7.1.2. Control inputs configuration
CDG control panel inputs can operate in 2 modes:
- State control
- Activation control
- Alarm input
The first mode allows for output state control in order to assign its states with relay activations. In
this mode, the users decide only whether short circuit and opening states should result in fault
signalization.
Activation control mode is intended to manage devices using the control panel. This allows for
continuous control over external devices and for reporting information on their incorrect operation.
In order to control a device it must be equipped with contacts that feedback its state. An example of
the connection is depicted in figures 5.3.1 and 5.3.2.
In the Activation control area, select an output to which the controlled device is connected.
In the activation control mode users select activation and deactivation delays. This time allows the
device to change its state. The delay time is starts after each control relay state change. If the state of
the device control output will not change within the delay time the control panel reports controlled
device defect.
Fig. 6.7.2 PK1 and PK2 outputs activation control
Alarm input mode allows for reception of alarms from external devices other than detectors
connected using a detector line. In this mode, resistance levels are set for which the control panel
should report different alarm levels. The alarms received from control inputs exert influence on the
general alarm state of the control panel.
