Fire Detection, Control Panels and System Accessories
The FP2023 splits QE20 100V amplifier outputs into short-circuit isolated speaker feeds.
You can use it as 2 × 4 outputs (two amplifier outputs into 4 + 4), or 1 × 8 outputs (one amplifier output into 8) by daisy-chaining inside the module.
If one speaker line shorts, the other outputs keep working.
