Introduction
Power Connections
Power Connections
The 301C requires a power range of 17-27 Vac, 50/60 Hz (8.64 VA),
18-36 Vdc, 350 mA @24 Vdc (8.4 VA). Polarization is not important in
either AC or DC mode. The system must be grounded on the
transformer and a dedicated circuit breaker must be used.
Communication Connections
Communication cables must be grounded using the shield terminal,
using twisted and shielded pair Belden 2-24 AWG #9841 cable (or
equivalent).
The network cabling can extend up to a limit of 2000 feet (609 m) per
channel.
The length of a T-tap can reach 65 feet (20 m), up to a maximum of 130
feet (40 m) for all T-taps.
Note: Channel 4 is the slave communication channel: No transmitters
may be connected to this channel. Ex.: Channel 4 can be used
for the BACnet (slave) connection.
All wireless devices associated to the controller will automatically be
detected and communicate with the controller using wireless
communication protocols.
