PART 3 WIRING THE UNIT
A. MAIN PROCESSOR BOARD CONNECTIONS
Figure 4. Main Processor Board Connections.
CAUTION
Do not apply power to the unit until all other connections have been made.
Damage to the unit may otherwise result.
1. GROUND THE CABINET in accordance with local code to a good earth/cold water ground
nearby. The chassis ground lug is located on the lower left-hand corner of the Main Processor
Board, as shown in Figure 4.
2. GATE/DOOR
CONTROLS: Connect the wires from your gate operator or door strike and door
strike power supply to TB1 as follows:
a.
Dry Contact Closures (most gate operators):
Relay 1: connect conductors to "NO1" and "COM1" terminals.
Relay 2: connect conductors to “NO2” and “COM2” terminals.
b.
Normally Locked Strikes:
Relay 1: connect one conductor from your strike power supply to "NO1" and one
conductor from the door strike to "COM1", then connect the remaining conductors from the
power source and strike off of the board using a wire nut or butt splice.
Relay 2: connect one conductor from your strike power supply to “NO2” and one
conductor from the door strike to COM2”, then connect the remaining conductors from the
source and strike off of the board using a wire nut or butt splice.
c.
Magnetic or Normally Open Strikes:
Relay 1, connect one conductor from your power source to the "NC1" terminal and one
conductor from the door strike to the "COM1" terminal. Then, connect the remaining conductors
from the power source and the strike by tying them together using a wire nut or butt splice.
For relay 2, connect one conductor from your power to the “NC2” terminal and one
conductor from the door strike to the “COM2” terminal. Then, connect the remaining conductors
from the source and the strike by tying them together using a wire nut or butt splice.
