Eircom has sold its monitored alarm operation to a Norwegian company.

In a statement, the telecoms provider said it sold PhoneWatch to Sector Alarm Corporation of Norway as it was not a core business unit.

Eircom says service to all PhoneWatch customers will continue as usual, without impact and all customer contracts remain in place.

"The proceeds will be used to support our strategic plan to deliver long term stability for the Group as the key telecommunications provider in Ireland," Herb Hribar, CEO of Eircom commented on the transaction.
