1. Introduction
The RTK 725 Series alarm annunciator is used to provide visual and audible warning that a process
has gone beyond set limits or to provide status only indication. The annunciator is manufactured from
universal cells, each 60 x 60mm, 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, which can be illuminated by conventional 28V filament lamps or by “fit and forget” LED
assemblies.
The assembled unit is fully field programmable which allows the user to enable a number of pre-
defined features to control the operation of the annunciator with regards to alarm sequence, horn
groups, common alarm groups or optional Modbus communications.
Selection of features is on a per channel basis with no special tools or programming knowledge
required. All programming is carried out from the front of the unit using the integral pushbutton /
programming module, which allows changes to be easily made during commissioning or at a later
date after the equipment has been installed.
Large and medium window version alarm cards are fully interchangeable within the annunciator, on
small window versions an additional card type is used for the 2nd pair of alarm channels but cards of
the same type remain fully interchangeable.
Reliability of operation is increased over conventional annunciators as each alarm card is fitted with
its own application specific integrated circuit (ASIC), which is capable of complete system control.
During initial power up one of the alarm cards will automatically act as a master controller with
regards to flash rates etc and in the event that this card fails or is removed another card will
automatically take over the role of master controller.
The standard unit is supplied with five integrally mounted common output relays, which are used to
provide 2 horn relay outputs, 2 group relay outputs and a multifunction relay output with
programmable function.
Additional options exist for more complex requirements including integrally mounted signal
duplicating relays on a per channel basis, bi-directional RS485 serial communications link and user
selectable time delays on each channel.
Accessibility for normal maintenance, lamp/LED changes, legend/filter changes and programming is
accomplished from the front of the panel without the use of special tools.

1.1 Installation
Unpacking
Once the item has been unpacked please visually examine the unit for any signs of transit damage
before installing the unit into the control system. If any damage has occurred please report the
damage to the freight forwarder and copy RTK. The alarm annunciator is supplied with panel
mounting clamps locked in place, however please check all packages to ensure that no additional
pieces are left in the box as any auxillary items like power supplies, horns, pushbuttons or spares kits
will be packed separately.
Please double check that all items listed on the packing list have been unpacked before disposing of
any packing material.
Basic principles of handling
There are some basic principles that everyone should observe prior to carrying / lifting a large
annunciator:
Ensure that the object is light enough to lift, is stable and unlikely to shift or move.
If the object is two heavy or awkward for one person to safely lift ask for help or use a
handling aid.
Make sure the route is clear of obstructions.
Make sure there is somewhere to put the load down wherever it is to be moved to.
Stand as close to the load as possible, and spread your feet to shoulder width.
Bend your knees and try and keep the back's natural, upright posture.
Grasp the load firmly as close to the body as you can.
Use the legs to lift the load in a smooth motion as this offers more leverage reducing the
strain on your back.
Carry the load close to the body with the elbows tucked into the body.
Avoid twisting the body as much as possible by turning your feet to position yourself with the
load.
WARNING!
Installation, configuration and maintenance of this annunciator must only be
performed by competent service personnel
