Overview The wireless nodes are based on direct‐sequence spread spectrum (DSSS) communication in the 2.4 ‐ 2.5GHz band, compliant with IEEE 802.15.4‐2006. All nodes have a unique MAC address, equivalent to a unique serial number. All devices have an on/off switch. All nodes retain their configuration properties across a power failure. Environmental • • • • Storage temperature range of ‐10 to +80°C Storage relative humidity range of 0 to 90% (non‐condensing).
SSK Functional Overview The Sontay® SonNet Site Survey Kit (SSK) is designed to make the design and installation of a SonNet radio sensor system simple and quick and to take the guesswork out of the radio communications aspect of the network. The SSK receiver should be placed where the actual RF‐RX system receiver will be installed (typically in a plant room or riser).
Verification Mode Verification mode is a special mode that an SSK node or router can adopt specifically to test the LQI to another device. In this special mode, the device ignores the normal hierarchical rules used to form a robust network, and relies solely on signal strength. When a device is requested to go into verification mode, it will briefly drop off the radio network and, having rebooted, reappear running in verification mode.
Battery Fitting and Replacement When a battery is first installed, or when it is replaced, observing the correct polarity is very important. Fitting the battery incorrectly may result in permanent damage to the sensor. Recommended batteries are: Nodes and routers: 3.7V Lithium Polymer, rechargeable 1080mAh (Uniross U0110952) Hand Held Monitor (HHM): 3.
SSK Nodes RF‐TS‐900 nodes are used in conjunction with the Sontay® RF‐RXSS receiver, RF‐PS‐500 routers and RF‐HHT hand held monitor. Data is transmitted back to the receiver every 30 seconds. Each sensor retains these configurations if the battery becomes discharged or requires replacement. NB ‐ To preserve battery life, an SSK node will automatically go off‐line after approximately 4 hours if not power‐cycled.
RF‐PS‐500 SSK routers are used in conjunction with the Sontay® RF‐RXSS receiver, RF‐TS‐900 nodes and RF‐ HHT hand held monitor, and are used to route signals from battery powered nodes and other routers to the receiver module, where the signal strength of a direct path is not sufficient for reliable communications.
The SSK Receiver The Sontay® RF‐RXSS receiver collects data from all other devices on the SSK radio network, including measurements from sensors, link quality for all links formed in the network, battery levels for all battery powered devices, hours run for all devices and the current status of all devices. NB There are no analogue outputs on an RF‐RXSS. The SSK receiver is used solely to determine signal strengths and whether routers need to be added to a network to achieve complete, reliable coverage.
The SSK Hand Held Monitor The Sontay® RF‐HHT displays all on‐line receivers, routers and nodes in the SSK radio network, and shows link quality for all links formed in the network, battery levels for all battery powered devices, hours run for all devices and the current status of all devices. To switch on the HHM, press and hold the OK key for approximately 1 second. To switch off, press and hold the OK key for at least 2 seconds. The HHM will beep to indicate that it is shutting down.

The Radio System The radio system used by the Sontay SonNet devices is divided into 3 sections or ‘layers’. 1. 2. 3. The radio layer is where physical control of the radio signal is done. This conforms to international standard 802.15.4, and determines the frequency of the radio signals, the number of ‘channels’ available for use, the bandwidth and power level of the signal etc. There are 16 channels available, and the best one is automatically selected by the receiver.

FAQs a. How is access to the sensor network locked at the CMS? Nodes are only allowed to join the network if the receiver allows them to. This is true even if the nodes are identified as SonNet Nodes and have the correct encryption key. There are two methods to configuring the receiver to accept nodes on to the network. In order to authorise a node the CMS must be in administration mode (File‐>Switch Admin Mode must be ticked).

Conducting a Site Survey: A Step‐By‐Step Guide 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Ensure all SSK device batteries in the SSK kit are fully charged. Place the SSK receiver where the system receiver will finally be installed. NB ‐ it is extremely important that if the system receiver is to be mounted in an enclosed panel (metal or plastic) so that an external aerial extension is used, an SSK receiver extension aerial must be used and placed where the system receiver aerial will be finally be installed.
f. In the HHM display, where a listed device is a router, to the right of that device will be a number which denotes the number of “children” the router has. g. Using the HHM, observe the link quality for the new router to the receiver. If the link is shown as good, proceed to step 11h. If the link quality is shown as marginal, select the new router and then navigate to “Verification” on the HHM menu. Press the OK key to force the new router into verification mode.
Best Practise Points: 1. Always conduct a site survey, and ensure that if you plan to use an external extension aerial on the system receiver (for example, if the receiver is to be in a metal panel), you use the same external extension aerial on the SSK receiver for the survey. Document the survey thoroughly, and leave a copy on site. 2. When planning where routers are going to be needed, plan for “redundancy”, i.e.
