The VDS system in REPLACEMENT systems
Given its features and resources the VDS system is the ideal system for the replacement of a door entry system with
a video door entry system.
Allows the use of the door entry system’s existing wiring to convert it to a digital video door entry system.
Conventional door entry systems, which generally consist of 4 common wires + 1 call wire per telephone can be
converted to 5 wire Fermax VDS video door entry systems, without the need to replace the existing wiring.
To convert this system to a 5 wire bus, you must connect all the call wires on the entry panel and use them as a
negative wire on the system (see system diagram).
Facilitates systems with up to 199 residences, 2 entrance points and a central guard unit with a maximum distance
of 100 metres. The distance can be extended depending on the system characteristics.
