The Gallagher SMB 8In 4Out Board extends the connectivity of the Gallagher Controller via the HBUS communications protocol. The board provides connection for 8 inputs and 4 outputs.  The HBUS communication is based on the RS485 standard and can communicate over a distance of up to 500m (1640ft) at a speed of 1 Mb/s.   

The SMB HBUS 8In 4Out board is secured using open standard, leading authentication and encryption.  Secure communication features are enforced automatically.  

Please note: SMB hardware can only be used as part of the SMB Cloud Solution.
