Installation
Bases are connected together by twin wire. Shielded cable is only required for spe-
cial applications, e.g. in the case of powerful high frequency fields.
Up to 32 HI320C/HI322C may be connected per line depending on specifications of
the line card in the control panel.

Commissioning
In order to avoid soiling the detectors unnecessarily, only insert them in the bases
immediately prior to commissioning.
Activate detectors with detector tester RE6T.
If the response indicator at the detector lights up, the detector is operating correctly.
The line test set DZ1195 can be used for the final testing of installed detection lines.

Maintenance
7.1
Functional check / overhaul
A functional check of the detectors must be performed periodically by forcing each
detector to respond by means of a suitable testing device (e.g. RE6T). Recommen-
dation: Once a year, unless otherwise specified by local regulations. Detectors that
do not respond or which are mechanically damaged must be replaced.
All detectors should be replaced and factory overhauled in intervals of 6 to 12 years,
depending on the environmental conditions and the severity of contamination. Con-
sider possible national regulations.
If mechanically damaged detectors must be scrapped, the plastic materials can be
sorted out based on the embossed code.
