They both measure 110dba @ 1 meter (at maximum volume). What sort of power is required to run the ringers? The 196 is line-powered, operating from the ringing current on a POTS (Plain Old Telephone System) central office line. The Model 198 requires 24 Vdc and a contact closure. Can the ringers be used outdoors? 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.) Can the volume be adjusted on the ringers? Yes, the 196 has a three position switch (low, med, high). The 198 has a continuous adjust volume control (fully off to maximum volume). What do the ringers sound like? A dual modulated tone (very piercing). There’s a low-volume sample on our Stinger 90 webpage. How can I have multiple central office lines ring a single loud ringer? The Model 173W lets three C.O. lines ring one common ringer (196 or 198/PSU). Multiple 173Ws can be daisy-chained to support even more lines. What is the ringer equivalency number for the 196? 2.7 B [ BACK TO TOP ] Service Observing, Call Monitoring How many lines can the CM-30 observe? 30 lines. What’s the maximum number of lines it can be expanded to accommodate? 90 lines. 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. How do the CMs connect? Their inputs tie down in a parallel arrangement over the Tip and Ring leads of the agents you want the ability to observe.

In fact, the 154 can be used as ground-start converter for loop-start office machines. What are the power requirements? The Model 154A-8/PSU includes a -24Vdc plug-in supply. The Model 154-8 requires -48Vdc, obtained from your PABX or our PS-4800. [ BACK TO TOP ] Meridian Digital Centrex Products How do I connect a loud ringer to my Meridian Business Set? The DSI-375 is a Custom Ringer which allows for connecting an additional loud ringer, i.e. Model 198 to the MDC line. Can I record from a MDC line? Yes, the CRI-376 is a recording interface adapter that allows a selected line appearance on your Meridian Business Set to be interfaced to a recorder.
