3. MULTIPLE SPEECH PATHS - OPTION 2 DECK ACCESS
To help speed the passage of visitors through large deck access systems the floor level functional panels can be
connected to additional distribution nodes to provide an additional speech path per floor. The example below
would allow all floor level functional panels and the main entrance door panel to be used at the same time to
call different flats.
Note: Trade and power connections must be linked between the distribution nodes on each floor level.
Additional lock power supplies are recommended for each door panel or a boxed PAC Easikey 250 could be used
for every 2 floors.
