B426/B426-M Conettix Ethernet Communication Modules
The B426 Conettix Ethernet Communication Module is a four-wire powered SDI, SDI2, or
Option bus device that provides two-way communication with compatible control panels over
IPv4 or IPv6 Ethernet networks.
Typical applications include:
– Reporting and path supervision to a Conettix Communications Receiver/Gateway.
– Remote administration and control with A-Link Plus or our Remote Security Control
application for handheld devices.
– Connection to building automation and integration applications.
The B426 is built for a wide variety of secure commercial and industrial applications. Flexible
end-to-end path supervision, AES encryption, and anti-substitution features make B426
desirable for high security and fire monitoring applications. It is capable as a stand-alone path
or it can be used in conjunction with another communication technology. For Fire Monitoring
applications, the B426 meets UL864 and NFPA72 standards for Single Communication
Technology with approved Bosch control panels.
B450/B450-M Conettix Plug-in Communicator Interfaces
Notice!
For B450-M only: Scan the QR code with your smart phone to access the control panel app
RSC+.
The Conettix Plug-in Communicator Interface is a four-wire powered SDI2, SDI, or option bus
device that provides two-way communication with compatible control panels over commercial
cellular networks using a plug-in communicator (available separately).
Use the B450 in combination with a plug-in communicator for primary or backup alarm
communication, remote control panel programming and other remote applications. The B450
supports Conettix IP protocol with full authentication, 256 bit AES encryption and resistance
to Denial of Service attacks. Use the B450 to add cellular network communications to existing
or new commercial security and fire installations.
