Siedle Steel function modules

The loudspeaker and microphone form the basis of every intercom system. Siedle offers perfect voice quality, even in noisy environments.

Light and call buttons in backlit plastic, made of solid metal with laser lettering or engraving – filled in black on request.

The alternative to standard buttons. Made from the solid metal of the front panel, these are clearly identifiable and easy to use.

Scroll and tap – with Siedle Touch, it really is that easy to dial. These displays are available with a large 10-inch or a practical 5-inch screen.

With its large horizontal field of view of 175°, the camera 180 covers almost the entire entrance area, thereby offering maximum security.

Made from the front panel material, solid, brushed or coated surface.

The contrasting mounting level becomes visible through the lasered cutouts in the solid front panel.

Opens the door or serves as a control centre for everything with a switching function. If combined with a user list in the info module, the code lock also works as a call system.
Siedle Steel letterboxes

The post falls into a shaft and is removed from within the building. The pass-through flap is made of the front panel material. The flap closes softly, so you can say goodbye to irritating rattling!

The free standing pedestal with receipt of post is typical and true to form for Siedle Steel: The letterbox housing with front removal only protrudes as much as required to do its job.

Siedle letterboxes do much more than just hold post: They offer damp and removal protection, a mail notification system, electrical unlocking, a delivery box for parcels and much more.
Always perfectly powered – line rectifiers from Siedle
Siedle’s intercom systems are as individual as their power requirements. And these are covered by our line rectifiers. Nowadays, new systems are installed in the In-Home bus, so we specifically focus on line rectifiers for this installation technology. You can find an overview of the line rectifiers for the 1+n and 6+n intercom systems as well as for our Siedle Access Professional IP system here .
Our partners in electrical planning and installation will advise you on the right power supply and the corresponding Siedle line rectifiers.

This extremely cost-effective device is standard in the In-Home bus. It supplies audio and video users as well as the door release and nameplate lighting. It is designed for up to eight residential units.

In the classic door intercom system, the Siedle bus line rectifier supplies and controls the door release, nameplate lighting and up to 31 audio users per line. You can have up to 15 lines.

In new and existing systems, our bus video line rectifier serves up to 31 audio and video users per line; with 15 possible lines. An optional video amplifier can be plugged in.

The NG 706 line rectifier supplies additional components and functions, the PSM 1 12 24 supplies individual IQ in-house telephones and bus video panels and the TR 603-0 transformer supplies the door release and nameplate lighting.

Communication and signage system
We have developed a communication and signage system which combines the unlimited variety of the high-end Siedle Steel communication system with an ergonomically optimised signage system. The result is a perfect welcome – consistent and uniform throughout the entire building.
There’s more to the perfect welcome than the entrance alone. Visitors are initially greeted by a parking sign or the garage entrance and make their way to a specific room. Different functions are important at each stage along this route: Identification of the building and its occupants, interaction with the host, internal access and finally guidance to the destination.
