The water & floating pontoon areas are covered by all UK mobile phone networks. However, like most rural locations, reception may vary in specific areas. It is advised you check your mobile network if using this as a line of communication for your dive project/plan.
The site is a rural location and the water area is 34m below the car park. The lake is surrounded by limestone walls over 200ft in height.
NDAC staff carry hand-held radios and link to the main building and main line phone at all times.
The Emergency Panic push button alarm system on the floating pontoons is linked into the main site's intruder alarm system if activated.
To activate the alarm push the button with your hand. A radio link will activate the alarm at the centre so centre staff know there is an incident. There is also a hand held radio in the blue shed if required to speak to NDAC staff.
CCTV is in operation throughout the site 24 hours a day and monitored for the purposes of crime prevention and public safety. This scheme is controlled by the National Diving & Activity Centre. For further information please contact us.
