pERIODIC ChECkOUT pROCEDURE
A checkout of the system using the Mag

or Man

feature should be performed on a regularly scheduled

basis to ensure that the system is operating properly. To

test the system, perform the “Manual

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

testing

• Easily replaceable

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.
