7.3 Testing detectors
Depending on the detector, testing may be performed with one or more of the
following accessories:
z Detector exchanger and tester FDUD29x (recommended)
z Test gas
‒ REF 8-S (recommended)
‒ REF 8
z Hot air fan
The following table shows which detectors may be tested with which test aids.

Depending on the detector, the following must be taken into account:

To be considered
FDOOT z The FDOOT with ES < 13 reveals the same optical and thermal
sensitivity level in all parameter sets.
z From ES 13, the detector reacts in correspondence with the
parameter set in test mode. This means when the neural fire detector
is operated as a heat detector (sensor mode 1), it must be thermally
checked as well.
FDO z The detector reacts optically with medium sensitivity (2 %/m).
FDT z The detector reacts when a temperature of 60 °C is reached or at a
temperature increase of 22 K/min.
When the detector is in alarm condition, the internal alarm indicator flashes
brightly every second.
