NOTE!

  Up to 1200 m cable can be used. 

The 1728 unit can run in one of two different SW modes: 

a)

  

1728 in SW mode

 

1728 – 1587

 has the highest performance with regard to functionality, 

response time, ability to store fire alarms, etc.  In this mode it is intended to succeed the Display 
unit 2236SE but not as a spare part, since 2236SE is connected to a COM loop and 1728 
requires an Ext. FBP / DU interface board 1587 in the EBL512 c.i.e.  It is also intended to 
succeed the Ext. presentation display 2428SE but not as a spare part, since 2428SE requires an 
Ext. FBP interface board 1582 in the c.i.e. and 1728 requires an Ext. FBP / DU interface board 
1587 in the EBL512 c.i.e.  

b)

  

1728 in SW mode 1728 – 1582

.  In this mode it has the same functionality as the ext. 

Presentation display 2428SE and can be used as a spare part, i.e. the performance is the same 
but the look, dimensions, etc. are not the same.  In this mode 1728 requires an Ext. FBP 
interface board 1582 in the c.i.e.
