CHECK for voltage from Magnalock to door
frame; there should be no voltage present.
DETERMINING WIRE GAUGE
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 optimally 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. CALCULATE total current for either a 12 VDC system (see Table 1, “12 VDC
System”) or a 24 VDC system (see Table 2, “24 VDC System), as required.
