The Kentec K547 is an 8-way relay extender board for Kentec Syncro AS and Taktis fire alarm control panels. It adds eight individually programmable volt-free changeover relay outputs.
Up to 32 boards can be connected to the panel's RS485 bus, giving up to 256 extra relay outputs. They can be mixed with 16-channel I/O, 6-way sounder and 4-way conventional zone boards. All outputs can be driven by the panel's cause-and-effect logic.
