Sensor Warm Up Times
WARNING!
For optimal sensor performance, allow sensors 24 hours to acclimate to application conditions before performing an initial calibration.
Failure to follow this warning can result in serious personal injury or death.
XIR PLUS: ≤ 5 min
H2S: ≤ 5 min
SO2: ≤ 5 min
Cl2: ≤ 10 min
NH3: ≤ 5 min
Cat Bead: ≤ 5 min
CO: 30 min (Table 3 )
O2: 30 min
Carbon Monoxide sensor gas codes 10, 11, 12, and 14 may require initial warm-up periods longer than 30 minutes. If the 30-minute warm up is over, the sensor may show a positive reading that exceeds alarm levels. In the event of a short-term power outage, the warm-up time for carbon monoxide gas codes 10, 11, 12, and 14 will be significantly less. See Table 3 to estimate required warm-up time.
| Reading Level | <10ppm1 | <1ppm |
|---|---|---|
| Time left unpowered | Time to warm-up | |
| 1 minute | <5 minutes | <5 minutes |
| 8 hours | <30 minutes | <30 minutes |
| 5 days | <30 minutes | 2-4 hours |
| 1 month | <2 hours | 6-10 hours |
1 The minimum alarm level of all three CO sensors is 10ppm. Below this level would not cause an alarm on the device.
