OE5S874CSmartcard reader with keypad for access control systems 874 MKII

Mount the backplate using countersunk headed screws adjacent to the opening edge of the door. If fixing hole ’A’ is used then the breakout must be removed and the screw must not protrude. Feed the cable from the controller through the backplate. If the wall tamper function is to be used then the small hole in breakout ‘B’ may be used to mark the position of the wall screw before the breakout is removed. An appropriate wall screw should then be adjusted in height to protrude through the hole to activate the tamper lever. The front cover is secured to the backplate by UNSCREWING the securing screw ‘C’ via the small hole in the enclosure so that the screw head locates in the counterbored hole on the inside of the enclosure. The screw should not be removed from the backplate. 2 Mount the Backplate The S874-EX-KP V4 is a contactless smart-card reader, with LED’s and keypad. The reader can be set to use Wiegand or The S874-EX-KP V4 reader will read smartMAX encoded MIFARE cards and card serial numbers from most ISO 14443A smart cards which have a 4-byte UID (User Identification). The reader may be configured to read other card types by presenting a programming card to the reader during start up. For additional information regarding the installation, configuration and proper use of this product: SMS User Guide, P/N 9600-0429, M2150 Access Control Design Guide, P/N 9600-0420.
