GEM-P816 Installation InstructionsPage 9NAPCO Security SystemsRINSTALLATIONMOUNTINGControl PanelChoose a mounting location accessible to (a) a continuously-powered AC source, (b) system ground, a steel orcopper ground rod, ideally no further away than 10 feet, and (c) telephone lines (keep telephone wiring away fromkeypad wires). Remove appropriate knockouts for cables. Place the control panel at a convenient viewing heightand mark the mounting holes. Attach the enclosure using screws suitable for the mounting surface.GroundingConnect the control-panel grounding screw to a metal cold-water pipe or a long steel (or copper) ground rod drivendeeply into the earth. Do not use a gas pipe, plastic pipe or AC ground connections. Use at least 16-gauge wire.Make the run as short and direct as possible, without any sharp bends in the wire.KeypadA keypad should be located near each exit/entry door. The keypad features a handy pull-up reference label.Before mounting the keypad onto the wall, push the Sliding Label Plate (with label and felt backing affixed andhandle facing forward) down the guides at the rear of the keypad until it snaps into place. Once installed, theSliding Label Plate cannot be removed without first removing the keypad from the wall. Note: (1) The keypad fireand panic keys should not be considered a substitute for a listed manual initiating device, such as a pull box. (2)Each GEM-RP1CAe2 includes provisions for four additional zones. See ADDING EXPANSION ZONES.If installing onto a double-gang box, insert mounting screws through the two vertical elongated holes on the leftside of the case and into the box. If the box is visible when viewed from the front, adjust the keypad vertically andtighten the screws. Then, using hardware suitable for the mounting surface, add one or two screws at the rightside of the keypad case directly into the wall to ensure a secure installation. Note: Do not overtighten the screws!Uneven walls may cause the keypad case to distort.CAUTION: This equipment generates and uses radio-frequency energy. If not installed using conventional installationpractices for RF devices, it may cause interference to radio and television reception. It has been tested and found tocomply with the limits for a Class A computing device pursuant to Subpart B of Part 15 of FCC Rules, which aredesigned to provide reasonable protection against such interference. However, there is no guarantee thatinterference will not occur in a particular installation. If it has been found to cause interference to radio or televisionreception, which can be determined by removing and reapplying AC and battery power to the equipment, the installershould try to correct the interference by one or more of the following measures: reorient the receiving antenna;connect the power transformer to a different outlet so that the control panel and receiver are on different branchcircuits; relocate the control panel with respect to the receiver.
