The TwinflexPro² Conventional Expansion card will provide 4 conventional zones. Therefore a TwinflexPro² panel fitted with a Conventional Expansion card would have zones 1 to 4 as Twinflex zones and zones 5 to 8 as conventional zones. The card is only compatible with the 4-zone TwinflexPro² panel. It is not compatible with the 2-zone TwinflexPro² panel or with any earlier TwinflexPro or TWINFLEX® Checkpoint Plus panels.
Note: conventional zones cannot distinguish between smoke or MCP fire signals.
