Typical Medium Window Version,
(each alarm window = 60mm w x 30mm h),
The above rear view shows a typical medium window RTK 725B configured 4 cells wide x 2
cells high with fourteen active alarms, common relay card and an integral pushbutton module.
Each cell within the Annunciator is used to display two alarm channels.
In the example above cell 0 and cell 2 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 2 ----
P1
= System Test /
P2
= Silence /
P3
= 1st Reset
These can be reconfigured in software as required.
In medium window versions of the RTK 725B only the first cell in a group of two is supplied
with an alarm card and the outputs are distributed to the next cell – working down in columns
and then moving onto the next row.
