Step-by-step guide

1. If looking to apply power (complete the circuit):
2. NO of the DS150 to the Positive of the Maglock.
3. From the negative of the Maglock to the negative of the power supply.
4. From the Positive of the power supply to Common on the DS150.

1. If looking to remove power (break the circuit):
2. NC of the DS150 to the Positive of the Maglock.
3. From the negative of the Maglock to the negative of the power supply.
4. From the Positive of the power supply to Common on the DS150.

Generally we do fail safe not fail secure and the relay timer needs to be incremented.
