Customer has an ATT Merlin Plus. Ext 12 is connected to an SAA unit which is connected to a Wheelock device which is then connected to a loud bell. Problem is that the bell isn't working anymore. I'm going to start by replacing the SAA, then the wheelock device. I can't seem to find a model # on the wheelock and I need to find something comparable. The wheelock device has a turn switch and is labeled 'ON (1)', 'OFF' & ON (2). Any idea what model this could be, I know its pretty old.

let me dig back into my mind.....if im not mistaken you could use a GPA adapter made for the Merlin..........

Matt...go on AVAYA website into documentation, look at the M+ manual....it should have it in there....

i just did this with a customer that needed
a loud bell off of a 10bis
call tqm @1866-876-2500 they had the parts and pre tested them prior to shipment
the alert was a uta-1 and a saa

In my notes I have the Wheelock relay as model number CRT-40. I think that's the relay with the round case.

I did a search on wheelock crt-40 and found nothing. What do you recommend as a replacement. The existing wheelock deice has an modular input from the phone and a modular output that's connecte to a modular input on the bell.

could you use the little viking amp tied to the speaker of the phone?

Unfortunately I'm not familiar with that one (modular). They might not even make the CRT-40 anymore. That had to be wired manually if I recall correctly.

Connecting the speaker leads to an amp is a good idea. I did that with a Rolmphone into a paging amp, but used a 600-600 ohm isolation transformer. A horn speaker would only need about 5 watts or so to be loud.
