## Questions & Answers

**Q: Can this be used with the Urmet BiBus system?**
A: Was cheap and easy to install, I think the one it replaced was urmet tho. Hope this helps

**Q: How does the ringing work? Is there a built in speaker to alert when someone rings bell?**
A: Yes there is a buzzer, I believe it uses the handset speaker as there is nothing in the body of the unit.

Mine is plenty loud enough, I replaced an old handset as it wasn’t alerting me

**Q: Does this have a volume control?**
A: Sorry zi don’t know as I am unable to make mine work due to some incompatibility with my old system.
