Introduction TOC 30 Series nnunciators 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 ackground: Display When not in larm larm Message: Flashing Red ackground: ddress 42xx Displayed When ddress is activated by control panel uilt in Relay &: ctivated When ddress 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 nnunciators can be used for door entry control. Use the digital inputs to interface with other systems such as fire alarms. s with detectors in the TOC-30 series the annunciators will interface with any IGD addressable control panel. TOC-30 nnunciators 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.

Up to 6 TOC-0 Detectors can be Daisy Chained to the Input TOC-0 Unit Spare I/O TOC-0 Unit 2 Spare I/O Relay Output The nnunciator 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 nnunciator. Example fit protection diodes when switching external DC loads.

ddressable Interface Wiring 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. n addressable highway can run for up to 000M but it must be ensured that the cable size is large enough to keep the supply voltage over 7V DC. Use the IGD cable sizing guide to check required cable sizes.
