Det-Tronics X3300EXE Protect-IR Multispectrum IR Flame Detector - Manual (Page 13)

FEATURES
• Long detection range to carbonaceous fires.
• Unequaled false alarm rejection.
• Responds to a fire in the presence of modulated
blackbody radiation (i.e. heaters, ovens, turbines)
without false alarm.
• Heated optics for increased resistance to moisture
and ice.
• Automatic and manual optical integrity ( oi) testing.
• Easily replaceable oi plate.
• Fire and fault relays standard.
• Tricolor LED indicates normal operation, fire and fault
conditions.
• Factory available fire and fault relay operation:
latching/non-latching, energized/de-energized (fire
relay only), normally open/normally closed.
• 4 to 20 mA isolated output.
• Multiple mounting options include mounting directly
onto most junction boxes using a simple adapter, or
the use of a swivel union or swivel mount available
from Det-Tronics.
• Operates under adverse weather conditions and in
dirty environments.
• ‘EEx d e’ flame-proof/increased safety detector
housing. Meets CENELEC and DNV certification
requirements.
• Class A wiring per NFPA-72.
• Meets NFPA-33 response requirement for under 0.5
second (available when option selected).
• 5 year warranty.
SPECIFICATIONS
OPERATING VOLTAGE—
24 volts dc nominal (18 vdc minimum, 32 vdc
maximum).
POWER CONSUMPTION—
7.5 watts at 24 volts dc nominal; 9.0 watts at 32 volts dc
maximum.
POWER UP TIME—
Fault indication clears after 0.5 second; device is ready
to indicate an alarm condition after 30 seconds.
OUTPUT RELAYS—
Fire Alarm relay, Form C, 5 amperes at 30 vdc:
The Fire Alarm relay is factory configurable for
normally open or normally closed contacts, normally
energized or normally de-energized operation, and
latching or non-latching operation.
Fault relay, Form C, 5 amperes at 30 vdc:
The Fault relay is factory configurable for normally
open or normally closed contacts, normally
energized operation, and latching or non-latching
operation.
CURRENT OUTPUT (Not available with relays)—
4 to 20 milliampere dc current, with a maximum loop
resistance of 500 ohms from 18 to 19.9 volts dc and 600
ohms from 20 to 32 volts dc.
TEMPERATURE RANGE—
Operating: –40°F to +158°F (–40°C to +70°C).
Storage: –67°F to +185°F (–55°C to +85°C).
HUMIDITY RANGE—
0 to 95% relative humidity, can withstand 100%
condensing humidity for short periods of time.
CONE OF VISION—
The detector has a 90° cone of vision (horizontal) with
the highest sensitivity lying along the central axis.
Unlike conventional detectors, the X3300 provides full
coverage at a minimum of 70% of the maximum
detection distance.
Perfect cone of vision for methane fire detection — 100
feet on and off axis. See Figures 9A to 9K.
RESPONSE TIME—
Typical response times are under 10 seconds. Models
are available that can respond to automotive paint gun
fires in under 0.5 seconds. See Appendix A for actual
response times.
ENCLOSURE MATERIAL—
Aluminum (red-painted) or 316 stainless steel.
DIMENSIONS—
See Figure 10.
WIRING—
14 AWG (1.5 mm2) to 22 AWG (0.3 mm2) shielded
cable is recommended.
Important: 18 vdc minimum must be available at the
detector.
THREAD SIZE—
Cable gland entries: M25.
