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 network using the 563-083 contact closure
transmitter and the QAA4292.EWSC temperature
sensor.
Communication between buildings, less than 250’ apart, is also possible with the use of strategically placed
repeaters. Use the Site Survey Tool to validate signal strength in these applications and ensure optimum number
and location of repeaters.
