Occupancy Sensor Heads

The PIR (passive infra-red) detector senses movement of warm bodies against a cooler background and sends the information back to the Lighting Control Pack. The detection pattern is broadly rectangular at 7.4m x 5.6m when fixed at a ceiling height of 2.5m (longest length of detection aligning with the spring clips).

Occupancy Sensor Head

fnh200 (Master Head)

The standard offering for straightforward occupancy sensing. Inbuilt infra-red receiver accepts commands from either the Setup or User hand held Remote Controls, whilst an LED provides indication of operation.

Requires a 1000, 2000, 3000 or 4000 Control Pack and Link Lead to operate.

Occupancy Sensor Head With Light Level Sensing

fnh400 (Master Head)

All the features of the fnh200 but with the addition of a light cell for accurate lux readings under the head.

Requires a 1000, 2000, 3000 or 4000 Control Pack and Link Leads to operate.

Auxiliary Occupancy Sensor Head

fnh/aux (Auxiliary Head)

Up to 5 Auxiliary Heads can plug-in parallel with an existing Master Sensor Head (either of the above), increasing the detection range up to 6 fold. Each Auxiliary Head comes with a ‘Y’ adaptor to facilitate parallel connecting.

Tamper-Resistant Sensor Head

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.
