Specifications; Mounting; Wireless Protocol - Trane BCHE Installation, Operation And Maintenance Manual

Installation - Controls
You can manually set the coordinator WCI so all WCIs
having matching addresses automatically join the network.
Wireless Zone Sensors
The WCI also communicates with Trane wireless zone
sensors, eliminating the need for analog receivers.
Wired Zone Sensors
Systems using WCI can also use wired zone sensors.

Specifications

Operating Temperature: -40 to 158ºF (-40 to 70ºC)
Storage temperature: -40 to 185ºF (-40 to 85°C)
Storage and operating humidity range: 5 percent to 95
percent relative humidity (RH), non-condensing
Voltage: 24 Vac/VDC nominal ± 10 percent. If using 24 Vac,
polarity must be maintained.
Receiver power consumption: <2.5 VA
Housing material: Polycarbonate/ABS (suitable for plenum
mounting), UV protected, UL 94: 5VA flammability rating
Mounting: Snaps into sheet metal opening.
Range: Open range: 2,500 ft (762 m) with packet error rate
of 2 percent.
Indoor: Typical range is 200 ft (61 mm); actual range is
dependent on the environment. See BAS-SVX55-EN for
more detail.

Note: Range values are estimated transmission distances
for satisfactory operation. Actual distance is job
specific and must be determined during site
evaluation. Placement of WCI is critical to proper
system operation. In most general office space
installations, distance is not the limiting factor for
proper signal quality. Signal quality is affected by
walls, barriers, and general clutter. For more
information os available at www.trane.com.
