7.8 Typical Small Window Version,
(each alarm window = 30mm w x 30mm h),
The above rear view shows a typical small window RTK 725B configured 4 cells wide x 2 cells
high with twenty eight active alarms, common relay card and an integral pushbutton module.
Each cell within the Annunciator is used to display four alarm channels.
In the example above cell 0 and cell 1 are equipped with a four channel alarm card plus
provision for three remote pushbutton inputs. As standard the pushbutton inputs are software
configured as follows:-
Cell 0 ---- P1 = Lamp Test / P2 = Ack / P3 = Reset
Cell 1 ---- P1 = System Test / P2 = Silence / P3 = 1st Reset
These can be reconfigured in software as required.
In small window versions of the RTK 725B each cell is supplied with an alarm card and the
outputs are distributed to four channels within the cell.
