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.
