I am wondering if I can use both 2 Wire 70V paging and 4 Wire 24 V Valcom

By sharing the same output

Customer wants to add additional paging horns to the outside of each building

I am a little concerned about possibly overloading TOA 724 Amplifier

So I was thinking of just using Valcom 24 v paging horns

Just for outside

any thoughts

Thanks
