or intelligent detector tester
l
FDUD292, FDUD293
You will find more information about the tools in document 007228. See the
chapter 'Applicable documents [
7]'.
A firmware version
≥
3.1.8 must be installed on the FDUD292 and FDUD293.
The FDUD292 and FDUD293 also display the bus address in the alternative
protocol in the 'AnalogPLUS' and 'SIGMALOOP' modes.
Format: 255/xy, where 'xy' represents the bus address.
4.1.4.2 Testing detectors without detector exchanger and
tester/detector tester
The fire detectors are highly resistant to deceptive phenomena. This means that
optical fire detectors, for example, will recognize the immediate occurrence of
smoke (such as that which occurs during testing with test gas) as a deceptive
phenomenon and will not trigger an alarm. This is desirable in normal operation;
however, it does make testing with test gas problematical.
To enable detector testing with test gas or hot air, the detector must be switched to
test mode. Testing with test gas or hot air is performed differently on addressed
detector lines and collective detector lines.
FDnet, SIGMALOOP, interactive detector lines
The detector is set to test mode when the detector or the detector group is
switched to 'Test' on the control panel. The detector can be tested with test gas or
hot air.
If a FDOOT241-A4 point detector is operated under SIGMALOOP in sensor mode
'0', it cannot be activated with hot air.
