Bus (Optional); Z11/Z12 Relay Pcb And Z13/Z14 Digital I/O Pcb Features - C-TEC CAST ZFP Installation, Maintenance & Operating Manual

CAST ZFP Analogue Addressable Fire Alarm Panel
6 A-BUS (Optional)
A-Bus enhances the functionality of the CAST ZFP system by connecting peripheral PCBs which provide
additional relay outputs, digital I/O, sounder circuits and detection zones.
The A-Bus RS485 network protocol allows the interconnection of up to 15 A-Bus PCBs per Main 1 or 2-Loop PCB
using 2 core screened cable (plus 2 core for power). A-Bus PCBs are normally installed within a CAST ZFP panel
but can also work up to a distance of 1km for non-EN 54-2 functions. Two A-Bus PCB sizes are available; full and
half size. If required, a full size PCB (Relay & Digital I/O only) can be scored in the middle to produce a half size
PCB. The A-Bus PCBs are programmed using CAST ZFP Programming Tools (Part No. ZTOOLS).
