SECTION 1 - INTRODUCTION
General
The RTK 725B Series alarm annunciator is 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 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.
Large, Medium & Small Window Sizes
Programmable Features
The 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 RTK supplied 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.

Glossary of Terms
Cell: A single module 60mm x 60mm which can be joined to adjacent
cells in varying heights and widths to provide the number of
alarms required. The number of alarms available per Cell
depends on the window size required.
N/C: A Normally Closed contact which opens in the abnormal state.
N/O: A Normally Open contact which closes in the abnormal state.
EN: Energised Relay Coil that De-Energises in the abnormal state.
DE-EN: De-Energised Relay Coil that Energises in the abnormal state.
Form A: Normally Open Single Pole, Single Throw Relay (SPST) contact
that closes in the abnormal state.
Form B: Normally Closed Single Pole, Single Throw Relay (SPST)
contact that Opens in the abnormal state.
Form C: Changeover contacts, Single Pole, Double Throw (SPDT)
contact both poles change in the abnormal state.
FCV: Field Contact Voltage. (Wetting Voltage)
Card: Refers to individual electronic circuit boards. There are various
types of Cards used within the 725B i.e. Alarm Cards, Relay
Cards, Supply Cards and Communication Cards.

Product Overview
The 725B is a modular alarm annunciator constructed from 60mm x 60mm
cells to form a single unit suitable for mounting in a panel cut-out. This
modular design allows units to be constructed in vast range of heights and
widths to suit individual panel designs and allows systems to be supplied from
a single alarm to a maximum of 256 alarms per annunciator.
