All FM wire-free alarms
operate over VHF frequencies. VHF technology has high building material
penetration properties and an extended communication range capability
– making it ideal for demanding developments.
Alarm systems managed by
the FM4000Xtra control panel offer a very high level of property
protection. Frequently FM systems are deployed in situations where
a high- performance wire-free system is essential to protect ‘difficult
properties’.
