Active Infrared Barrier
ACTIVA
activa_en 03/15
The ACTIVA is a series of photoelectric devices which serve as active infrared barriers. Each device
is composed of a transmitter and a receiver units. The ACTIVA barrier is available in seven models
which differ among themselves by the number of beams/height:
•
ACTIVA-2 (2 beams, height: 52 cm),
•
ACTIVA-3 (3 beams, height: 78 cm),
•
ACTIVA-4 (4 beams, height: 105 cm),
•
ACTIVA-5 (5 beams, height: 130 cm),
•
ACTIVA-6 (6 beams, height: 158 cm),
•
ACTIVA-7 (7 beams, height: 184 cm),
•
ACTIVA-8 (8 beams, height: 210 cm).
This manual applies to the ACTIVA barriers with firmware version 2.00 (or later).
1. Features
•
Coding of infrared beams, which prevents swapping of the transmitters (light entering the receiver
from another infrared source will be interpreted as beam interruption).
•
Beams sensitivity adjustment.
•
Option to automatically bypass the beams after preset number of interruptions.
•
Option to permanently disable the beams.
•
Selectable number of beams whose interruption will trigger an alarm.
•
Memory of bypasses.
•
Signal strength adjustment (barrier range).
•
Programming capability by using the ACTIVA program.
•
Tamper switch for detection of an attempt to open the cover or tear the device off the wall.
•
Esthetic and durable covers made of aluminum and polyamide.
•
Designed to prevent water ingress and allow easy drainage.
2. Description of electronics boards
Electronics boards of the ACTIVA barriers have a modular structure. Depending on the model of the
device, they differ by the number of interconnected basic components. Presented below is a
description of simplified views of the transmitter and receiver electronics boards.
