ADICOS HOTSPOT-Ex IR Heat Detector 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.
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-Ex detectors are designed for operation within explosive atmospheres up to ATEX zone 20.

Personnel Qualification
Any work on ADICOS HOTSPOT-Ex may only be performed by qualified personnel. Persons, who can perform work on electrical systems and recognize possible dangers based on their professional education, knowledge, and experience as well as knowledge of the applicable provisions, are considered qualified personnel.
WARNING!
Personal injury and property damage! Improperly performed work on and with the device can lead to malfunctions.
Installation, startup, parameterization and maintenance may be performed only by authorized and properly trained personnel.
Handling Electrical Voltage
DANGER!
Risk of explosion by electrical voltage in potentially explosive atmospheres!
The electronics of ADICOS HOTSPOT-Ex detectors requires an electrical voltage that can trigger an explosion in potentially explosive atmospheres.
- Do not open enclosure!
- De-energize the entire detector system and secure against unintentionally reactivation for all wiring work!
Modifications
WARNING!
Property damage or detector failure by any form of unauthorized modification!
Any form of unauthorized modification or extension can lead to a failure of the detector system. The warranty claim expires.
Never make unauthorized modifications on your own authority.
Accessories and Spare Parts
WARNING!
Property damage due to short circuit or failure of the detector system The use of parts other than the manufacturer’s original spare parts and original accessories may result in property damage due to short circuits.
- Only use original spare parts and original accessories!
- Original spare parts and accessories may only be installed by trained specialist personnel.
- Qualified personnel are persons as described in Chap. 2.3.
