Maintenance

Maintenance
Before opening the detector housing, make sure that the alarm panel is in
installer mode. This prevents the tamper alarm from being triggered.
Danger
Test during routine maintenance that the detector works properly. Check the tamper contact.
Check for signs of insects having made their way in to the device and clean as required.
Replace the batteries every two to three years or if the alarm panel displays the message
"Flat battery in detector". You can find the battery type to be used as a replacement under
Technical data.
After removing the old batteries, wait 30 seconds before inserting the new batteries.
Note
Note:
How to replace the batteries:
• Put the alarm panel in installer mode.
• Remove the screw from the underside and open the housing.
• Take out the batteries.
• Wait 30 seconds, then insert the new batteries.
• Close the housing and re-tighten the screw on the underside.
• Test the system.
