Direct the UV test sensor (ATEX) to the UV flame detector to be tested and
switch it on.
The time until an alarm is signaled depends on
(1) the intensity of the UV radiation (UV test sensor (ATEX))
(2) the distance between the radiation source and the sensor
(3) the response sensitivity of the UV flame detector
(Setting of the evaluation function)
(4) how soiled the visual pane of the UV flame detector is
(if necessary, clean the visual pane prior to the fire alarm test)
Minor UV radiation (intensity) detected.
This message is not mandatory.
Does not trigger a fire alarm, is active for 30 sec. max.
Medium UV radiation (intensity) detected.
This message is not mandatory.
Does not trigger a fire alarm, is active for 30 sec. max.
Sufficient UV radiation (intensity) exists, fire alarm detected.
Relay – K1 (fire alarm)
Fire alarm (pulled)
Intensity of the UV radiation
depends on the settings of the evaluation function.
Check that the fire alarm on the central fire alarm system is detected based on
the operating manual of the central fire alarm system.
Reset the fire alarm.
(1) For a continuous alarm, in order to reset, interrupt
the operating voltage of the UV flame detector for approx. 1 sec.
(2) For automatic resetting, wait for the time to elapse until the
UV flame detector resets.
Depends on the settings of the evaluation function.
Interrupt the resetting the operating voltage of the UV flame detector
for approx. 1 sec.
