POWER, BATTERY, & GROUND WIRING

Power Wiring

✦NOTE: DO NOT APPLY POWER UNTIL THE INSTALLATION IS COMPLETE.

1.Route two wires between the RE-2 and the power transformer.

•For power wire runs up to 100 feet, use 18 AWG, THHN 600-volt insulated wire.

•For power wire runs up to 200 feet, use 16 AWG, THHN 600-volt insulated wire.

2.Connect the wires to the transformer. Connect the other end of the wires to the two RE-2 TRANSFORMER terminals.

Backup Battery

Use of battery backup is optional. It will allow the RE-2 to operate for short periods of time without AC power. Two 12-volt backup batteries in series are recommended to obtain the proper working voltage

for the RE-2. A single 12-volt battery can be used, although the call waiting beeps and the ring voltage will be lower than normal when fi ve telephones are connected. The door or gate access device must use some type of battery backup for the entire system to be functional.

Backup batteries will not fit into the RE-2 housing. Protect the backup batteries inside a rain-tight NEMA enclosure suitable for the installation.

✦NOTE: Backup batteries are not required to maintain the RE-2 clock/ calendar and programming memory during power outages.

1.Route two wires between the RE-2 and the backup batteries.

2.Connect two 1.2 Amp/hour (minimum), 12-volt, gel cell batteries in series (Battery #1 negative to Battery #2 positive).

3.Connect the Battery #1 positive to the RE-2 BATTERY POSITIVE terminal.

4.Connect the Battery #2 negative to the RE-2 BATTERY NEGATIVE terminal.

✦NOTE: The RE-2 does not supply battery charging current. An external battery charger will be required to maintain the batteries.

Earth Ground

For the best ground, use size 12 gauge solid wire or larger to connect to an 8-foot copper ground rod. Locate the ground rod next to the Power and Telephone company rods and bond the rods together with a new clamp. Do not disturb the clamps installed by the Power or Telephone Company. Alternately, connect to a cold water pipe for the earth ground.

1.Connect the wire from the earth ground to the rear case ground stud.

2.Connect the Telephone Bypass Module EARTH GROUND terminal to the earth ground wire.

3.Connect the RE-2EARTH terminal to one of the case ground studs (this connection is mandatory for lightning protection).

Case Ground

A ground wire connects the front and rear cases together. Be sure to re-connect this wire before completing the installation. Refer to Figure 15 for case ground wire attachment details.

OPTIONAL REMOTE ANTENNA

If wireless transmitters are going to be used, a remote antenna must be installed to provide reception for the RE-2.

Two models of antennas are compatible with the RE-2. The Model EXA-1000 is a omni-directional antenna.The Model EXA-2000 is a directional antenna used in installations where transmitted signals are desired to be received only in a particular direction.

✦NOTE: Up to 50 feet of type RG-59 coax can be used to connect the antenna to the RE-2. Keep the coax as short as possible.

1.Install the antenna. (See EXA-1000 or EXA-2000 installation instructions.)

2.Connect the antenna coax cable to the antenna and route the cable to the RE-2.

3.With the power off, connect the cable to the RE-2’s ANTENNA connector.
