This expansion kit allows you to add up to two additional master stations to your Single Door Access System (1 Door Station, 2 Masters). The kit includes all necessary components, including a power supply, ensuring seamless integration.
Note: A maximum of two of these kits can be added to your system.
Operation Notes
- Only one master station can be active at a time.
- If both master stations are activated simultaneously, audio feedback (squealing) will occur when either TALK button is pressed.
- To eliminate feedback, press the OFF button on one of the master stations.
Installation Guidelines
- Use 2-conductor shielded wire from the door station to the first master, then continue to the additional masters.

- The door release button on the master station is a Normally Open (N/O) contact closure.
