Note:
The entry panels used in the MDS City system are standard City Line 4+N panels to which a recess is added where
the MDS Digitiser Module is installed. The call extension modules are used as intermediary points between the 4+N
buttons and the MDS system.
Calls to residences are made by pressing the corresponding call button assigned to the residence. The button
determines the last 2 digits in the call address. The digitiser module determines the first 2 digits.
The MDS City Panels, cannot be used as General Entrance Panels.
