5.2 LOCAL INPUT CONTACTS
Examples of connection of control inputs with programming of the inputs for use with:
Example A: activation contacts Normally Open WITHOUT monitoring of connecting line.
Example B: activation contacts Normally Closed WITHOUT monitoring of connecting line.
Example C: activation contact Normally open WITH monitoring of connecting line.
Example D: activation contact Normally closed WITH monitoring of connecting line.
When monitoring a connecting line, it is necessary to connect the balancing resistors in the proximity of the activation contact.
For details about the control input programming modes, refer to the Section on “set > CONTROL INPUTS” (see point 8.6.1).
5.2.1 Local input contacts for a 12-zone system
The two VAIE 2250 units, connected to one another so as to form a 12-zone system, are managed as two separate systems.
The contacts for activating the external peripheral unit have to be connected separately to each VAIE 2250 unit.
Reference should be made to the heading “set > CONTROL INPUTS” (point 8.6.1) for programming each contact connected for each
of the VAIE 2250 units.
Example A
Set the following parameters for INPUT 1:
• “Active if Close”
• “Surveillance NO”
