1An Introduction to the R3 19 inch Rack The R3 control system comprises a number of different plug in modules, each of which is dedicated to a particular function within the complete control panel.Modules cover all requirements -Fire detectionAlarm signallingGas detectionExtinguishingData transmissionPlant controlThe modular approach means that the system is inherently reliable, easy to install and commission and easy to maintain, repair and fault find.
2R3 19 inch Rack ApprovalsIn addition to Control Equipment’s range of quality system and company approvals, the R3 rack panel is approved by a number of bodies to various rigorous standards.The R3 panel is type approved to BS 5839 Part 4 and Lloyds Test Specification No: 1 (ENV 2 level) by Lloyds Register.Approved to BS 3116 Part 4 by The Loss Prevention Certification Board.The R3 is also approved to carry the CE mark in accordance with European Union directives 91/263/EEC and 89/336/EEC.In addition, the rack panel has been fully tested and approved by the Shenyang Test Centre in the Peoples’ Republic of China.

4Construction Modules are located within a 3U high sub rack. A legend plate may be located underneath each sub rack.Cabinet sizes are flexible within the constraints of the 19 inch rack.From 380mm high x 600mm wide x 369 deep for a single rack to 2000mm high x 800mm wide x 600mm deep for a system containing 10 racks.
5Cabinets All standard cabinets are at minimum IP55. Constructed of 1.5mm steel, coated with an electrophoresis primer and flint grey surface coat.Within the standard design, indications and controls are mounted in an aluminium framed lockable door and are visible behind a full sized polycarbonate window.The R3 rack system is very flexible and other cabinet constructions can be incorporated.
6What We Need to KnowDo you have any special cabinet requirements? for example -Special colourIP ratingSizesFor the purposes of quotation we need the following information -Input and output requirementsPower requirementsHardware requirementsApproval and specification requirements
7Planning the DesignUp to fourteen 19inch racks may be incorporated into a system, subject to cabinet size limitations.When planning the design of the R3, the following should be considered -all racks, identification plates and special switch plates need to fitall internally mounted equipment, terminals, power supplies, special equipment etc. need to be fitted.

10Common Control ModuleEvery R3 system must contain a Common Control Module.This module incorporates all executive action user controls.There are two types -K Conventional systems onlyK Both analogue addressable and conventional systemsThe Common Control Module is always fitted in the right hand module position of its designated rack.
11K1215 Decoding ModuleUsed in second and all subsequent racks to control data flow between rack modules and the system common control module (K1339 or K1321)
12Blank Sub-Rack Assembly Space allocated for K1339 Common Control Module.This is the basic layout of a sub-rack assembly. Each rack must have 1 Common Control Module and a Decoding Module where more than 1 sub-rack is required.Maximum number of modules per rack -K1321 Common Control - 14 modulesK1339 Common Control - 10 modulesK1215 Decoding Module - 14 modulesSpace allocated for K1321 Common Control Module or K1215 Decoding Module.
