This product is useful if you have an intercom system where you have to press a button to let people into your building before they can get to your front door.
This situation commonly occurs in flats that require a code before you can access the building.
This transmitter is an accessory to the Libra+ doorchime (Product code A231) so it won't work on its own.
How does it work?
It has a little microphone that attaches to the intercom speaker and when someone presses the intercom buzzer it sends a signal to the Libra+ doorchime. This makes the Libra+ flash and send out a loud audible alarm to alert you. The alarm will sound different to the one you hear when someone is at your front door so you can differentiate between people pressing the intercom and neighbours pressing your doorbell. In addition the Libra+ doorchime will light up a different icon to add extra clarification.
- Ideal for people who have to 'buzz visitors up' before they can get to their front door.
- Works as an accessory to the Libra+ doorchime system
