Note!
AGQ1… is only available for AC 230 V mains voltage.
Power supply in operation DC 280…325 V
Power supply in test mode DC 390…750 V
For more detailed information about QRA2… / QRA10…, refer to Data Sheet N7712.
For more detailed information about QRA4.U, refer to Data Sheet N7711.
Caution!
QRA2… (QRA4.U / QRA10... must not be used when extraneous light suppres-
sion is activated since detector tests will not be made in that case!
Possible ionization current Max. 10 µA
Ionization current required Min. 6 µA
In connection with the LMV5…, ancillary unit AGQ1…A27 must be used.

When laid together with other cables (e.g. in a cable duct), the length of the 2-core ca-
ble between QRA… and AGQ… must not exceed 20 m. A maximum cable length of
100 m is permitted if the 2-core cable is run at a distance of at least 5 cm from other
live cables. The length of the 4-core cable between AGQ… and LMV5… is limited to
20 m. A maximum cable length of 100 m is permitted if the signal line (ionization /
black) is not run in the same cable but separately at a distance of at least 5 cm from
other live cables.
