Maintenance
Caution
Before opening the sounder’s cover, make sure that the alarm panel is in installer mode. This
should prevent the sounder being activated.
You should, however, be prepared for the fact that the sounder might nevertheless be
activated. Make sure that any loud sounds emitted do not startle you, causing you to fall off
the ladder.
Test, during routine maintenance, that the sounder works properly.
Check the tamper contacts.
Check for signs of seeping water or insects and clean the device as required.
Replace
the batteries every two years or if the alarm panel displays the message ‘Flat battery in
outdoor sounder’. You can find the battery type to be used as a replacement under
Technical data
.
Note:
Batteries and the device itself must be disposed of in accordance with the WEEE Directive and
applicable local and national regulations.
Note:
After removing the old batteries, wait 30 seconds before inserting the new batteries.
