High-tech at the letterbox

Smart supplementary functions

Letterboxes from Siedle can do far more than simply receive the mail. Connection with the door communication system lends the letterbox its own intelligence and creates a uniform look in the entrance area.


Contemporary door communication is about more than just ringing the bell, talking and door release. Demands and expectations in the entrance area have become increasingly complex. Additional disciplines such as information, vision, monitoring, access control, switching and lighting - alongside receiving the post - have all added a new dimension. Letterbox systems from Siedle bring all of these functions together and present them with a uniquely definable style chosen by the user. Alongside aesthetic aspects, there are a whole range of rational arguments in favour of linking door communication and post reception: The electrical, acoustic and ergonomic characteristics of all the components are perfectly coordinated. And there is an ever increasing number of smart functions available for the letterbox - ranging from electrical unlocking to the mail notification system.

Electrical unlocking
For the communication system Steel, Siedle offers electrical letterbox unlocking; this forms an ideal complement to the access control function. It allows the letterbox to be opened by means of fingerprint reader, code lock or electronic key instead of a physical key. For this, the mechanical lock is complemented by the addition of an electrical locking unit, and the letterbox removal door has been given a grip rail. If required, different fingerprints can be read into the system.

"You have mail"
A brief tone, an illuminated symbol, a vibration tone and you know that something has been posted into your mailbox. What we all accept as a normal everyday facility for receiving e-mails and text messages is now also available for your letterbox. Siedle is offering a mail notification system for Classic and Steel. When the letterbox flap opens, a signal is relayed to the user by means of an LED at the deluxe indoor station. When the removal door is opened, the LED is extinguished.
