generator is attached is pressed, the signal generator is activated for
approx. 3 seconds.
The door intercom DVT50T2 has only one wired output for a signal
generator. This output is assigned to the upper doorbell button, i.e. the

activated for the time set on the mobile unit.
15. Tamper alarm

has batteries fitted is removed from the protective cover, a pulsating
tamper alarm sounds on the door intercom and the mobile unit for
approx. 5 minutes.
!
To switch off the tamper alarm, press the on/off button
the talk button [1] on the mobile unit.
16. Wireless range
The wireless range is dependent on many factors. In an ideal location
and by free line of sight between both antennas) a range of up to 150
m is possible, within buildings this is reduced to maybe 20 m.
The range cannot be guaranteed as it is dependent on the local conditions.
In order to avoid malfunctions, only one wireless system should be fitted for
each monitoring location/building/home.
A reduction of the range will be caused by:
#
Walls and Floors, in particular those of metal or with metal
reinforcement
#
Sheet metal surfaces e.g. refrigerator, metal shelves
#
Coated windows (eg. those with Insulating glass), radiators, and
metal surfaces
#
Strong electric fields and other radio equipment, eg. microwave
ovens, radio telephones, mobile phones, radio equipment in the 2.4
GHz range, electric motors and power cables
#
Devices using the same or similar frequency (eg. WLAN-systems)
