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 11.
5.  Secure and lock the AM-KP to its mounting plate.
