Potter Electric ZA-42 4 Zone 2 Signal Adder Card

Product Description

The POTTER ELECTRIC SIGNAL CO. US ZA-42 is a 4-zone, 2-signal adder card designed for use in fire alarm and waterflow monitoring systems. This expansion card adds zone and signal capacity to compatible control panels, allowing technicians to extend system coverage without replacing the base unit. It is sold as a single unit and is installed by licensed fire alarm or low-voltage technicians during initial system buildout or system expansion. The ZA-42 is suited for commercial and light industrial fire protection applications where additional zone inputs and signal outputs are required.
