Honeywell, its affiliates, and licensors liable for any loss of data, loss of profit, or any loss or
damage, whether direct, indirect, incidental, special, or consequential, however arising, as a
result of accessing or using the software. So long as this provision is enforceable in Customer's
jurisdiction, the foregoing limitations, exclusions, and disclaimers apply to the fullest extent
permitted by law even if any remedy fails of its essential purpose.
In terms of North America flammable gas performance approval:
Honeywell BW™ Icon and BW Icon+ are performance tested only for the range 0-5% methane in
the air as 0-100% LEL based on CSA 60079-29-1 and UL 60079-29-1
Only Honeywell BW™ Icon and BW Icon+ infrared sensor were evaluated for CSA 60079-29-1
and UL 60079-29-1.
The evaluation is valid with flow rate 500ml/min, CH4 (Methane) gas, and Safety Suite Device
Configurator in CSA lab test.
The other options are not the scope of CSA 60079-29-1.
For the compliance of CSA 60079-29-1, the adjustable alarm point shall not exceed 5% to 60 %.
The highest alarm shall be configured as a latching alarm, and the user can turn on/off the
latching alarm by Safety Suite Device Configurator or Device Configurator.
Honeywell BW ™ Icon and Icon+ were pressure tested for 80 to 120 kPa, temperature tested for -
40°C to 60°C, humidity tested for 5% to 90% RH, gas tested for 2.5%VOL CH4=50%LEL and air
velocity less than 6m/s in CSA lab test.
The battery voltage is 3.7V, and the manufacturer verifies the duration time until the low battery
condition mentioned; the performance test in the CSA lab only verifies the low battery duration.
The maximum power consumption of BW™ Icon and Icon+ are 380mW.
Infrared CH4 sensor warm-up time is less than 45s, CSA lab calibrates after warm-up for 1 hour,
and test gas application time is 60s. T90<60s for 50%LEL CH4 gas in diffusion mode.
To check reaction time, follow the section of 'Capture Real-Time Reading' to enter
'Measurement' in DC and apply calibration gas. The reaction time starts from the time once
attached hose or applied gas and end when reading over 90% of calibration gas concentration.
Performance Test Temperature Dependence:
-20 to 60°C, ±5%LEL or ±10% of reading at 20°C, whichever value is greater
-40 to -21°C, ±10%LEL or ±20% of reading at 20°C, whichever value is greater
Reading shows 0%LEL below 3%LEL and indicates Negative alarm once reading below -
5%LEL. Use the utility of manufacture to disable the suppression of reading.
Where it is necessary to apply LFL and UFL values for CSA 60079-29-1 and UL 60079-29-1,
reference shall be made to ANSI/NFPA 497.
