Loudspeaker Paging- Cheap Alternative Found?

[samhuangavaya]

Hi all,

I wanted to get some feedback on getting one (or 2... or 3) horn(s)/loudspeaker(s) for an Avaya Partner System. We have all 18D phones, 2+ of which are in a loud shop location where it's often hard to hear the rings. I thought that we could maybe wire in a horn to it to make it louder, without an amplifier. Could we also possibly use the horn for paging?
I know of a wood shop with an (fairly- 8+yrs?) old Nortel(?) PBX System that didn't ring very loudly. They brought a horn and wired it (I think) into the phone and connected it to the speakers. I knew that because "speakerphone" would come over the loud horn. The ring was significantly louder and could be heard better because of a better horn placement. It worked great on this phone system with over 300 extensions.
I know I can open up one of my Avaya phones and wire the horn in, but I didn't know if it would be a good idea with this particular Avaya phone system- a 30+ watt horn might put extra strain on the phone and the system which could cause a headache that I don't need.

So, any feedback? Has any of you done this before? Success, Failure?
Let me know- I don't want to be frying any systems!

Here's the horn I'm looking at...

Um, no. That is a SIREN horn. Not what you want.

You want a self-amplified horn, along with an appropriate power supply.
Something like a Valcom V-1030C

No strain on the phone or system, but every time you access the speaker of the phone, it will broadcast all over the shop.

Otherwise, something like a Bogen TPU-15A amplifier, some 70V horns, connect to the Page Port on the ACS, and use a spare station to trip the "night" ring built into the amplifier.

Hi TTT,

Please clarify on a Siren Horn- what does this mean? No one would be using the speaker in this loud environment anyways (pretty much impossible to hear anything), so the speaker phone broadcasting over the shop would be ok.

So I guess wiring a un-self-amplified speaker on the horn would work? Is there a reason to use the Valcom Amplified one if the regular one works? I suppose it won't be as loud but...

PS... I found this- seems to look good. Now I think I actually saw an Valcom horn one in that wood shop.....

The horn in your first post is for an alarm system, not a paging system. Apply 6 to 12 volts DC and you've got a 120dB banshee. Fine for scaring away burglars, but not for paging and loud ringing off of a phone set.

You can't just put a larger speaker on the Partner phone, it won't drive it. You need to amplify the signal. The Valcom horn you found in your 2nd post is fine, but you also need a 24 volt DC, 300mA power supply.

Hi Tommy-

One last question I just thought of. If we can wire in any amplified Valcom horn, wouldn't it be possible to wire in any pair of speakers? (e.g. 3.5mm computer speakers, etc?

Thanks,
Sam

If they're powered, sure, why not?
