Introduction
The GX30 Globe is a low voltage Passive Infra Red Detector (PIR) designed to meet the
newest and most demanding requirements of the CCTV market. This detector has two
volt free contacts for interfacing to a CCTV or alarm system or both at the same time.
Additionally one of the relays can be increased in time duration and linked to the inbuilt
light sensor which means it can be used to operate a power relay and control lighting.
Detection range is 30 metres out x 70° across. Internal curtains can occlude the
detection area to 10° and lower creep zones may be masked so that the detection
pattern may be tailored precisely to the area to be covered and overspill avoided.
Inside the PIR is a powerful microprocessor which uses logic to determine the validity of
an activation. By combining this technology with the specially designed pet immune
Fresnel lens, nuisance alarms are all but eradicated.
The PIR also contains front and rear anti
-
tamper to detect removal from the wall and
unauthorised adjustment.
Multi beam alignment masking
The multifunction lens produces 7 long range beams and 7 medium to short range curtain
beams. Movement across the beams produces the best response and range, whilst
movement towards the detector will be less responsive. The unit detects the change in
heat and movement in the beam pattern , therefore items such as trees, shrubs, ponds,
boiler flues and animals should be considered when positioning the detector.
The detector is fitted with two sliding shutters to reduce the detection angle.
An additional set of shutters is provided should the beam pattern need to be reduced
further, e.g. if the minimum detection angle of 10
°
is required.
