The new European Standard for vibration detectors, EN50131-2-8, mandates stringent performance criteria across a wide range of surface materials. The Impaq S Series exceeds these requirements, and has been independently certified to Grade 2 by Kiwa Telefication. Open the device cover and remove the PCB using a screwdriver. Fix the base onto the mounting surface. To comply with EN50131-2-8, move DIP switch “S” to the ON position. Select an empty zone slot for the device and put the system into learn mode. To power up press and hold the sensitivity button for 3 seconds. Within 10 minutes of learning the device (or by activating walk test mode), double press the sensitivity button and the LED will flash blue defaulting to sensitivity setting 2. Before testing the device, press and hold the button (3 secs) to set the desired sensitivity setting. The LED will turn green for confirmation at which point the device is ready for impact testing. On impact test, if the LED turns red, the selected sensitivity setting is appropriate for the installation. Magnet positioning. To comply with EN50131-2-6, move DIP switch “M” to the ON position. The magnet can be installed on either side of the device. However, greater sensitivity is achieved by placing the magnet at the bottom right of the device and aligning the notch and the arrow. If the device LED pulses red, move the magnet closer to the device until the LED turns green.
