POWER, BATTERY, & GROUND WIRING
Power Wiring
✦ NOTE: DO NOT APPLY POWER UNTIL THE INSTALLATION IS
COMPLETE.
1. Route two wires between the RE-1 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-1 TRANSFORMER terminals.
Backup Battery
Use of battery backup is optional. It will allow the RE-1 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-1. 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 fi t into the RE-1 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-1 clock/
calendar and programming memory during power outages.
1. Route two wires between the RE-1 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-1 BATTERY POSITIVE
terminal.
4. Connect the Battery #2 negative to the RE-1 BATTERY NEGATIVE
terminal.
✦ NOTE: The RE-1 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 the 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 RE-1 EARTH terminal to the earth ground wire.
2. Connect the Telephone Bypass Module EARTH GROUND terminal to
the earth ground wire.
OPTIONAL REMOTE KEYPAD
The optional Model AM-KP remote keypad can be used with the
RE-1 entry system. A typical application for the remote keypad
would be to control a second door or gate. Entry codes are the only
method of access allowed at a remote keypad. The default system
setting will cause the remote keypad to activate Relay #2.
1. Mount the AM-KP keypad onto a pedestal or to a wall.
2. Route 6-conductor cable from the RE-1 to the AM-KP.
• For wire runs up to 300 feet use 24 AWG Belden Type 9931 or
equivalent.
• For wire runs up to 600 feet use 20 AWG Weico Type 9405 or
equivalent.
3. Set the DEVICE ADDRESS rotary switch in the AM-KP to match the
remote keypad address in the RE-1 (default = 3).
4. Connect the 6-conductor cable as shown in Figure 17.
5. Secure and lock the AM-KP to its mounting plate.
