Stainless steel back plate 16.
WALL MOUNTING INSTRUCTIONS Remove the front plate from the plastic enclosure. Unscrew the back plate from the enclosure. Screw the back plate to the wall. It is recommended that an 8mm nail in anchors be used. Bring 220v AC cabling in through the middle hole. Once the back plate is securely in place, screw the plastic enclosure to the back plate, feeding the cable though the middle hole, with the 4 mounting screws provided. Replace the front plate.
PCB LAYOUT DIAGRAM
HOW TO WIRE YOUR SYSTEM The MKII unit is supplied with some wiring in place. Before wiring the unit ensure that the Battery is unplugged and that the 220V mains supply is not powered. Refer to the PCB diagram. RELAYS and INPUTS (Defaults) 1. 2. 3. 4.
POWER 1. Wire the 220VAC mains to the lightning protection unit, observe the earth and polarity. Apply the mains power. 2. Connect the battery to the battery connector. SYSTEM CHECKS The MKII will now boot up and after about 1 minute is ready to operate. Make sure the installation is good by checking the following: GSM signal: type *#0002. The signal should be between 17 and 31. If not you may need a better GSM antenna or the GSM antenna wiring is faulty. Try to re-orientate the Antenna.
• The maximum GSM cable length should not exceed 10m, and should be kept as short as possible. Longer runs will require the use of higher gain antennae • The GSM antenna can be extended from its standard length with a Combapproved RF cable extensions. This will ensure proper RF impedance matching and signal quality. Do not extend the GSM antenna by joining cables with soldered • High Gain GSM antenna may be used to boost the signal strength.
