Mains Wireless Interconnected Smoke Alarms.

Zoomup:

These work on a frequency of 868.499MHz. Is it possible that they can be interfered with or blocked by anything?

Most definitely, the 868mhz bandwidth is commonly used by a plethora of electronic products, some professional end security systems utilise channel hopping technology to mitigate the risk of interference not so sure that this carries over to fire alarm devices though, maybe a call to the manufacturer may be the best course of action.
