How loud are the Model 196 and Model 198 ringers?

What sort of power is required to run the ringers?
The 196 is line powered operating from the ringing current on the central office line.
The Model 198 requires 24vdc and a contact closure.
Can the ringers be used out of doors?
Yes, both ringers are weatherized so they can be used out of doors, but should be protected from direct rain.
(Install under some type of over-hang to provide cover.)
What do the ringers sound like?
A dual modulated tone (very piercing).
How can I get more than one central office line to ring a single ringer?

What’s the maximum number of lines it can be expanded to accommodate?
Can I have more than one person observing different agents at the same time?
The CM-30 & CM-10 will allow up to 4 observers to be observing at the same time, BUT THEY HAVE TO BE OBSERVING THE SAME AGENT. However, you can connect up to 4 CM-30’s or CM-10’s in parallel and have 4 different observers each observing a different individual.
Can I remotely access the Observing Units?
Yes, using a DeesLink Remote Access Unit.
Do I have to use a dedicated phone for the observer’s telephone set?
No, you can tie the Observer’s pair into a vacant C.O. port on the phone system and restrict access to that port to only the observing party.
