First Alert VISTAHEXPHW VISTA H Zone Expansion Module

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.
