Controller - SmartRelay 3 system

The SREL3 ADV system is connected to the network via Ethernet. The Ethernet connection is PoE-capable, so an external power supply unit is not essential.

It is possible to use the system as a gateway in the virtual network. The controller establishes a connection to the VN host server to do so. The VN host server forwards changed authorisations (programming requirement) and data from the LSM database to the controller. This means that complete, time-consuming loading of the database is no longer required; instead, the controller collects the provided data when an identification medium is detected (pull principle). The entire system is programmed via a single interface – the controller.

The SREL3 ADV is also available in a ZK variant, which extends the system's functions to include time zone control and event logging (access lists).

Three available screw terminal inputs ensure that the controller is flexible in its use.

  • Forwarding to LSM (Inputs 1 and 2)
  • Push-to-open contact (Input 3)

The built-in screw terminal relay output can activate any system and open an electric door, for example.

An IP address needs to be issued using USB when the controller is programmed for the first time. Once the IP address is issued, a USB connection is no longer needed. The controller's configuration can be modified over the network instead.

The built-in backup battery ensures that the programmed settings are maintained after a power failure and guarantees that the controller continues to function without any limitations once power is restored.

NOTE

notice

Follow the switch-on sequence

After a power-on reset (power outage followed by restoration of power supply), the controller automatically searches for connected system components one time on restarting. System components which are not supplied power until the controller restarts are thus unable to respond to the controller's query and are not recognised.

The controller must therefore be supplied power with the other system components at the same time or must be the last system component to receive power.
