V. Frequently Asked Questions
1. If I have more than one EC-8 can I connect them to the same phone line
either in parallel or in series (using a “daisy chain”)? Each EC-8 Consolidator
requires its own phone line or local phone. (Exception: A 2-line local phone,
connected to the LOCAL port will allow 2 EC-8’s to be connected in parallel.)
2. What kind of cable do I need to run from the Emergency Phones to my EC-8
Consolidator? We strongly recommend twisted, shielded pairs with the shield
connected to earth ground only at the EC-8 end. The resistance on the line is
not to exceed 25 ohms. The following chart shows distances and recommended
wire gauges:

3. I am using an EC-8 Consolidator in “local” mode. Do I need to program a
phone number into my Emergency Phones? You must enter a phone number
(see Emergency/Information Phone Manual, page 8) even though your Talk-A-
Phone unit is not using this number to connect to the local phone. We
recommend the number 1234567.
4. If I made some mistakes during programming is there a way to reset the
programming? If you have forgotten your access code, you may reset the
programming on your EC-8 to factory default by entering *30*14725836*. Note:
you will NOT have to reprogram your individual Emergency/Information
Phones.
