3 Performance Specifications
3.1 Reliability
MCBF Environment
Unit reliability = 500,000 POH (based on component analysis)
Equates to a failure rate of 1.7% per year over the useful service life of 5
years.
Indoor Residential
Switching reliability = 100,000 MCBF operating both relays at 10 A resistive
load
Indoor Residential
3.1.1 Reliability Testing
The reliability specification is tested at 120 VAC, 10A load while maintaining ZigBee radio communication.
• The radio shall not reset during device switches.
• ZigBee communication shall not be degraded by a consumer noticeable level during normal
operation.
3.2 Power
3.2.1 Power Source
The unit is powered from a standard US 120 VAC +
10% source @ 50-60Hz. The unit operates over an
input range of 100 to 150 VAC.
3.2.2 Power Consumption
AC Power Consumption is 0.6 W in quiescent state, ranging up to 1.5 W during RF transmission and all
LEDs illuminated. 50ms surges of up to 0.5W additional power draw can occur when relay state changes
are activated.
3.2.3 Noise Rejection
The unit meets ANSI C37.90a Surge Withstand Capability and other immunity requirements as specified
in the agency requirements in Section 7.
Furthermore, no permanent damage to the unit will occur if noise on the AC power line is below the
following specifications:
• Motor noise spikes of an extra 30V peak on top of the nominal AC line voltage and frequency
3.2.4 Power Cycling
The unit shall perform without failure through 3600 power cycles. This is based on a use case of 2 power
cycles/day over 5 years.
Testing to validate this spec is done by cycling power for 5 seconds on, 30 seconds off, repeated 7200
cycles on a population of 4 units. This provides ~80% confidence this spec is met.
