If you need a very basic indoor wired intercom system, this 3-Call Master Station and 1 Substation kit may be what you need.
This kit consists of one Master station, one Substation, and one power supply. You can add up to two more Substations and the Master station has three buttons that can be used to call each Substation individually.
If you want to monitor the area around a Substation, you simply press the button on the Master that corresponds to the Substation you want to monitor. To stop monitoring you simply press the Off button. While the Master is in monitor mode, other Substations cannot audibly call the Master, but an LED lights above the corresponding Substation switch on the Master for a period of 20 seconds.
Each Substation can call the Master by pressing the Call button. A tone will sound as long as the Call button is pressed. Once the Master responds, the Substation can then talk hands free and the Master station operator will need to press the Talk button to reply.
The Master calls a Substation by pressing the corresponding Substation button and then pressing the Call button to sound a ring tone. The Master does not have to wait for a reply and can simply press the Talk button to speak.
Substations cannot communicate with each other.
Only two conductor wiring is needed from a Substation to the Master. Substations cannot share a wire with each other.
You can add two more indoor or outdoor substations to this system. See Related Products and Accessories to order these substations.
