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).
- 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.
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.
