The KX18DC has a long narrow coverage pattern that makes it ideal for protecting shop fronts and large windows.

With Bluewave technology, auto sensitivity and digital temperature compensation the KX18DC will keep you protected, automatically adjusting the detector to match the environmental conditions such as infra-red noise, light and temperature.

18m Vertical curtain detector

18m Vertical curtain detection coverage. Ideal for protection of large windows areas.

Selectable EOL resistors

The detectors 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.

Blue wave technology

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 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.

Auto sensitivity feature

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

Digital Temperature Compensation

When the product is used in a hot environment this technology digitally adjusts the detector’s sensitivity allowing it to maintain its range even when the background room temperature is almost equal to the external body temperature of 32ºC (internal body temperature = 37ºC).

Tamper proof brackets

Supplied with both wall & ceiling mount brackets which provides access for up to two 8 core cables (Tamper kit optional).

Sealed optics

Protects from possible infestation from insects, shields air movement in front of the pyro-electric sensor and protects against adverse reflections from inside the detector housing.

ABS plastics

3mm polished finish, reduces electrostatic interference on the PIR sensor.
