SECTION 1 INTRODUCTION
The LN1000 annunciator is an intrinsically safe process alarm system certified for installation
in Zones 0, 1, 2 IIB and IIC hazardous areas.
The annunciator is a totally unique product which provides an ideal solution to alarm
monitoring problems where an operator needs additional information on the plant status and
control over external parts of the plant.
Being certified to Ex ia means there are no restrictions with regard to maintenance whilst the
power is applied as there are with Ex d, Ex p or Ex N equipment.
The annunciator system consists of three parts; the Chassis (12 way or 32 way), the
Sequence Card and the Alarm Card.
Each system will consist of the chassis complete with the Sequence Card, which controls the
common functions, and as many Alarm Cards as necessary to cover all the alarm points to
be monitored.
The power for the annunciator is supplied from the safe area through a single certified
isolating interface, which avoids the requirement for a high integrity earth. This single IS
interface is sufficient to drive up to 32 alarm channels.
The annunciator functions in a similar manner to a conventional, safe area annunciator, but
because of the limited power available the information is displayed using a combination of
high efficiency LED's and LCD’s in the place of incandescent lamps.
The system is fully programmable, via DIL switches, for a range of commonly used functions
and features. The alarm sequences are based on the sequences listed in the ISA publication
"Annunciator Sequences and Specifications" S18.1 -1979.
The operator can respond to alarms using either integral or remote pushbuttons.
The standard system is panel mounting to allow customers to incorporate it into their control
systems but if a stand-alone alarm system is required RTK can offer a wall mounting version
which is fully self contained in a stainless steel enclosure.
The LN1000 annunciator is available with a range of complementary products, manufactured
by RTK; these will allow signal transfer between hazardous to safe areas (DA-149 IS
Relays), provide higher volume audibles (DB-5 and DB-7 IS Sounders) and flashing beacons
(DA-135 IS LED Beacon).
With this range of products it is very easy to design and configure a comprehensive alarm
monitoring package for any hazardous area.

SECTION 2 SYSTEM DESCRIPTION & FEATURES
General
The LN1000 intrinsically safe annunciator is a totally unique product which allows operators
to monitor the alarm status of critical parameters in any hazardous area. Not only will the
LN1000 give detailed information of the plant alarm status but it can also be used to control
sections of the plant both in the hazardous area and, via isolating relays, in the safe area.
Certification
The LN1000 is certified by BASEEFA to Ex ia IIB T4, with the 8 way version being certified
by BASEEFA to Ex ia IIC T4. This certification is suitable for use in zones 0, 1 and 2.
BASEEFA certify that the product complies to EN60079-0 and EN60079-11
System Sizes
Two chassis sizes are available as standard, a 12 way (size used for 8 way and 12 way
units) and a 32 way.
The chassis always contains the Sequence Card which controls the common functions and
group outputs.
Each Alarm Card monitors two alarm channels, these are simply added to the chassis to
make up the alarm system of the required size.
Complete System
Figure 2.1 on the following page shows a typical system, those parts shown shaded illustrate
an alarm system in its simplest form.
All the complementary parts needed to design a more complex system are manufactured by
RTK and can be supplied together with interconnection diagrams.
RTK Instruments will help in designing systems and providing all components and details of
how the separate products interconnect.
Programmability
The annunciator alarm sequences, functions and features are programmable via the on-
board DIL switches.
This covers different alarm sequences, normally open or normally closed alarm contacts,
first-up groups, output functions and time delays.
Most features are programmable down to each individual alarm way.
Mounting
The standard system is supplied suitable for panel mounting for customers to incorporate
into their control systems.
A wall mounting version is also available for stand-alone systems, these are mounted in IP65
stainless steel enclosures and fully wired to terminals ready for on-site connection via the
bottom gland plate.

