Most Housing/Warden call schemes rely on a telephone line as a single emergency communication link with residents despite the advancements in fire and dispersed alarm technology in recent years. In the case of hard wired scheme equipment 30+ residents and a fire alarm panel could be left vulnerable if the line was in use or failed during an emergency.
Whilst for the foreseeable future we will remain dependent upon telephone lines, the risk can now be significantly reduced by utilising a robust wireless back-up path that can access any available mobile phone network.
