Wiring Two Alternate Action Switches to Control a Single Load

Introduction

This article provides instructions on how to wire two alternate action switches, such as Mortise Keyswitches, to control a single load. This configuration is commonly used in security systems to control door locks or other devices.

Components Required

• Two MKA Mortise Keyswitches
• Magnalock M62B or M32FB
• DK-26 Digital Keypad
• DK-11 Key Switch
• MKAN Power Supply
• BPS Power Supply
• 18g stranded wire

Wiring Diagram

The following wiring diagram shows how to connect the components:

Wiring Instructions

1. Connect the positive terminal of the M62B or M32FB to the positive terminal of the MKAN Power Supply.
2. Connect the negative terminal of the M62B or M32FB to the negative terminal of the MKAN Power Supply.
3. Connect the positive terminal of the DK-26 Digital Keypad to the positive terminal of the MKAN Power Supply.
4. Connect the negative terminal of the DK-26 Digital Keypad to the negative terminal of the MKAN Power Supply.
5. Connect the positive terminal of the DK-11 Key Switch to the positive terminal of the MKAN Power Supply.
6. Connect the negative terminal of the DK-11 Key Switch to the negative terminal of the MKAN Power Supply.
7. Connect the positive terminal of the MKA Mortise Keyswitch 1 to the positive terminal of the DK-26 Digital Keypad.
8. Connect the negative terminal of the MKA Mortise Keyswitch 1 to the negative terminal of the DK-26 Digital Keypad.
9. Connect the positive terminal of the MKA Mortise Keyswitch 2 to the positive terminal of the DK-11 Key Switch.
10. Connect the negative terminal of the MKA Mortise Keyswitch 2 to the negative terminal of the DK-11 Key Switch.
11. Connect the positive terminal of the BPS Power Supply to the positive terminal of the M62B or M32FB.
12. Connect the negative terminal of the BPS Power Supply to the negative terminal of the M62B or M32FB.

Testing the System

Once the wiring is complete, test the system by turning the MKA Mortise Keyswitches in both directions. The Magnalock should lock and unlock accordingly.

Troubleshooting

If the system is not working properly, check the following:

• Make sure that all connections are secure.
• Check the polarity of the power supply connections.
• Check the settings of the DK-26 Digital Keypad and DK-11 Key Switch.

Conclusion

By following these instructions, you can successfully wire two alternate action switches to control a single load. This configuration is commonly used in security systems to control door locks or other devices.
