These systems allows the visitor to call the resident via the BT line. The resident is then able to unlock the gate or door using a button on their telephone.
The systems are available to suit any size of system from a single button system to a multi button system for gated communities.
The systems can link either to a standard PSTN phone line or an analogue extension off o standard switch.
The systems come in varying sizes and finishes.
Suitable applications include…..
- Remote locations where it is difficult to run a cable
- Long drive ways
- Boundary gate locations
- Blocks of flats or offices where cabling to each resident would be expensive or difficult
- Where heritage or planning restrictions preclude running cables.
The New GSM versions now allow the system to be almost completely wire free . The newest addition to the range allows a simple SIM card to be inserted and all calls to the residents to be via a SIM card.
