Control Panel System 42

The System 42 has been developed from the popular System 42 (S) specifically for particularly large projects. It is suitable for projects where the client wants to control the Fire/Smoke dampers from more than one location and minimises cable installation cost by reducing the necessity to run all of the control loops back to one main panel.

The System 42 is a purpose-made damper control system which operates via an RS 485 loop signal from each damper decoder to the main panel(s), and can have up to 8 master control panels networked together via a RS232 signal connected to each panel.

SPF Efficiency Information

Advanced Air damper control systems have been, and continue to be used, on a variety of different projects, including extensively on both new build and refurbishment Hospital projects.

When using the Advanced Air addressable system 42, you can be assured that with its true bi-directional communication, control and monitoring of the installed equipment can be achieved at all times. Maintenance or replacement of any damper or fan decoder is quick and simple. By using a ‘plug and play’ method, replacement decoders can be sent to site pre-programmed for installation by the Hospitals maintenance team. Eliminating the need for costly engineering visits.

A full technical description of the system components and requirements is available separately.

Typical LCD screen display.

Screen size is 120mm x 90mm

Main Control Panel

The main standard panel is 350mm wide x 600mm high x 120mm deep, constructed from galvanised mild steel with a textured polyester powder finish.

The panel has a glass lockable front door and comes as a surface enclosure complete with flush mounting kit for optional on-site installation.


The decoder is a small metal box, 200mm wide x 150mm high x 80mm deep. One of many connected in a loop in the system. The decoder controls the status of dampers or fans.
