GENERal aPPlICaTION
INfORmaTION
RESpONSE ChaRaCTERISTICS
Response is dependent on the detector’s sensitivity
setting, distance, type of fuel, temperature of the fuel,
and time required for the fire to come to equilibrium. As
with all fire tests, results must be interpreted according
to an individual application. See Appendix A for fire test
results.
See Appendix A for third-party approved fire test results.
Additional fire test results are available from Det-Tronics.
IMpORTaNT appLICaTION CONSIDERaTIONS
In applying any type of sensing device as a fire detector,
it is important to know of any conditions that can prevent
the device from responding to fire, and also to know
what other sources besides fire can cause the device to
respond.
Welding
Arc welding should not be performed within 40 feet
(12.2 m) of the detector configured to very high
sensitivity, within 10 feet (3.0 m) at medium sensitivity,
within 5 feet (1.5 m) at T-Low sensitivity, or within 5 feet
(1.5 m) at Low sensitivity. It is recommended that
the system be bypassed during welding operations
in situations where the possibility of a false alarm
cannot be tolerated. Gas welding mandates system
bypass, since the gas torch is an actual fire. Arc welding
rods can contain organic binder materials in the flux that
burn during the welding operation and are detectable by
the X3301. Welding rods with clay binders do not burn
and will not be detected by the X3301. However, system
bypass is always recommended, since the material being
welded may be contaminated with organic substances
(paint, oil, etc.) that will burn and possibly cause the
X3301 to alarm.
artificial Lighting
The X3301 should not be located within 3 feet (0.9 m)
of artificial lights. Excess heating of the detector could
occur due to heat radiating from the lights.
EMI/RFI Interference
The X3301 is resistant to interference by EMI and RFI, and
is EMC Directive compliant. It will not respond to a 5 watt
walkie-talkie at distances greater than 1 foot (0.3 m). Do not
operate a walkie-talkie within 1 foot (0.3 m). of the X3301.
Non-Carbon Fires
The X3301 is a multiple spectrum IR device with detection
limited to carbonaceous fuels. It should not be used to
detect fires from fuels that do not contain carbon, such as
hydrogen, sulfur, and burning metals.
ImPORTaNT SafETy NOTES
WarnIng
Do not open the detector assembly in a hazardous
area when power is applied. The detector contains
limited serviceable components and should never
be opened. Doing so could disturb critical optical
alignment and calibration parameters, possibly
causing serious damage.
CaUtIon
The wiring procedures in this manual are intended
to ensure proper functioning of the device under
normal conditions. However, because of the
many variations in wiring codes and regulations,
total compliance to these ordinances cannot be
guaranteed. Be certain that all wiring complies
with the NEC as well as all local ordinances. If
in doubt, consult the authority having jurisdiction
before wiring the system. Installation must be
done by a properly trained person.
CaUtIon
To prevent unwanted actuation or alarm,
extinguishing devices must be disabled prior to
performing system tests or maintenance.
CaUtIon
The multispectrum IR flame detectors are to be
installed in places where the risk of mechanical
damage is low.
attEntIon
Remove the protective cap from the front of the
detector before activating the system.
attEntIon
Observe precautions for handling electrostatic
sensitive devices.
