u Label the enclosed nameplates using a 

waterproof pen. Insert them in the 

recesses in the doorbell keys.

u Position the doorbell key cover on the 

doorbell key from above and then 

apply gentle pressure at the top 

and bottom.

u Replacing nameplates: Insert a small 

screwdriver at an angle in the narrow 

notch on either side of the doorbell key 

cover. Carefully lever off the cover. 

Remove the nameplate.

The following requirements for mounting 

must be fulfilled:
u The HC450 control unit contains a 

DECT radio module. This module must 

be mounted within the base station's 

radio range (typically around 30 m 

indoors). Check the range using the 

handset before fixing the control unit. 

If a connection from a DECT handset to 

the DECT base station is possible at the 

designated location (field strength dis-

play shows at least one bar or a call of 

long duration is possible with satisfac-

tory quality), you can mount the con-

trol unit here. If there is no connection 

to the base station at the designated 

mounting location, the range can be 

extended by means of a repeater 

placed between the base station 

and control unit.

u Mount the HC450 control unit at a suit-

able location along the junction wire 

between the bell button and bell. 
It is recommended that you mount the 

unit near the bell transformer. This is 

normally located in the fuse box. Any 

adjustment required to the fuse box 

must be undertaken by a qualified 

electrician.

u To ensure that a suitable mounting 

location is selected, familiarise yourself 

with the location of the cabling before-

hand. Watch out for the cabling 

between the bell button, the bell trans-

former and the bell. Lay the cables so 

that nobody can walk on or trip over 

them. Before finally mounting the 

control unit, check the placement of 

the unit with temporary cabling by per-

forming a function test (control unit 

can register with the base station, sta-

ble operation possible with adequate 

connection quality from the handset to 

the HC450 door intercom). 

u You should also refer to the mounting 

instructions for the HC450 door inter-

u The control unit must not be installed 

in a fuse box or metal housing.

u The control unit must not be installed 

near air conditioning systems, in areas 

with strong sunlight or in dusty 

environments.

u The control unit must be protected 

from the direct influence of water 

and chemicals.

u Areas with strong magnetic fields 

(transformers, electric motors, high-

voltage lines) must be avoided.

u Cables must not be connected or dis-

connected or the HC450 control unit 

installed during a thunderstorm.

u Watch out for electrical, water or gas 

lines in the wall if mounting the control 

unit on the wall.

Remove the terminal cap before mount-

ing. Apply firm pressure to the terminal 

cap with both thumbs and slide it in the 

direction of the arrow.
