International Gas Detectors
TOC 30 Series Annunciators add extra flexibility to addressable gas detection systems, combining a colour
alarm display with E-Stops, Key Switches or other inputs.
Displayed messages are programmable as:
Safe Message: Green Background: Display When not in Alarm
Alarm Message: Flashing Red Background: Address 42xx
Displayed When Address is activated by control panel
Built in Relay &: Activated When Address is activated by control panel
Sounder
There are three digital inputs which are used by the control panel in the same manner as other addressable
inputs and have unique system addresses. Cause and Effect actions can then be programmed from the
system controller.
TOC-30 Series Annunciators can be used for door entry control.
Use the digital inputs to interface with other systems such as fire alarms .
As with detectors in the TOC-30 series the annunciators will interface with any IGD addressable control panel.
TOC-30 Annunciators are standard 2 gang fitting and as such can be used with standard plaster boxes or
dado rail to neatly fit into any environment.
Who should read this manual.
This manual is intended for use by trained installers of gas detection systems who are technically competent
and have all necessary tools to undertake installation and maintenance on this type of equipment.
Failure to install and maintain the equipment properly can render the system ineffective.
You should not undertake any of the procedures in this manual if you do not have access to the correct
equipment, have not undertaken training on this or similar equipment or are not technically qualified to install
this equipment.
Calibration gases and test equipment is available from IGD.

The Annunciator relay output can be used as an alarm interface to external systems, run additional
audio visual alarms or directly control other devices. Typical applications could be gas solenoid
valves, boiler shut down interfaces or similar. When switching external loads it is important to
consider the nature of the load being switched. For inductive loads suitable protection from induced
back EMF must be fitted. Many modern devices conforming to the European EMC Directive may
already have devices fitted as part of their design to limit in-rush currents and back EMF. Where
these are not fitted the following two diagrams provide guidance. Failure to observe this may result in
damage to the Annunciator.

The TOC-30 Annunciator is an Addressable Device and Comes
Equipped With a Simple Interface to Allow the Base Address to
be Set.
To Check The Set Address,
Press and Hold the Right Hand Button Labelled ‘DOWN’ For > 2s
Release Button the Light Pattern Will Now Indicate the set Address as Shown in the Table Below.
With the Set Address Lit, the UP and DOWN buttons can now be used to alter the address if required
With the Required Address lit, Press and Hold the DOWN Button Until the LED’s go out. Release the
DOWN button and the new Base Address is Now Set.
Note That the Left LED Will Now be Flashing if the Annunciator is Communicating With its Control
Panel.

For a Base Address Set of 4101:
NOTE: WHEN SETTING ADDRESSES YOU CANNOT HAVE TWO DEVICE ADDRESSES SET THE
SAME ON THE SAME ADDRESSABLE HIGHWAY.
E-Stop Input = Base Address = 4101
4102 = key Switch

Note: It does not matter which connector is used
as either the cable in or cable out connection
Devices can be in any order on an addressable highway but it
is advisable to install in address sequence as thi swill aid
future servicing
NOTE: WHEN SETTING ADDRESSES YOU CANNOT HAVE TWO DEVICE ADDRESSES SET
THE SAME ON THE SAME ADDRESSABLE HIGHWAY.
IGD addressable systems use a 4 core cable or highway to connect all system devices. Typically an
addressable highway will support up to 32 devices as any mix of gas detectors, addressable relays,
addressable inputs. You must not have duplicate device addresses on the same highway cable. Some
Controllers support more than one highway, in this case it is allowed to have the same addresses on
different highway cables on the same controller. An addressable highway can run for up to 1000M but it
must be ensured that the cable size is large enough to keep the supply voltage over 17V DC. Use the
IGD cable sizing guide to check required cable sizes.
120 W
At the last device on the
highway it is advisable if
the cable run is over
250M to fit a 120W
resistor across the A-B
terminals. This will reduce
‘noise’ on the highway
and aid reliability. Under
250M of Cable This is Not
Required.
