A relay control button or an access sensor can be connected to the discrete input of the BioSmart 4 controller. To configure them, go to the Relay control and access sensor tab on the settings panel of the BioSmart 4 controller.

Configuring the relay control button

In the corresponding parameter group, configure the relay control button:

  1. From the Input drop-down list (1), select the input to which the button is connected: Aboard input, Input #1 RCU, Input #2 RCU, Input #3 RCU, Input #4 RCU. If the button isn’t connected, select the No value. In this case, further configuration isn’t relevant.

  2. From the Relay drop-down list (2), select the type of relay that will trigger by clicking the control buttons:

    1. Aboard relay—controller relay.
    2. Relay #1 RCU—relay 1 of BioSmart RCU (relay control unit).
    3. Relay #2 RCU—relay 2 of BioSmart RCU.
  3. In the Timer, ms field (3), enter the time of the active state of the relay after clicking the relay control button in milliseconds. The default value is 3000.

Configuring the access sensor

In the corresponding parameter group, configure the access sensor:

  1. From the Input drop-down list (4), select the input to which the access sensor is connected: Aboard input, Input #1 RCU, Input #2 RCU, Input #3 RCU, Input #4 RCU. If the access sensor isn’t connected, select the No value. In this case, further configuration isn’t relevant.
  2. From the Active state drop-down list (5), select Low level or High level of the signal that appears on the discrete input, at which the access sensor triggering is detected.
  3. From the Relay locking drop-down list (6), select the relay locking mode when the access sensor triggering is detected. On door opening—relay is disabled when the access sensor is triggered. On door closing—relay is disabled when the access sensor returns to its initial state.

  4. If it is necessary to consider an access event, select the On value from the Consider access event drop-down list (7). The default value is Off.

  5. If it is necessary to consider a door hack, select the On value from the Consider door hack drop-down list (8). The default value is Off.
  6. Click the Apply button to save the changes.
