Ellab Monitoring Solutions Ltd offers a range of battery powered iSense Transmitter/Sensors which send collected data to Hanwell applications via the GSM cellular phone network, rather than via low power wireless signals.
•iSense devices are supplied with either a standard SIM card or, for ruggedised versions of the ISense Transmitter, an encapsulated Chip SIM already installed and pre-configured to point at the Hanwell Data Routing Service.
|Note:||SIM cards with a data contract are required for the standard SIM, non-ruggedised, version.|
The customer can supply their own SIM card for the standard SIM versions, but will still have to pay an annual fee for the Hanwell Data Routing Service.
A Data Contract is required for ruggedised versions of the ISense Transmitter with the encapsulated chip SIM.
All that it is normally necessary to start the Unit’s operation is to connect the Sensor(s)/Probe(s) to the Transmitter Unit and either fit the batteries or connect the External Power Source.
•Data sent from the iSense devices, via GSM, is collected and stored on the Hanwell Remote Data Service, from where your EMS installation will retrieve it and handle all data presentation and alarm functionality in the normal way.
The Transmitter/Sensor Unit logs data on board and periodically sends this logged data to the Hanwell Remote Data Service at intervals defined by the Send Rate.
•This Send Rate would normally be set to a lower value to save battery power but, in the event of an alarm, the Transmitter/Sensor Unit will switch to a shorter interval between GSM transmissions, if the Send interval configured in EMS is less than 2 hours.
➢If the measurement interval is set to 2 hours or greater, the Transmitter/Sensor Unit will transmit at the normal transmit interval.
•In the event of poor network coverage, the Transmitter/Sensor Unit will retain data packets and retry the GSM transmission in due course.
•The actual, desired, Send Rate (Send Interval), Logging Rate (Internal Logging Interval (Mins)) and Alarm Settings will be sent from EMS when the first signal has been received or when Configuration Settings change.
•Pressing a push button to forces the Unit to take a reading and transmit.
Hanwell applications collect data sent from your iSense Transmitter/Sensor Unit to the Hanwell Remote Data Service by making an outgoing TCP/IP connection to the Hanwell Remote Data Service.
•As this connection is made to a HTTP port 8081 on the Hanwell Remote Data Service, the System operates with the vast majority of network and Firewall configurations.
•A battery life of up to two years for Alkaline and Lithium batteries is possible.
➢These battery life estimates are based on one message a day, 6 measurements daily and no Events enabled.

Your iSense box should contain the following as standard:
•1 x iSense Unit
Plus, additional equipment purchased separately:
•1 x Aerial
1 x Standard knuckle aerial (G205)
1 x Dome/Truck aerial (G455)
1 x Flat blade aerial (AM36913)
•2 x Batteries*:
2 x 1.5V Alkaline C cell battery (88702)
|Note:||Though the Unit can also be powered by 2 x 3.6v Lithium C cell batteries, these cannot be supplied by Ellab due to international transport rules regarding carriage of dangerous goods and must be sourced locally.|
•External Power Supply
➢If you have ordered an External Power Unit, you will be provided with a 12VDC Desktop Power Supply (G422) instead of batteries.
|WARNINGS:||A battery pack must NOT be fitted when the external supply is used.|
The desktop power supply is not rated for outdoor use, if you wish to use this outdoors then enclose the whole power supply in a suitable plastic or fibre glass enclosure
Use only the supplied mains adaptor with these devices.
EMS Software Compatibility
|Note:||Specific Units may require EMS 1.1.0/2.1.0 or later. See individual Transmitter/Sensor Unit specifications listed in the Hanwell Pro Sensor Options Technical Datasheet|
If iSense GSM Transmitters are to form part of a new system, it will be necessary to purchase:
Either: W900 – Standard EMS Software Package
Or: W906 – Validated EMS Software Package
See the EMS Technical Datasheet further options.
The iSense Unit has 4 mounting holes in the back of its case, adjacent to the lid fixing screw holes on each corner; these are accessed by removing the Unit’s lid.
1.Use the four mounting holes in the back of the Unit’s case as a drilling template.
2.Screw the iSense Unit to the wall via the mounting holes.
Hanwell Solutions strongly recommend that the iSense Unit is mounted inside the vehicle body; in any case, the iSense Unit needs to be protected from extreme temperature changes and the force of the wind.
The Unit should be mounted with 4mm diameter bolts, or equivalent self-tapping screws, via the 4 mounting holes in the back of the Unit’s case.
•Where radio reception inside the vehicle is likely to be affected by bodywork etc. use a GSM aerial mounted externally to the vehicle body. See iSense GSM Transmitters Technical Datasheet .
