The dual technology KX15DT combines both PIR and microwave detection to allow for more accurate and reliable detection while minimising the risk of false alarms. With adjustable settings like sensitivity and pulse count, the KX15DT is ideally suited for different environments and security requirements.

Key Features
  • 15m, 85° volumetric coverage
  • Selectable EOL resistors
  • Auto sensitivity feature

Product Features

The KX15DT features Dual element pyro-electric sensor with X-band DRO based microwave both of which need to be triggered to set off the Alarm, this reduces the risk of false alarms.

With Blue Wave Technology (BWT) and digital temperature compensation the detector will adjust its sensitivity, further enhancing the detectors immunity to false alarms and environmental disturbance.

15m Volumetric detector

15m Volumetric detection coverage. Ideal for protection of rooms and offices in commercial environments.

Selectable EOL resistors

The detector incorporates selectable alarm resistor values of 6K8, 5K6, 4K7 &1K & tamper values of 5K6, 4K7, 2K2 and 1K catering for most control panels on the market.

AND/OR technology

‘AND’ mode operates as a standard dual technology detector, where both technologies need to active to cause the alarm. ‘OR’ mode will switch the sensors activation of the alarm input to be either the PIR ‘OR’ Microwave. This can be useful in  environments where there is a risk of PIR detection being blocked.

Auto Sensitivity Feature

Depending on the environment condition, the detector will automatically adjust the sensitivity.

Triple LED indication

Microwave – orange, PIR – green, alarm – blue

Microwave Frequencies Bands

3 different frequency bands to avoid interference between detectors are installed in the same room.

Active self test

If there is no activation after a 5 hour period it will actually self test both the PIR and microwave.

Blue Wave Technology (BWT)

This technology further enhances the detector’s immunity to infra-red noise in the environment. BWT comprises of some key components:

The new 3D optics system enables perfect focusing of the infra-red signal onto the pyro-electric sensor. This allows BWT to clearly identify the positive and negative signal edges.
Digital temperature compensation digitally adjusts the detectors sensitivity to ensure performance is maintained
Powerful software embedded into a microprocessor is used to process the received information from the pyro-electric sensor. The result of this combination is lower infra-red signal noise amplification and therefore better immunity.
