Installation and User Instructions for S874-EX Keypad Readers The S874 is a contactless smart-card reader, with LEDs and keypad. The 20mA current loop communications. reader can be set to use Wiegand or The S874 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.

SMS User Guide, P/N 9600-0429, M2150 Access Control Design Guide, P/N 9600-0420, 1 Fit The Weather Proofing Kit When mounting outside, the gasket kit must be fitted:
a) Remove the backplate from the reader after screwing the securing screw C fully IN. b) Position the gasket between the back plate and the mounting surface. Note: For UL listed applications, use only manufacturer provided gasket, P/N 87X-GASKET. Mount the Backplate 2 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. You should find that the backplate has holes for connection to most standard electrical backboxes.

Set SW1 switch1 (USER F/B - audio feedback) to 1 for sound on, or 0 for sound off. 5 Using / Testing the Reader Present the card face-on to the reader until you hear a "bleep". Cards can be presented in rapid succession; there is no need, for example, to wait for "GREEN LEDs" to disappear before presenting another. If the reader has been enabled for user-code mode at the controller, you can gain access by pressing the O key, entering your card number, then pressing the P key. When faulted, the reader can not accept a card read. Check wiring for faults or replace reader. The reader is now working correctly. LED Status Indicator GREEN The lock is released and you may open the door. RED You do not have access rights to gain entry, or the reader did not read your card properly (in this case, present it again). YELLOW Enter your PIN. If you make a mistake, the RED LEDs are momentarily displayed, followed by YELLOW LEDs, to prompt you to try again. G4S Technology, 2012. 9600-0596.
