System Overview
The Series 4292 Wireless Sensor System utilizes no-maintenance, battery-powered
sensors that transmit temperature, humidity, CO
2
, and contact status to gateway at a
916MHz frequency that minimizes interference from WiFi networks and improves
transmission through walls, floors, and windows. Each gateway receives data from up
to 100 sensors and interfaces the BAS via BACnet® MSTP, BACnet® IP, or Modbus
RTU and TCP.
Innovative power management technology enables 25-year battery life (15 years on a
CO
2
sensor). Fixed sensor transmission intervals to the gateway that maintain the most
recent sensor reading. This ensures constant data availability to the BAS while
maximizing battery life.
Sensor data is transmitted up to 300 feet, line-of-sight to a gateway. Repeaters can be
used for extended distances, or hops between floors and walls.
Series 4292 wireless sensors can be configured off-site and deployed in minutes at the
project site, resulting in reduced installation costs and minimal occupant disruption.
System Architecture
The Series 4292 Wireless Sensor System architecture consists of up to 100 sensors
that transmit data to the gateway which in turn interfaces with a building automation
system or other building controller. Gateway options provide a choice of BACnet
MS/TP, BACnet IP, Modbus RTU or Modbus TCP protocols for easy connection to any
building automation system.
Wireless repeaters may be necessary if the wireless transmission distance exceeds
300’ (line of sight) from the gateway or when the sensors and gateway are separated
by building floors or walls that may diminish signal strength. The sensor transmits data
back to the gateway via the mesh style repeater, or series of repeaters, up to 10 total
“hops” back to the gateway.
Additional analog sensors (NO/NC contacts and 10k Ω Type 2 thermistors may also be
tied into the wireless net-work via the contact closure transmitter (Part Number 563-
083) and the temperature sensor (Part Number QAA4292.EWSC).
