independently from the Master and communicates through its UP port to the Master. Depending on the system design, the UP port of the Slave can be connected to either the DOWN port of the Master (when an additional Station is being used) or to one of the Master’s standard Sensor ports (P01 to P13). -
Page 37: Firesync Slave
These power supplies must be isolated! This means that DC ground is NOT tied to AC ground! LMI Technologies recommends the use of a Phoenix Contact, QUINT, 10 Amp power supply (for +48 VDC) and a Lambda DSP60-12 power supply (for +12 VDC). They are both DIN rail mounted device that can be connected in parallel to increase the overall available power. -
