The following devices, which are not 

among the items supplied, can be con-

nected to the HC450 and operated:
Door opener:

The door can be opened from 

the Gigaset handset or, in the 

case of a forwarded call, from 

a remote location. To do this, a 

standard door opener must be 

connected (not supplied). The 

voltage pulse (12 V alternating 

voltage) for opening the door 

is supplied by the HC450.

Bell:

An existing bell will be con-

nected to the HC450.

Door light:

A light circuit (e.g. the entry 

lighting) can be switched on 

from the handset and if appli-

cable via the bottom bell key 

for between 1 and 90 seconds 

or also operated in pulse mode. 

The connection to the floating 

contact (230 V, 10 A) must be 

undertaken by a qualified elec-

trician.

The illustration below shows the cabling 

with an existing doorbell (before) and the 

cabling following installation of the 

HC450 door intercom and HC450 control 

unit (after).
