First Alert VISTAHRELAY - Data Sheet - Dated 11/24

The VISTAHRELAY module allows up to four hardwired, form-C
(SPDT) relay outputs per module to be added to the VISTAH
series control panels. It is mounted remotely and wired to the
control panels iBus wiring terminals for power.
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.
