**GTE ADICOS AAB-L Junction Box Instruction Manual

**

Abstract

The Advanced Discovery System (ADICOS®) is used for early detection of fires in industrial environments.
It is comprised of various, separate detector units. By parameterizing and arranging the detectors appropriately, the system fulfills a predefined detection goal.
The ADICOS system ensures reliable early detection of embers and smoldering fires even in adverse environments.

ADICOS AAB-L serve as wiring aids for ADICOS detectors.
They are are large, high-quality surface-mounted junction boxes with internally pre-connected double-pole terminals, which enable the electrical connection of ADICOS detectors of all models to the special fire alarm system in a very simple way.
Thanks to their robust mechanical design, the branch boxes are protected against the ingress of dust and moisture and can be installed and used in harsh industrial environments in the vicinity of the ADICOS detectors.

Features

• High quality distribution box made of stainless steel
• Spacious design
• Simple assembly thanks to offset fastening straps
• Maximum moisture and dust resistance
• Optimum wiring conditions thanks to large connection space, wiring channel inside the housing, high-quality and internally pre-wired double-level terminals
• Connection of supply voltage, M-Bus, external fire alarm LOOP as well as alarm and fault contact
• Power supply terminals for external power supply unit
• Up to eight cable glands (4 x M20 pre-mounted, further 4 x M25 enclosed)
