Function spectrum
Siedle Steel includes all the functions in the entrance area to provide a perfectly integrated unit in terms of both form and function. The functional scope of each system depends on the requirements and preferences of the individual customer.
Alongside the possible options depicted here, the functional spectrum encompasses letterboxes, inscriptions, surface area lights and an orientation and signage system.

Alarm systems, garage doors, roller blinds – whatever you want to close, key-operated switches do not need to be placed away out of sight. The module accommodates all standard profile half-cylinders.
LED spotlight
The spotlight places emphasis where it is needed, creates accents and outlines contours.
LED light module
Energy-saving and almost indestructible: Four LEDs immerse driveways, paths or the whole entrance area in radiant white light. The modules can be mounted in-row to form large-scale lights.
Status display
The status display provides an optical signal of which function is active. This affords the deaf and hard of hearing clear visual feedback from the intercom.
