First Alert VISTAHEXPHW - Data Sheet Dated 11/24

The VISTAHEXPHW hardwired zone expansion module
allows you to add 8 additional hardwired zones (16 with zone
doubling) per module to a VISTAH system. The module has
a built-in tamper allowing detection and reporting if the front
cover is removed and is supervised so if the wiring is cut
a supervision alarm will result indicating the module may
not be operational. The flexibility to mount the module on a
surface wall or to a gang box depending on the installation
environment and the terminal strips are removeable to give
installers easier access to help making wiring easier.
