The placement of vhfBridge determines its distance from the hub and the
presence of obstacles between them that impede the passage of the radio
signal: walls, inter- oor constructions, or large-sized objects located in the
room.
Be sure to check the signal strength at the installation site. If the signal strength is low (a
single bar), we cannot guarantee a stable operation of the security system. At the very
least, relocate the device as repositioning even by 20 cm can signi cantly improve the
signal reception.
If after moving the device still has a low or unstable signal strength, use a
When choosing the installation location, consider the distance between
vhfBridge and the VHF transmitter — the cable length should be su cient for
connection.
The minimum distance between vhfBridge and the radio transmitter is 2 meters and the
maximum distance is 7 meters. The minimum distance is required to avoid signal
overlapping. The maximum distance allowed will help avoid signal attenuation in the
cable.
The material and cross-section of the cable for connecting the VHF transmitter
are determined by the requirements of the manufacturer of the VHF transmitter
and the maximum current value. All requirements can be found in the manual or
from the customer service of the VHF transmitter manufacturer.
vhfBridge installation
Prior to mounting vhfBridge, ensure that you have selected the optimal place to install
the device corresponding to these instructions.
The transponder body should be mounted on a vertical surface. If installed on a
horizontal surface, the
