Entry in the calibration
report
Possible content* Description
10th to max. 252nd
Voltage drop on the
individual 'Voice alarm
sounder beacon/Voice al.
sound. beacon base'
devices on the line
FDS227 - RR
Device 1/2/1/1 PASS U = 23.4 V
Entries 10 to max. 252 show the
calculated voltage drop on each 'Voice
alarm sounder beacon/Voice al. sound.
beacon base' device in the line.
The following results are possible:
● Pass: The calculated operating
voltage for the 'Voice alarm sounder
beacon/Voice al. sound. beacon
base' device in question is ≥ 16 V
for devices with beacon and ≥ 12 V
for devices without beacon.
FDS227 - RR
Device 1/2/1/1 FAIL U = 15.7 V
● Fail: The calculated operating
voltage for the 'Voice alarm sounder
beacon/Voice al. sound. beacon
base' device in question is < 16 V
for devices with beacon and < 12 V
for devices without beacon.
* The specified lines, devices, and values are only examples.
