1. Safety Instructions

The AR-024 occupancy sensor is an explosion-safe product suitable for use in hazardous areas with explosion hazard

from flammable gases, vapors, mist and dust, classified as Zone 2 or Zone 22.

This manual must be read and understood for safe use of the occupancy sensor. All warnings and instructions must be

followed.

Installation must be carried out by personnel trained and qualified in explosion safety taking the instructions

mentioned on the equipment and in this manual into consideration. Local regulations that apply to the installation

must be followed.

Connect this equipment to the supply voltage for which it is designed.

Isolate electrical power to the occupancy sensor before electrical installation.

The protection degree against ignition “Encapsulation”, “Increased safety” and “Protection by enclosure” have

been applied to the apparatus. The enclosure may not be opened if the occupancy sensor is energized.

Installation of cables may not invalidate the “Protection by enclosure”, therefore only IP65 cable glands with the a

clamping size meeting the cable diameter should be used.

All unused openings should be plugged off in a properly closed and tight way.

Either decommission the occupancy sensor or do not use it when it is damaged.

During installation of the occupancy sensor national safety regulations must be observed.

Only use the occupancy sensor under the environmental conditions for which it is specified. Deviating

environmental conditions can contribute to damage to the equipment and may lead to possible danger to the life

of the user.

Do not use the occupancy sensor at temperatures deviating from the specified ambient temperature range.

Follow all instructions written on the equipment and as mentioned in this manual.

Repairs may only be carried out by the manufacturer or by a person appointed by the manufacturer.

Modifications to the equipment or changes to the design are not permitted.

The product may only be used for the function for which it is designed and shall be maintained in a good and

clean condition.

If these instructions are not followed, the explosion safety of the equipment cannot be guaranteed. The equipment

could then endanger the life of the user and could cause the ignition of an explosive atmosphere. Consequently, Artidor

as the manufacturer will waive any responsibility.

2. Description

The explosion-safe occupancy sensor AR-024 is based on passive infrared technology and capable of detecting

movements of heat sources. Thanks to the wide opening angle and its 10 m range, this sensor is suitable for

User manual explosion-safe AR-024 occupancy sensor

monitoring large areas. The occupancy sensor is designed for use inside large buildings for example warehouses and

combines energy saving and the protection of the environment in addition to convenient lighting.

Motion sensors switch the light depending on movements and the ambient light. Lighting will be switched off. The

sensor itself does not emit any radiation and is therefore called “passive”. Unlike motion sensors, occupancy sensors

can also switch off lighting if there is sufficient daylight, because of their advanced mixed light measurement (the

principle on which occupancy sensors are based). Do not install sensors near heat sources like air-conditioning units,

lights or radiators. The sensor electronics offers an potential free contact for switching up to 1,150 VA load.

The occupancy sensor is mounted on top of a coated aluminum housing. The explosion safety to gas and dust is

arranged by the appliance of protection degrees against ignition “encapsulation”, “molding”and “protected by

enclosure”.

The Artidor AR-024 occupancy sensor is certified in accordance with European Directive 2014/34/EU (ATEX 114) for

use in gas or dust hazardous areas and is CE marked.

Flashing regularly

Sensor identifies bright, light off (dependent upon operating mode)

Not illuminated

Sensor identifies dark, light on (dependent upon operating mode)

Flashing extremely rapidly

Too bright / Too dark / Undefined

Red LED as an acknowledgement of receipt for commands from the remote control

Illuminated for 1 seconds

Signal validly received

Illuminated for 0.25 seconds

Not-accepted command, sensor blocked

Flashing extremely rapidly

Not-accepted command, occurs, for example, when an attempt is made to set a twilight-value that is too high or

too low

Red LED as an acknowledgement of receipt for commands from the remote control

Red and green LEDs flash 3x briefly every 5 seconds

Indicates semi-automatic mode

Red and green LEDs light up alternately

time of 30 minutes.)

11. Maintenance

For the maintenance of the AR-024 occupancy sensor the requirements as stated in EN 60079-17 apply. If the

occupancy sensor or the connection cable is no longer in good condition, very dirty or damaged, it must be repaired or

cleaned immediately. The power supply to the occupancy sensor must be switched off and may only be restored after

the maintenance has been carried out and approved.

The advised maintenance cycle for this occupancy sensor depends on its specific use and must therefore be agreed

upon with the user for the expected use.

12. Repair

If repairs are carried out in an incompetent manner, the explosion-safety of the occupancy sensor can no longer be

guaranteed. Therefore it is preferred that the occupancy sensor is returned to the manufacturer for repair.

13. Removal / re-use

The equipment can be completely processed as electronic waste. For processing regarding disposal or reuse of the

product and its packaging, national disposal and environmental laws and legislation must be taken into consideration.
