Introduction 

 

RFID reader WREM 81 MTM(VR) with wiegand output, reads media at 125 kHz (EM 
Marin) and is designed for connection to control modules and door controllers of the 
APS mini Plus or APS 400 system, or to third party controllers. The reader is equipped 
with a configurable WIEGAND data output usable with most third party systems. The 
reader is delivered in MTMRFID module dedicated for entry panel MTM. It contains two 
inputs (LED and buzzer control), as well as an 
RS 485 interface for configuring the wiegand output or fw update.
