INTRODUCTION

General
The RTK 725B range of alarm annunciators are used to inform the operator that a
process has gone beyond set limits using visual and audible alarms.
The Annunciator is manufactured from universal cells which can be assembled in an
array to provide the number of rows and columns required to suit individual panel
designs. Each cell within the annunciator is able to contain either:- one large, two
medium or four small alarm windows (see Figure 1.1) and the window is illuminated
by “plug-in” universal white LED’s assemblies providing a maintenance free solution,
a reduction in power consumption and lower heat dissipation.

Programmable Features
The RTK 725B is equipped with a host of customer selectable features which can
be accessed via a USB programming port located behind the pushbutton face plate.
Once connected to a PC running the configuration software the user can enable or
disable pre-defined functions as required. Selection of features is on a per channel
basis with no special tools or programming knowledge required.
The Pushbutton assembly can be used to view the dynamic state of all signal inputs
and to set the non alarm state of each alarm to normally open or normally closed as
detailed in later sections.
