Q - Are the 5-Channel Radio Doorbell Intercoms (Models WHDBI-5C and WHI-5S) compatible with the line-carrier Westinghouse models?
A - No, model WHDBI-5C and WHI-5S are compatible with each other only.

Q - Can I monitor more than one room at a time?
A - No, only one room can be monitored at a time. This unit will be placed in the "lock" position.

Q - The red light is on; I cannot communicate with the other units?
A - Another unit may be in the lock position. The intercoms cannot communicate if one is being used to monitor a room.

Q - The power light is on yet I cannot get the intercom to work, what am I doing wrong?
A - These intercoms must be plugged directly into the electrical outlet. Power strips, surge protectors or filters cannot be used.

Q - How do these units work, will they work from one house to another?
A - The intercoms are "line carriers" meaning they send an FM signal through the electrical wiring. In order for the units to communicate, they must be on the same "leg" or phase of electricity. They are not designed to work from one building to another.

Q - How many intercoms can be added on?
A - The Westinghouse intercoms can have as many units as desired. However, if "private" channels are needed, only three or four units respectively can be used. "Private" channels are when each unit is dedicated to only one person/location. Only the intercom units on that channel will be able to communicate.

Q - Can 2 channel systems be expanded?
A - The 2 channel system can be expanded with additional pairs of 2 channel intercoms or by adding single unit 3 or 4 channel units.

A - The WHDB-301 can be used with our 2, 3, and 4 channel intercoms.

Q - Why does the Doorbell Intercom System not come with a 2-conductor wire?
A - The two conductor wiring (like speaker wire) is not included due to the varying lengths needed in different installations.

Q - What is a 2-conductor wire?
A - Two conductor wire is simply two wires run together from one point to another, like speaker wire.

Q - The term line carrier means?
