Re: Hook in AC Fire Alarms to Security System

["Crash Gordon" <webmaster@xxxxxxxxxxxxxxxxxxxxx>]

ONe question would be; do line carrier devices transmit anything if the ac
sine wave is non-existant? I'm *guessing* - not.

| off or is there intelligence in it to only trigger for an event which
| is long enough?
|

| wireless zones I'm not using anyway on my panel.
|
| Thanks again!!!
