ADICOS Sensor Unit & Interface
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. The detectors of the HOTSPOT® product series are equipped with thermal imaging sensors and use infrared measurement technology and intelligent signal analysis to detect all types of smoldering fires and open fires, even in the incipient stage. The fast response speed of 100 milliseconds enables the monitoring of conveyor belts or other conveyor systems, e.g. on moving embers. ADICOS HOTSPOT-X0 consists of the sensor unit and the ADICOS HOTSPOT-X0 Interface-X1. The ADICOS HOTSPOT-X0 Sensor Unit is an infrared sensor unit that, in combination with the ADICOS HOTSPOT-X0 Interface enables an optical and spatially resolved fire and heat detection in potentially explosive atmospheres of ATEX zones 0, 1, and 2. The ADICOS HOTSPOT-X0 Interface-X1 is an interface between the ADICOS HOTSPOT-X0 Sensor Unit and the fire control panel within potentially explosive atmospheres of ATEX zones 1, and 2. Additionally, it can be used as a connection and branching box (AAB) within these zones.

- Installation work may only be performed by specialist personnel! (–› Chap.
Personnel qualification)
Explosion Protection! Risk of explosion
In contrast to the ADICOS HOTSPOT-X0 Sensor Unit, the ADICOS HOTSPOT-X0
Interface X1 is not approved for installation within ATEX zone 0.
- Interface-X1 may only be installed outside of ATEX zone 0.
Mounting
WARNING!
Danger of malfunction and failure of the detector system Incorrect installation of ADICOS detectors can lead to faults and failures of the detector system.
- Installation work may only be performed by specialist personnel! (-> Chap. 2.3, Personnel Qualification)
Selecting the Mounting Location
Mounting Location of HOTSPOT-X0 Sensor Unit
WARNING! Correct alignment Arrangement and alignment of ADICOS detectors are highly important for reliable detection. Unfavorable placement can lead to complete ineffectiveness of the detector!
- Only experienced specialist planners may define detector position and alignment!
NOTICE!
Danger of sensitivity loss and failure of the detector system In dust environments with simultaneous high humidity, the functionality of the detector may be impaired.
- Ensure that purge air is applied! This allows you to extend the cleaning-related maintenance intervals!
- In case of high dust exposure in combination with high air humidity, contact the manufacturer for consultation!
Mounting Location of HOTSPOT-X0 Interface-X1
WARNING! Explosion danger!
Unlike the ADICOS HOTSPOT-X0 sensor unit, the ADICOS HOTSPOT-X0 interface- X1 is not approved for installation within ATEX zone 0, but only for zones 1 and 2.
