lights.
• Manual o
i
- Cleanliness of viewing windows test can be
manually initiated by closing an external switch that is elec-
trically connected between the o
i
lead and circuit ground.
Warning: Successful Manual o
i
test results in fire alarm
relay activation and red Alarm LED lights.
• Internal circuitry is automatically tested independent of the
Manual o
i
test
Fire Relay Latching/Non-Latching • Latching - Relay remains in “Fire” condition after fire has
been detected until X3300 power is cycled.
*
Non-latching - Relay remains in “Fire” condition only as long
as a fire is being detected.
Normally Energized/De-Energized • Normally Energized - Fire relay is energized in non-alarm
(no fire) condition.
*
Normally De-Energized - Fire relay is de-energized in non-
alarm (no fire) condition.
Contacts Normally Open/Closed
*
Normally Open - Fire relay contacts are open in non-alarm
(no fire) condition.
• Normally Closed - Fire relay contacts are closed in non-
alarm (no fire) condition.
Fault Relay Latching/Non-Latching • Latching - Relay remains in “Fault” condition after fault has
been detected until X3300 power is cycled.
*
Non-latching - Relay remains in “Fault” condition only as
long as a fault is being detected.
Normally Energized
*
Normally Energized - Fault relay is energized with no fault
present.
Contacts Normally Open/Closed
*
Normally Open - Fault relay contacts are open when fault is
present.
• Normally Closed - Fault relay contacts are closed when
fault is present.
4 to 20 mA Output • Current output level indicates detector status condition.
