The front cover is opened with a tool pressing both pressure closures located at
EN
both edges of the cover (see Fig.5). For safety reasons, cables must be retained
using the support provided (see Fig.6).
In the case of an installation where cabling is outdoors, it must be installed inside a
cable ducting system with IP4X protection degree classifi ed as "cable ducting with
access cover that can only be opened with a tool" according to UNE-EN 50.085-1:
Cable trunking systems and cabling ducting systems for electrical installations-
Part 1: General requirements.
START UP
Pairing
See REC.AIRSENS RF receiver instruction booklet for steps to follow when pairing.
The 2 minutes pairing window is marked by powering on the receiver mentioned
above. The AIRSENS RF transmitter can always be turned on to be paired. Once the
pairing window has fi nished, when pressing the S2 button on the AIRSENS RF (see
Fig.1), it responds with 5 fl ashes on LED D17 if the sensor is within RF coverage
and paired with receiver. No answer after pressing indicates it is out of coverage
or unpaired.
Pressing the S2 button for 10 seconds erases the pairing code of the AIRSENS
RF emitter. LED D17 will fl ash 20 times in acknowledgement of the command.
IMPORTANT REMARK: Do not do this action unless RF sensor is permanently
removed from installation.
