SGSK200 WIRELESS SURVEY KIT GENERAL DESCRIPTION The wireless survey kit is a test system for assessing the wireless link quality in the locations of an installation site; it is primarily composed by: a) A dedicated test expander module. b) A wireless probe: this is an assembly composed by two wireless child devices (a detector and a platform sounder). c) A hand held wireless keypad for visual link quality assessment. Specifically, the installer checks the link quality between the test expander module and the wireless probe assembly. Before installation, the test expander is temporarily positioned where a translator or expander module is intended to be permanently installed. Wireless link quality is assessed visually by the installer through the aid of an hand-held keypad, connected, via radio, to the test expander. The installer, by carrying around the wireless keypad and the detector / sounder test assembly, can check whether a certain l ocation is reached or not by an acceptable radio signal coming from the test expander. Through the use of the wireless survey kit it is possible to check if certain locations are suitable for installing translators, expanders and child devices before performing a permanent device installation. In order to make it easier for the installer to check the wireless link quality in locations as high as the ceiling, a pole, to which the test detector / sounder assembly can be attached, is supplied together with the survey kit. Pic. 1 TEST EXPANDER POSITIONING AND POWER UP 1) Place the test expander exactly where the permanent translator or expander is planned to be positioned . 2) The wireless survey kit is supplied with a 12 V power supply unit; plug-in its connector into the test expander’s socket located on the top side; insert the power supply plug into the household’s mains socket (pic. 1). 3) The test expander is now powered up and operative. TEST DETECTOR POWER UP 1) Uninstall the test detector from its test platform sounder. 2) Tear off the battery cover from the bottom side of the detector. 3) Insert the secondary battery into its housing with the positive pole facing up (pic. 2). 4) Insert the primary battery into its housing; battery’s polarity must be correct (pic. 3). 5) By checking the light indicator near the top of the detector, wait the end of the power up sequence.

Wireless link quality is considered acceptable when: DB VALUE IS GREATER OR EQUAL THAN 20 and
ACCEPTABLE
GRADE VALUE IS GREATER OR EQUAL THAN 4.
NOT ACCEPTABLE
IMPORTANT NOTES ON WIRELESS ASSESSING -
Bear well in mind that environmental conditions can influence negatively the wireless link quality; so assess with the environmental “worst case”, with the doors closed, especially when they have a consistent mass and / or made of metal or other material capable of hindering wireless transmission signals.
-
Bear well in mind to that furniture (and other objects) can be moved during the installation’s lifetime, causing variation from the initial assessment; even the presence and movement of people in the installation’s site can generate a variation of the assessed value. Consequently, it is suggested to choose locations having wireless link quality well above the minimum acceptable limits, in order to compensate these variations.
-
Keep an eye on the wireless keypad’s battery level and link quality with the test expander; in need, change the keypad’s battery.
-
After use always power off all the wireless survey kit devices, in order to prolong their battery life.
TROUBLESHOOTING POOR LINK QUALITY If the planned location for the child device has a poor link quality with the test expander, there are three possible solutions: Change the planned location for the child device: using the test assembly find another position for the child device that is planned to be installed; this is the simplest solution, nevertheless there are environmental and normative constraints that have to be taken into account. Change the planned location for the translator or expander; take care if adopting this solution: planned locations that before were reached by a good signal, now, that the translator or expander is shifted, could not be reached by a good wireless signal as before. Change the planned location of the translator or expander, put in that location the test expander and TEST AGAIN the wireless link quality of ALL the locations where its child devices are planned to be installed. Remember to check if the new location of the translator or expander can be reached by a good signal from its parent translator or expander; check, also, that in the new location the translator or expander can reach its child expanders. Plan to add another expander module in the installation system. If this solution is adopted, take care to position the test expander where you intend to place the new expander, and, with the test assembly, check if the location, that before had poor link quality, is now ok. Remember to check if the position of the new expander can be reached by a good signal from its planned parent translator or expander. POWERING OFF THE SYSTEM Wireless keypad 1) Press the On - Off key to power the keypad off.
