Output to nutone intercom system

[tandar]

I've connected output 1 from an ElkM1 to the aux input (phono jack) of my nutone whole house intercom. It's wired in parallel with a 25 ohm speaker.

It seems to work fine but I'm not sure if I should be concerned about the impedance. Has anyone wired something similar?

 

Thanks

I see in the link below from ELK. A voltage dropping network of resistors is recommended.

So my previous information was not correct and I removed it.
