If you select time switchover, the following options are available to you in the 'Time-
controlled switchover' box (several options can be selected): 
1. Manual lock 
The door does not lock automatically after the pre-set point in time until an 
authorised transponder makes a booking after this time. 
2.  Automatic lock (basic setting) 
The door is locked precisely at the point in time specified in the time zone 
plan. 
3.  Manual unlocking (basic setting) 
The door is not unlocked automatically after the pre-set point in time until an 
authorised transponder makes a booking after this time. 
4.  Automatic unlocking 
The door is not normally opened after the pre-set point in time, but when the 
first transponder activates it. If you specifically want the door to unlock auto-
matically at the pre-set time, then select this option. 
5. Transponder, active 
- Always 
Normally, a transponder cannot be used during the release interval. However, 
if you wish the door to be locked whenever required (when everybody has left 
the building, for example), select this option. 
- Only if locked 
In this operating mode, the transponder is not operative during the unlocked 
interval. 
7.7 OMRON 
Only for SREL.ADV: many access control and time-and-attendance systems feature 
serial interfaces to connect card readers. A Smart Relay can also be connected via 
these interfaces, thus also allowing you to use SimonsVoss transponders in third-
party systems. 
Select this option on both the Smart Relay and the cylinder if you wish the Smart Re-
lay to transmit transponder data to a third-party system and a remote opening com-
mand to be sent from Smart Relay to a cylinder after clearance by the third-party sys-
tem. 
Set the type of external system under 'Interfaces'. The following options are available:
