The best in Brazil

For 7 consecutive years, JFL Alarmes alarm panels are considered the best in the country, chosen by the electronic security professionals.

* Trio International Distinction in alliance with Security Brasil magazine.

Bus Technology

Technology that enables communication between the alarm panel and up to 32 detectors with just one pair of cables. Saving and organization of wiring, low consumption detectors and periodic supervision are some of the advantages when using the BUS line.

Digital PIR

With high technology detection, this detector was developed to quickly and accurately analyse any movement, which makes the alarm system even more safe and efficient.

Animal Immunity

PETs don’t need to be left outside so that the security system can be armed. With the animal immunity feature, the intelligent detector does not detect small animals, that is, there is no detection, no alarm activations.

*Check detector minimum weights (20 kg or 30 kg) detection.

Sensitivity adjustment

In order to make the electronic security professional day to day easier, this detector has a sensitivity detection adjustment, that is, it’s possible to detect in 3 different detection levels: minimum, medium or maximum. Precise adjustments that provide safety and avoid false alarms.

Temperature compensation

The detector’s main internal components have the capability to automatically compensate the temperature, which allows high performance when detecting movement.
