Series 4292 Wireless Sensor System A6V11664719 Revised 02.05.
Why Wireless? • Installation labor savings ≈ 50% vs.
Wireless Deployment Considerations Reliability Will the data packets consistently and securely make it to the network? Range What is the transmission range? Scalability Can the system expand with my facility? Can the system be applied across multiple buildings? Battery Life Will battery replacement be a service challenge?

Un
How is 25 Year Battery Life Realized? • Series 4292 Wireless Sensors are engineered for very low power consumption which enables dramatic improvements in battery life vs.
Series 4292 Sensors Offer Proven Performance • The Series 4292 Wireless Sensor concept has been validated via Fast Accelerated Life Testing • • Firmware on test units was modified to change packet transmission interval from 1 per 66s to 1 per 143ms • Test represented an acceleration factor of 462, resulting in the sensor transmitting as many packets in one day as a normal sensor will transmit in 15 months • Sleep current and battery self-discharge current were also subject to an acceleration factor o
Series 4292 System Sample Architecture • Sensors transmit temperature, humidity, air quality, and dry contact status to the gateway directly or via wireless repeaters • Wireless repeaters (where necessary) transmit data directly to the gateway or via other repeaters • System gateway sends data to the BAS via BACnet or Modbus • 915mHz wireless frequency eliminates conflicts with WiFi networks and enables data transmission between rooms, between floors, and even between buildings!
