5.3 ELECTRICAL INSTALLATION
5.3.1
General Characteristics
The Magnalock is a low current load device using specialized internal circuitry. The normal
characteristic of an inductive load, such as inductive kick-back, is not present. See Section 2 for
more information.
5.3.2
Electrical Standards
DC voltage, full-wave rectified, must be provided for proper operation of the Magnalocks. The
red wire receives +12VDC or +24VDC, and the black wire, 0 Volts (negative). If the lock is
connected with reverse polarity, it will not operate. The M32, M62 and M82B Magnalocks are
auto sensing dual voltage locks. The Magnalock circuit design will automatically select the proper
operational conditions for the applied voltage. See Section 2 for more information.
5.3.3
Poor Release Characteristics
The Magnalock is designed with quick release circuitry. Wiring errors may cause a Magnalock to
release slowly. Figure 10 illustrates a parallel installation of a resistive load (correct). Figure
11 illustrates a parallel reverse diode (incorrect).

5.3.4 Sensor Ranges (ELECTRICAL)
The “B” version monitoring system is also voltage sensitive. The specified voltage ranges must
be properly applied. Refer to Section 2 for the recommended operating voltage ranges.
