• RF Transmitters connect to sensors or meters and send data to the infrastructure internet

connected Gateway on site

• The Gateway stores and transfers the data to the Realtime Online cloud server over a secure

mobile cellular connection

• Realtime Online provides a web based portal of visualisation dashboards, reports, graphs and

transmits out tailored automatic reports and notifications in the event of exceptions

1. Introduction The Chatterbox-e is a Pulse-Splitter that is designed to split the pulse signal from a Gas meter to several dataloggers. This then enables a Pulse transmitter to be fitted to a system that already has logger attached. Therefore, mirroring the pulse data onto Realtime-Online. The Chatterbox-e provides safety isolation between equipment generating pulses in the hazardous area and non-intrinsically safe equipment located in the safe area. Opto - isolators provide four isolated volt-free contacts from low frequency pulses generated by meters, pulses or correctors installed in the hazardous area. Chatterbox-e operates from a self-contained power supply and is suitable for installation in remote and environments without the need for an external power supply. The unit has four independent circuits that transform high impedance pulses, or volt-free contact closures, into isolated volt-free contact closures. One input can be connected to up to 4 isolated output circuits by using internal switches.

1.1 Technical Specification • 10 Year battery life from two 1/2 AA lithium cells. • Standard four channels • Channel selections via switches on the circuit board • Standard two output connectors • Certified Intrinsically Safe • Weatherproof cast aluminum NEMA 4X • Compliance to Article 500 of the National Electrical Code®, ANSI/NFPA-70 (NEC®) • Opto isolation increases reliability and reduces power consumption • Simple mechanical and electrical installation • Single or multiple outputs from single input • No Corrector or Meter setting required; as soon as the Chatterbox-e receives an input pulse, a 220ms isolated output pulse is generated

1.2 Inputs Each input is designed to interface with the current 'sinking' pulse outputs of the ROOTS® Micro Corrector to a maximum of 7.4V. The input will also interface directly with a volt-free contact closure, i.e., directly to a gas meter. Contact debouncing as standard.

1.3 Outputs Each output is a 220ms pulse, current sinking output capable of accepting up to 20V, 130mA.

1.4 Enclosure Weatherproof aluminum enclosure NEMA 4X rated. Size: 6.4” width, 4.8” height x 2.5” depth.

1.5 Intrinsic Safety BASEEFA 05 ATEX 0429 II (1) G [EEx ia] IIC. The Chatterbox-e must be installed in the safe area and is suitable for connection to equip-ment in hazardous areas Class 1 Division 1, Groups C and D.



1.6 Power Supply Two 1/2AA Lithium cells giving an estimated life in excess of 10 years based on all four channels operating and an input frequency of <1 Hz from a volume converter.

1.7 Battery Life

The below chart shows operational conditions in relation to Battery Life when in use.

2. Installation of a Chatterbox The Connection to Gas meters’ Requires an MPU (Meter Point Utilization) agreement filling in and sending to the Gas meter asset owner, before any connection is made. There are different Suppliers and asset owners across the country that will need to be contacted to obtain the relevant MPU document to fill in. The details of the Meter asset owner can usually be found via the sites MPRN number and the sites energy bills. There are many different types of Gas meter connections. The associated gas meter is required to

have a fitted pulse output module. In general, there are two main types of plug connection to these

meters which are

• RJ11 connection Fisher Plug Connection

Every connection into a chatterbox is polarity sensitive, if the two input connections don’t

show an output, the two wires will need swapping round.



Below shows how to wire a chatterbox to a pulse transmitter several instances.

Example 1

Example 2



Example 3

The Chatterbox has FOUR Independant Outputs that are configurable by changing the positions of

the switches within the Chatterbox to suit a specific application. One or more of the inputs may be

commoned by the use of the switches to provide isolated single or multiple outputs.

The Location and switch settings are shown below.

Example of single pulse transmitter connection.

• Step 1: Open the chatterbox using the correct alan key. • Step 2: Select Switch Position A=up, B=down, B=down. To duplicate the pulses on output

two for testing. • Step 3: Wire the pulse input coming from the fischer plug to the terminals labelled INPUT.

Please observe polarity.1 is + and C is -. • Step 4: Wire the Pulse Transmitter to Output 1. Please observe polarity marked + and – on

the terminal blocks. White = + Black = -. • Step 5: Wire into the 2nd Output Terminal with a LED Pulse Counter (700-700-7005)observe

polarity marked + and – on the terminal blocks. While the gas meter is consuming gas the



pulse counter should increase. This gives confidence in the correct connection/operation of installation.

• Step 6: When correct operation is confirmed remove the LED pulse counter and change the switch settings back to all Down. This helps extend the battery life of the chatterbox.

• Step 7: Close the enclosure using the screws provided.

2.1 Safety Warnings • No user serviceable parts inside. • Observe the instructions and all warnings on the device and within these instructions. • The installer/end-user is responsible for safe installation. • Local working practices should be adhered to for installation. • The enclosure of the device should be fully fitted.

Use of the Device in a Gas/Potentially Explosive Environment The chatterbox must be fitted in a non-hazardous area and relevant risk assessments need to be followed before entering and working in a gas meter zone area. This equipment can only be fitted locally to low pressure gas systems, usually coloured yellow. If there is a request to fit this equipment onto High Pressure systems usually coloured RED. Further clarification is required via the Gas Supplier.
