fnh200/s (Master Head), fnh400/s (Master Head) & fnh/slave/s (Slave Head)
The sensor heads above are also available in a ‘tamper-resistant’ design, intended specifically for installations where resilience to unsolicited attempts to remove or tamper is paramount – prisons, secure units etc. The head can be mounted directly to the ceiling (32mm⌀ hole required) or a standard conduit box, and is then secured with two suitable security screws (not supplied).
fnh200/s & fnh400/s requires a 1000, 2000, 3000 or 4000 Control Pack and Link Lead to operate.