8
Servicing
As the LN1000 is certified as intrinsically safe, live inspection and maintenance procedures
can be carried out at any time.
All configuration and maintenance is carried out from the front by simply removing the front
fascia and withdrawing the cards.
Lightweight
Being constructed from stainless steel and polyurethane mouldings make the LN1000
extremely lightweight in comparison to conventional flameproof and Type 'N' systems. This
gives great benefits when space and payload are critical factors, especially offshore.
Group Outputs
A number of outputs are available as standard to drive external audibles and control other
parts of the plant in the advent of certain alarms occurring.
These outputs are programmable to operate in many different ways.
Inputs
The alarm inputs are normally situated in the hazardous area but can also be connected to
the LN1000 from the safe area if connected via IS Relays (Type DA-149).
The other inputs such as "alarm inhibit" and pushbuttons should all be local to the LN1000.
Terminals are available as standard to fit external pushbuttons if required and the integral
pushbuttons on the fascia can be disabled.

All connections to the LN1000 Annunciator are via rear mounted screw terminals. These
terminals are suitable for cables up to 2.5mm².
In the wall mounted versions the input and output terminals are wired to a row of
2.5mm²terminals on the backplane.
The Sequence Card and the Alarm Cards are all interconnected by a common backplane.
This backplane is used to supply power to the Alarm Cards, synchronise the flashing of the
LED’s, ascertain the first-up alarm in any sequence, connect the pushbutton controls and
provide a drive signal to the local horn, the external sounder outputs and all group outputs.
LN1000-AC Alarm Card
The Alarm Card monitors two alarm channels and each channel has the following inputs and
outputs:
ALARM INPUT: CONNECTED TO THE VOLT-FREE ALARM CONTACTS
INHIBIT INPUTS: Connected To Volt-Free Contacts To Inhibit That Alarm Channel
GROUP A OUTPUT: Configurable To Follow The Alarm Logic Or The Field Contact

SECTION 5 MECHANICAL DETAILS
Alarm Chassis
The annunciator consists of a stainless steel case with integral card rails.
The LN1000-12 is a single level unit, fitted with a LN1000-SC Sequence Card and up to six
LN1000-AC Alarm Cards.
The LN1000-32 is a double level unit, fitted with up to eight LN1000-AC Alarm Cards on the
upper level, with an additional eight LN1000-AC Alarm Cards and a LN1000-SC Sequence
Card on the lower level.
The cards slide into the card rails and push into the connector mounted on the backplane.
Each card is polarised to prevent incorrect assembly and are simple to remove and replace
without the aid of specialised tools.
Fascia Panel
The fascia panel is high impact resistant polyurethane, with a printed polyester membrane
including transparent windows to view the legends and displays. The internal pushbuttons
are attached to the rear of the fascia connected by a ribbon cable to the Sequence Card.
The fascia is removed by unfastening the retained screws, and lifting the front panel down
until it is held on the retaining straps
Alarm Cards
Each two-channel alarm card is fitted with an LED and a Liquid Crystal Display (LCD) for
each channel.
The LED follows the normal alarm sequence and the LCD indicates the sequence, field
contact status, first-up and inhibit state of the alarm channel.
To identify each alarm way when the system is in use traffolyte legends are used, these are
located in the front panel above the upper channel and below the lower channel.
Sequence Card
The Sequence Card assembly contains the pushbuttons for controlling the stages in the
alarm sequence and system outputs to control external audible alarms and other related
control equipment.
Panel Mounting
The standard annunciator enclosure is designed for panel mounting. The fascia and the case
to panel seal are protected to IP65.
The unit is supplied with a rear cable housing to aid installation. This is removable to facilitate
drilling and for mounting the enclosure.
It is recommended that annunciators are installed in dry locations protected from corrosive
atmospheres or direct sunlight

16
Wall Mounting
If the requirement is for a stand-alone wall mounting alarm system this can be supplied with
the wall mounted variant. In this version the IS Annunciator is mounted in a stainless steel
enclosure with the terminals wired and loomed around the hinge to a row of 2.5mm²
terminals ready for external connection via the bottom gland plate.
Channel numbering
The channels are numbered starting from the Sequence Card towards the left. With two
alarm channels on each card the lowest channel number is always the upper channel.
