Performance check
Due to the built-in operating monitoring function, the detector is automatically
subjected to a performance check. However, an additional performance check
should be carried out once a year. To do so, proceed as follows:
Activating the test alarm
1. On the control panel, switch off the remote transmission of alarms. To do this
set the 'Detector test' operating mode on the control panel.
2. Hold the alarm test filter TF04 in front of the hood, such that it covers the
detector optics.
 The detector activates an alarm after around 10 seconds.
3. On the control panel, switch the remote transmission of alarms back on.
4. Check the detector for mechanical damage.
5. Replace detectors that do not respond or are mechanically damaged.
If the alarm doesn't sound:
Check whether the standardized signal value is attenuated enough to reach the

alarm threshold. Otherwise rotate the alarm test filter a little or turn it round.
