Description

DoorLine door stations, the clever alternative to the classic door intercom

Key Features

Expansion module for the DoorLine TM4, Slim/Slim DECT and Pro Exclusive; the switch box is connected via 5 wires that are connected directly to the DoorLine

Improved burglary protection: SwitchBox communicates with DoorLine via security protocol, so that bridging the door opener contacts is not possible

Extension of switching contacts: if the number of switching contacts of the existing DoorLine is not sufficient, they can be extended by 3 additional closing contacts with the SwitchBox; additional door chimes or openers controlled via the house phone are possible

The use of a SwitchBox allows you to connect a DoorLine Pro Exclusive to up to 4 TK systems/routers and a DoorLine Slim to up to 2 TK systems/routers
