Systems Overview

Urmet analogue systems provide answers to all needs and any styles chosen the user for apartment stations and panels

Ideal use for:
Blocks of flats and condos



Audio systems

Audio systems offer the fundamental functions of a system (call, audio and door opening).
There are two installation types: 4+n and 1+n.

4+n
4+n systems have a riser column with 4 common wires plus n wires, where n is the number of calls to be managed. Furthermore, door phones with traditional call (12 Vac buzzer) or electronic call (the speaker of the door phone itself is used to generate the call tone) may be used in 4+n systems. Systems may be created with intercom conversation privacy to the loudspeaking unit. Several automatically switching entrance doors may be catered for.

1+n
The 1+n audio system was created to transform a traditional bell system into a complete door phone system without needing to add wires to the column and ensuring conversation privacy between the various apartments.

Video systems

Analogue video systems derive from the 4+n and 1+n audio systems and may be split into two types: coax systems and 5-wire systems.

Coax video systems
4+n door phones with electronic call are used in coax systems. A very high number of combinations are possible, with both b/w and colour video door phones. The coax cable allows great distances between camera and monitors and allows to create the same system types as a 4+n audio system.

5-wire systems
The 5-wire system derives from the 1+n audio system and is suitable for transforming 4+n audio systems into video systems without adding a coax or other wires in the riser column. The audio/video analogue systems are suitable for small to medium sized installations because one wire is needed in the riser column for each call.

The audio/video analogue systems are suitable for small to medium sized installations because only one wire is needed in the riser column for each call.
