NOTES:
• Specifications are based on the following conditions.
– Standard static pressure: 0.10 inWG (25 Pa)
• The protective function might work when using it outside the operation range.
• *Sound pressure level:
– Measured values in manufacturer’s anechoic chamber.
– Because of the surrounding sound environment, the sound levels measured in actual installation conditions might be higher than the specified values here.
