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 heads
  • Discreet Sensor Head.
  • Increase detection 6 fold range by adding extra sensor heads.
  • Adjustable timeout period.
  • Max no. of ballasts: 25 (all versions).
  • Supply Voltage: 12V

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

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.

fnh/slave (Slave Head)

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

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.

Occupancy Sensor - Tamper Proof

Adaptor Plate

Enables either of fnh200, fnh400 or fnh/slave sensor heads to be surface mounted.
