Xtralis VSR-0031 Sub-rack with 2 x blank plates, VESDAnet

The VSR-0031 is a VESDA 19-inch sub-rack, one of 168 fixed-configuration order codes that let remote VESDAnet modules reside on VESDAnet while being physically mounted inside a glass-fronted enclosure such as an FACP enclosure. Each sub-rack holds up to four remote modules — remote displays, programmers, VESDAnet sockets and relay modules — supporting primary reporting and centralised monitoring and control of the VESDA system across VESDAnet, with the module mix customisable to site requirements. This particular code ships as a fixed configuration; the source does not itemise which modules and quantities it is pre-built with.
