Calibration of supervised outputs (H5/A1)
Supervised (monitored) outputs
The voltage outputs (S0-S3) in each control unit.
The voltage outputs (VO0-VO1) in the COM loop output unit 3364.
When all alarm devices (sounders, etc.) have been connected,
including required end-of-line devices
57
and when the SSD is
downloaded, a calibration has to be done.
Function: The calibrated range is 4K7 – 50K and 470 – 5x470 nF
respectively. If the actual value at any time differs from the calibrated
value ± a small tolerance or if the calibrated value is outside the
calibration range, a fault will be generated.
NOTE!
Each output's logic is programmable via WinG3, i.e. normally low
(default) or normally high (24V). During the calibration the outputs
have to be low, i.e. a normally high output will be low a few seconds
during the calibration.

NOTE!
After the calibration it is recommended do a "Safe shutdown
of the control unit" (see menu H8/S6). This will save the SSW data
(e.g. the calibration values) in a Flash ROM (see page 137).

Control unit outputs S0-S3: One end-of-line resistor (33K) in the last unit
or one resistor (33K) in up to five units.
3364 outputs (VO0-VO1): One end-of-line capacitor (470 nF) in the last unit
or one capacitor (470 nF) in up to five units.
