7.7.2 NO AUDIBLE PROGRAMMING ACKNOWLEDGEMENT SIGNALS
SREL.ADV only
You should check this field if you do not want audible programming acknowledgement
signals to be emitted from a connected buzzer or beeper while you are programming
Smart Relay.
7.7.3 EXTERNAL LED / EXTERNAL BEEPER
SREL.ADV only
This indicates which external component group is connected. In flip flop mode, Smart
Relay emits a permanent signal when switched on if there is an external LED; in the
case of a beeper, an audible signal is only emitted when there is a change of status.
7.7.4 INTERNAL/EXTERNAL ANTENNAS
SREL.ADV only
- Auto-detection
If an external antenna is connected, this is the one which is used. Smart Relay
switches off the internal antenna in such cases. If no external antenna is con-
nected (standard case), Smart Relay functions with the internal antenna.
- Both active
Smart Relay is able to use both antennas to verify transponder bookings.
7.7.5 NUMBER OF EXTENSION MODULES
This is where you indicate the number of external modules connected to the Smart
Relay. These modules are connected to the terminals RS-485 COM, RS-485 A and
RS-485 B. You will find more detailed information in the documentation for individual
modules.
7.7.6 PULSE LENGTH
This is where you indicate the number of seconds for the switch pulse duration. The
value can be set at 0.1 to 25.5 seconds. If you enter 3 seconds, for example, an elec-
tric strike is released for 3 seconds before it locks again.
