pERIODIC ChECkOUT pROCEDURE
A checkout of the system using the Mag
oi or Man oi
feature should be performed on a regularly scheduled
basis to ensure that the system is operating properly. To
test the system, perform the “Manual oi Test,” “Count
Test Mode” or “Fire Alarm Test” as described in the
“Startup Procedure” section of this manual.
CLOCk BaTTERy
The real time clock has a backup battery that will operate
the clock with no external power. Return the device to
the factory for battery replacement if needed.
NOTE
If the backup battery is depleted, there is no effect
on the operation of the flame detector, but the time
stamping of the data log may be affected.
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
• Pulse output for compatibility with controller based
systems
• Microprocessor controlled heated optics for
increased resistance to moisture and ice
• Automatic, manual or magnetic oi testing
• Easily replaceable oi plate
• Fire and fault relays
• Multiple sensitivity levels
• A tri-color LED on the detector faceplate indicates
normal condition and notifies personnel of fire
alarm or fault conditions
• Operates under adverse weather conditions and in
dirty environments.
• Mounting arm allows easy sighting
• Integral wiring compartment for ease of installation
• Explosion-proof/flame-proof detector housing.
Meets FM, CSA, ATEX Directive and CE certification
requirements
• Class A wiring per NFPA-72 (Pulse output version is
equivalent to class A when detectors are installed in
a redundant configuration)
• 5 year warranty
• RFI and EMC Directive compliant
SPECIfICaTIONS
OPERaTING VOLTaGE—
24 Vdc nominal (18 Vdc minimum, 30 Vdc maximum).
Maximum ripple is 2 volts peak-to-peak.
For CSA compliance, the power source must
utilize a SELV (Safety Extra Low Voltage) or Class
2 style power supply.
POWER CONSUmPTION—
Without heater: 4 watts at 24 Vdc nominal;
4.6 watts at 24 Vdc in alarm.
4.5 watts at 30 Vdc nominal;
5.9 watts at 30 Vdc in alarm.
Heater only: 8 watts maximum.
Total Power: 17 watts at 30 Vdc with EOL resistor installed
and heater on maximum.
EOL resistor must be ceramic, wirewound type, rated
5 watts minimum, with actual power dissipation not to
exceed 2.5 watts.
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 has redundant terminals and
normally open / normally closed contacts, normally
de-energized operation, and latching or non-latching
operation.
Fault relay, Form A, 5 amperes at 30 Vdc:
The Fault relay has redundant terminals and normally
open contacts, normally energized operation, and
latching or non-latching operation.
TEmPERaTURE RaNGE—
Operating: –40°F to +167°F (–40°C to +75°C).
Storage: –67°F to +185°F (–55°C to +85°C).
Hazardous location ratings from –55°C to +125°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 X3301 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 on “very high” setting.
Refer to Appendix A for FM Approved cone of vision data.
RESPONSE TImE—
Typical response times are under 10 seconds.
See Appendix A for actual response times.
