FAQ
What does the model code X3301A4N23T2 mean?
Per the X3301 model matrix: A = aluminum housing, 4N = four 3/4 in. NPT ports, 23 = HART, relay and 0-20 mA outputs, T = SIL/FM/CSA/QPS/ATEX/IECEx approvals, and 2 = Division/Zone Ex d classification.
Is a mounting arm required?
Yes. Det-Tronics requires a Q9033 mounting arm: the Q9033A (007290-002) for aluminum detectors only, or the Q9033B (007290-001) for aluminum and stainless steel detectors.
What power does it need?
24 VDC nominal, 18 VDC minimum and 30 VDC maximum. Consumption without the heater is 4 watts at 24 VDC (5.2 watts in alarm); the heater adds up to 8 watts.
Does it need a test lamp?
No. The automatic optical integrity (oi) test checks the optics about once a minute and signals a fault when less than half of the detection range remains; a magnetic or manual oi test can also be run.
