2 Master Expansion Kit

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.
• If a door release function is included, use a separate 2-conductor wire from the "EL" terminals of the masters, through an AC transformer, and to the door strike.
• The door release button on the master station is a Normally Open (N/O) contact closure.
