The government wants to spend £4.9m replacing the emergency services’ communications system.
Home Affairs Juan Watterson MHK will ask Tynwald to support funding at the October sitting.
The investment is needed to fund the replacement of the Terrestrial Trunked Radio (TETRA) system, which has reached the end of its operational life after 11 years of service.
TETRA provides secure and reliable communications for the police, fire service and ambulance service.
The system is used by a further 18 organisations across the government and is essential to the safe running of many high-profile events, including the island’s motorcycling festivals.
There are 3,300 terminals in operation and TETRA has handled almost 15 million calls since it was installed in 2003. One of its main functions is to co-ordinate the response to emergencies and major incidents, such as this year’s storms and coastal flooding.
