NC-mod a keyboard
NC-mod4
This module is supplied in two designs. The NC-mod4 module has four buttons and includes the electronics to be connected to the basic module or to previous NC-mod4 module. This module is only connected by flat cable – buttons and lighting through is already interconnected. The terminals for connection of other four buttons and current supply of lighting are further placed on module (on following NM-mod4).
The NM-mod4 module is always connected to previous (in row starting with basic module) NC-mod4. The connection is not prepared and should be done by conductors – see on figure. The flat cable connection is facilitated by connector locks, preventing from rotation, but to keep the connection routing is imperative. “To NUDV” is always the routing to the basic module.“To Cmod” is routing to the row end (on last NC-mod.).
Module of keyboard NKLA
The keyboard module is only connected by flat cable as well as NC-mod4 module. The only difference is that keyboard module is always the last in row (no other module can be connected behind it) and it can be only linked to the first (directly to the basic module) or the second (to output of the first NC-mod4) positions. It means that 0 to 18 buttons with direct dialing can be used instead of keyboard (per assembly). The most frequent used assemblies are:
– NUDV2 + NKLA
– NUDV2 + NC-mod4 + NKLA
– NUDV2 + NC-mod4 + NM-mod4 + NKLA
Pay attention when programming – the position of keyboard connected must be correctly specified (parameter 48).
The choice is entered by gradual pressing of buttons with digits. Firstly the key symbol must be pressed to enter a password. When pressing X, the guard will hang up.
