  • Page 12: Introduction

    The extension module AMC2-4WE is equipped with four Wiegand type reader-interfaces plus eight inputs and eight outputs. Hence with the AMC2-4WE it is possible to double the number of readers on an AMC2-4W from 4 to 8. Figure 3.1: The extension module AMC2-4WE The AMC2-4WE can not be deployed as an independent controller but only as an extension module for the AMC2-4W.

  • Page 18 Each AMC2-4W controller can be extended with an AMC2-4WE extension module. The using of AMC2-4WE modules has no influence on the limit of the maximum of controllers in one system, because it is an extension to an AMC2-4W and not a controller.

  • Page 19: Installing

    The AMC2-4WE can be attached on a standard 35 mm (1.377 in.) mounting rail using a snap-in mechanism. Attach the AMC2-4WE into the upper edge of the mounting rail [1], then push down the device and snap it onto the rail by pushing it towards the back [2].

  • Page 20: Unmounting

    To remove the AMC2-4WE from a mounting rail, first remove all pluggable connectors. Push down the AMC2-4WE until the lower edge snaps out of the mounting rail [1]. Pull the lower end of the AMC2-4WE from the mounting rail [2].

  • Page 21: Opening The Case

    Notice! To open the AMC2-4WE, first remove all pluggable connectors. The AMC2-4WE case consists of a top cover mounted with a two-point snap-in closure on a chassis. To open the case, push down the two snap-ins with a screwdriver, then swing the cover down.

  • Page 22: Closing The Case

    Insert the hooks on the lower edge of the front cover into the lugs on lower edge of the plastic back cover [1]. Please ensure that the BOSCH logo is not upside-down. The upper edge of the front cover now aligns with the two-point snap-in closures on the upper edge of the back cover [2], and may thus be clicked gently into place.

  • Page 23: Cabling

    Cabling Notice! Risk of malfunction The cables used in the AMC2-4WE access control system are not prone to electrical interference. However, you should avoid routing cables close to heavy load switching cables and equipment. If this is unavoidable, cross the cable at right angles every 1 to 2 m (3 to 6 ft) to reduce interference.
