VSR Spare Module

Sub Rack configurations include the options for both “front” and “back” modules. Front module is a display, programmer, or VESDAnet socket and Back modules are remote termination cards with a variety of relay options.

The VESDA Sub Rack can be configured in thousands of different ways. The modules will be assembled in the configuration you specify, from left to right. Position 1 is the far left position, while Position 4 is the far right. The Sub Rack mounts on any standard 19in rack. Sub rack enclosures are also available.

• All programmers and displays require remote termination cards
• Every relay termination card requires a display or relay processor board
• If you are using the sub rack for remote relays only, you must have a relay processor board in each position that has a relay
