Troubleshooting

1)When the doorbell is pressed the phones do not ring, but you can activate and speak to the door station by pressing *1 (or #1 depending on setup).

a.Make sure that you have the correct power supply and that it is supplying 12 VAC.

b.Measure the AC voltage on the “TELCO Output” terminals at the time when the unit should be ringing (just after the doorbell button is pressed). There should be between 70 - 90 VAC across the terminals during a ring cycle.

2)The phones in the house cannot communicate with the door station.

a.Make sure the power supply is plugged in.

b.Make sure the phones are connected to the “TELCO Output” on the telephone entry controller. To be sure of this, connect one phone directly to the “TELCO Output” screw terminals and test the unit.

3)A static or “screeching” noise is heard when speaking to the door station.

a.If DSL is present in the system, install a DSL filter (model P-0411) on the phone line before the telephone entry controller.

4)The TE110DS does not activate.

a. Make sure you’re pressing the correct key sequence.

If already speaking to the door station, just press *71 (or #71).

If not already speaking to the door station, press *1*71 (or #1#71). b. Measure the voltage on the screw terminals labeled “INTERCOM”

When the system is idle, there should be 1 VDC on the terminals.

When speaking to the door station, there should be about 6 VDC on the terminals.

When the TE110DS is activated there should be at least 10 VDC on the terminals.
