7.1 Status polling with the detector exchanger and
tester
All point detectors are equipped with the MC link (Maintenance and Commissioning
Link).
Using this interface, it is possible to read out data from the device in a proximity
method over short distances with the detector exchanger and tester FDUD292 or
the intelligent detector tester FDUD293.
You will find more information in documents 007227 and 009718.
Depending on the authorization level of the user and the control panel type, the
following actions can be performed:
● Device test
– Deviation/No deviation
– Detailed status request
1
● Activation of a test alarm
● Reading out the identification number, customer text and measure text
1
● Localization and parameter setting of the detector (parameter setting not in
FDnet mode)

Actions cannot be carried out using the intelligent detector tester FDUD293.

7.2 Performance check
The selftest automatically subjects the detectors to an extensive electrical
performance check. Regular performance checks of the detectors are required
nonetheless.
The performance check can be undertaken using the following tools:
● Detector exchanger and tester FDUD292
● Intelligent detector tester FDUD293
● Test gas
● Hot air
Recommendation:
● Check the devices every year.
● Replace heavily soiled or damaged devices.
● All point detectors should be replaced after 6 to 8 years of service, depending
on the ambient conditions.
