The Tina Duo unit can expand the number of sensors in a Vital/Pluto system. It creates a further dynamic circuit in which up to 30 active sensors, standard sensors with Tina or 10 off Tina Duos can be connected. It also permits resetting of the new sensors.

The Tina Duo splits the signal into two circuits (A and B). Circuit B is the expanded circuit where external reset is possible—circuit A is reset by the Vital/Pluto. The Tina Duo is equivalent in terms of timing to 3 (three) Eden or Tina units in circuit A. Two jumpers are located under the bottom cover. They define Manual/Auto-Reset and Even/Odd number of sensors between B1-B2.

The Tina Duo contains a “slimmed down” version of Vital that monitors circuit B. Therefore, it is possible to connect as many sensors to circuit B as for a “regular” Vital. It is, however, important to note that when a sensor is opened in circuit B, the fall-time of the main unit (Pluto/Vital) is increased by 30 ms. For each additional Tina Duo that is connected, it is possible to select local resetting with indication or automatic resetting.
