HAA54 – PIR MOTION DETECTOR

1. Description

The HAA54 employs “Double-Twin Optics”-technology and the security logic is supplied by the

ASIC-processor (Application Specific Integrated Circuit), which was developed for this specific

application.

The Double-Twin Optics system combines two optical structures and heat detectors in one

housing. Both heat detectors are equipped with a dual element that produces low-level noise

only. This enables the HAA54 to create a detection pattern that only reacts to actual intruders

and ignores pets or rodents.

The Double-Twin Optics system is controlled by the ASIC-processor. This processor detects the

change in polarity of a signal caused by an intruder. Thanks to this technique, both channels

have a high degree of immunity against common radio interference and power surges. This

processor also provides the HAA54 with a number of additional functions : digital pulse counting,

temperature compensation, warm-up delay, alarm controls and an alarm activation delay. These

characteristics maximise security and provide excellent protection against false alarm.

2. Features

• “Double-Twin Optics” detection system

• Detection with changing polarity of the signal

• Security logics are integrated in the ASIC-processor

• SMD technology, greater EMI (electromagnetic immunity) and better protection against RFI

(radio frequency interference)

• Automatic temperature compensation

• Normal response or pulse counting for “HARSH” (unstable) environments
