## Questions & Answers

**Q: How do you adjust the volume on the buzzer?**
A: There is no “buzzer” alert for this unit..  It’s called a “call tone”.  The “buzzer” is at the electric strike on the door for the release of the lock and not part of this intercom unit.  What the question likely refers to is the “call tone”.  The adjustment for the call tone volume is a switch on the underside of the cover.  The cover must be removed to access it.  This is mentioned on the online documents specifically in the LED-1DLS Spec Sheet.  You would think they would mention it in the install manual instruction sheet.  They don’t even point out there is a switch inside.

**Q: can you use 2 masters (in seperate rooms ) with 1 door intercom ??**
A: Yes, that is what we did at our church.

**Q: Can this be used with battery**
A: Yes, input states "12 Volts, AC/DC"  I used a small 12 Volt battery until I got the system completely installed.  Worked fine.

**Q: I have a 16v nutone door station (doorbell/speaker/microphone) already installed. is there any reason the lem-1dl wouldn't work with it?**
A: This unit is compatible with specific door stations. Would need to check model number on yours to see if is compatible.
