Technical data

SMART RELAY SREL, SREL.ZK, SREL.ADV

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.
