DetTronics X3301 Multi IR Detector



The X3301 delivers fast fire detection performance while limiting nuisance and false alarms. Versatile, robust, reliable, developed and built with the needs of hazardous and critical industrial process operators in mind.
  • Multiple sensitivity modes
  • Optical Integrity (oi®) performs automatic fail-safe checks every 60 seconds
  • Heated optics for adverse environments and weather
  • Data logger with event time and date stamping (1500 events) 
  • Longest FM Approved detection range
  • Operating Voltage: 24 Vdc. Operating range is 18 to 30 Vdc. Maximum ripple is 2 volts peak-to-peak.
  • Power Consumption: 4 watts minimum (without heater), 17 watts at 30 Vdc with EOL resistor installed and heater on maximum.
  • Relays: Contacts rated 5 amperes at 30 Vdc.
    Fire Alarm: Form C (NO and NC contacts); normally de-energised: latching/non-latching
    Fault: Form A (NO contacts); normally energszed; latching/non-latching
    Auxiliary*: Form C (NO and NC contacts); normally energised; latching/non-latching.
  • Current Output*: 0–20 mA (± 0.3 mA), with a maximum loop resistance of 500 ohms from 18–19.9 Vdc, 600 ohms from 20–30 Vdc.
  • Temperature Range: 
    Operating: –40°C to +75°C
    Storage: –55°C to +85°C
    Hazardous location ratings: –55°C to +125°C 
  • Humidity Range: 0 to 95% relative humidity, can withstand 100% condensing humidity for short periods of time.
  • Spectral Sensitivity Range: 4 - 5 microns.
