Wire Gauge Factoring
1.1 Remote Power Supply
 The Magnalock requires adequate voltage and current for proper operation.
 Resistance is created by the length and gauge (size) of the wire being used.
 An accurate estimated distance from the power supply to the opening is crucial.
 For superior operation the correct size gauge wire must be used.
 The devices used operate the best with the least amount of resistance on the source.
 Using the correct gauge wires protects against large voltage and current (load) losses.
 The gauge is determined by the wire distance, voltage and current of all devices.
1.2 Determining Wire Gauge
 Follow Example A (12VDC system) and Example B (24VDC system) below.
 Use Tables 1 and Table 2 to choose the correct wire gauge for the application.
1.2.1 Example A: (12VDC system)
Devices Used Amps (12VDC) Progressive Totals
M62 Magnalock 0.250 0.250
DK-26 Access 0.160 0.410
XMS Motion 0.050 0.460
EEB2 Timer 0.025 0.485
Total Current Rounded Up (Table 1)
