V+ F3
Evtl. Widerstand zur
Leistungsbegrenzung.
Der Ausgang V+ liefert
max. 10 mA bei 3VDC
Entweder Buzzer oder LED
Possibly resistor for restricting power 
The V+ output supplies a max. 10 mA at 3 VDC 
7.13 Interface 
Only for SREL.ADV 
For operation as a serial interface, you can select the type of card reader here that 
the Smart Relay should simulate. You have the following option’s: 
  Wiegand 32 bit   
  Wiegand 26 bit 
 Primion 
 Siemens  
 Kaba Benzing 
 Gantner Legic 
 Isgus 
You will find the corresponding cabling information in the chapter "The Smart Relay 
as a Serial Interface". 
7.14 Restricted range 
If you select this option, the reader range from the transponder Æ Smart Relay is 
restricted from approximately 1.5 m (4.9 ft) down to 0.4 m (1.3 ft). For example, you 
can use this option if there are several Smart Relays close to one another and 
individual transponders are authorised for several Smart Relays. 
7.15  External Beeper/ External LED 
Only for SREL.ADV 
Normally, the Smart Relay is configured for connection to an LED. If you want to 
connect a beeper or buzzer as the external signaller, mark this option. In this way, the 
beeper/buzzer can be used for an acoustic acknowledgement, instead of the LED. 
Should the connected component need less than 10 m maximum current at 
3 VDC, the connecting plan can look as follows:
