So I didn't do my homework before I sold and application. I installed an analog board in the MP5000 to support standard 2554 wall phones. And I wanted to put a strobe light above each phone to help alert the workers when a particular phone was ringing. Hooked up the phone and strobe together on the same port (Wheelock PS15A-WPW)and the phone will ring but the strobe will not light. Anyone have another solution?

Specs say it's only 1.5 Ren so it should work, I'd think. Will it work without the phone? Check your voltage output it says 50 to 130 volts which is a pretty wide range.

I don't have the specs in front of me but some of those Wheelocks required an auvillary power supply for the Strobe and line voltage rang the phone and signalled the lamp. See if that model is one of those.

The one he listed didn't RBF. Just suppose to work off line voltage.

You da' man. I was too lazy to go looking. It's Friday.

Don't know the MP5000, but a lot of new switches are 24 volt DT, not 48 volt, as the ringers/strobes expect. That means it will do one or the other, not both, per port. This is common on the newer switches.

I use a 115 volt strobe/horn combo for that type of situation. No need for the ringer on the phone.

Just my $.02

Many of the line powered telestobe products will not work reliably behind a pbx. The charge discharge of the strobe network is too slow. The same device will however, work perfectly on straight line voltage.
