DualCom is suitable for the majority of premises in the UK. A major advantage of DualCom is its ability to operate over any telephone network. This means your customers do not have to install a dedicated telephone line for alarm signalling. If sharing the telephone line, three-way calling should be enabled which ensures that DualCom signals take priority over any calls, faxes, modems etc. should an alarm need to be transmitted.
Prior to installing DualCom we recommend a few basic, but important, procedures. It is necessary to check that there is sufficient signal strength in the premises of installation. This can be done via the following options:
This test kit searches for the strongest signal in the premises. Once located, you can carry out additional tests such as RSSI and FSSI (reverse and forward signal strength i.e. to and from the nearest base station). Bit error rate can also be checked. This will highlight possible sources of interference e.g. fluorescent lights.
With the postcode of the relevant premises, you can check the likely signal strength by clicking on the link below, entering the network type (Paknet or Vodafone GSM), and typing in the postcode to get an approximate signal strength reading of the level of signal available for that area. However, please note that this method does not take into account local interference such as a metal skinned building etc.
