26.3.4 Connecting control inputs

The fiber interface has two control inputs (see

figure 26.7). The control inputs can be used to receive signals from third party equipment that must trigger actions within the Praesideo system. The control inputs can be configured to act on contact make or on contact break (see section 43.6).

Control input 1 and control input 2 Resistance detection (supervision enabled): Cable short circuit

<2.5 kohm Contact closed

7.5kohm to12 kohm Contact open

17.5kohm to 22 kohm

Cable broken > 27 kohm

Resistance detection (supervision disabled): Contact closed

<12 kohm Contact open

> 17.5 kohm

It is also possible to have the cables supervised for short-circuits and open connections (see figure 26.8 and figure 26.9). Whether a control input is actually supervised or not is defined in the configuration.
