INSTALLATION
MOUNTING
Control Panel
Choose a mounting location accessible to (a) a continuously-powered AC source, (b) system ground, a steel or copper
ground rod, ideally no further away than 10 feet, and (c) telephone lines (keep telephone wiring away from keypad
wires). Remove appropriate knockouts for cables. Place the control panel at a convenient viewing height and mark
the mounting holes. Attach the enclosure using screws suitable for the mounting surface.
Grounding
Connect the control-panel grounding screw to a metal cold-water pipe or a long steel (or copper) ground rod driven
deeply 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.
Keypad
A 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 and handle facing
forward) down the guides at the rear of the keypad until it snaps into place. Once installed, the Sliding Label Plate
cannot be removed without first removing the keypad from the wall. Note: (1) The keypad fire and 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 left side of
the case and into the box. If the box is visible when viewed from the front, adjust the keypad vertically and tighten the
screws. Then, using hardware suitable for the mounting surface, add one or two screws at the right side 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 installation
practices for RF devices, it may cause interference to radio and television reception. It has been tested and found to
comply with the limits for a Class A computing device pursuant to Subpart B of Part 15 of FCC Rules, which are
designed to provide reasonable protection against such interference. However, there is no guarantee that
interference will not occur in a particular installation. If it has been found to cause interference to radio or television
reception, which can be determined by removing and reapplying AC and battery power to the equipment, the installer
should 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 branch
circuits; relocate the control panel with respect to the receiver.
