20. Maintenance
HYDROSENSE HSCP control panels do not require any specific maintenance but should the control panel
become dirty it can be wiped over with a damp cloth and should then be dried with a dry, lint free cloth.
Detergents or solvents should not be used to clean the panel and care must be taken that water does not
enter the enclosure.
The control panel contains sealed lead acid batteries to provide standby power in the event of a mains
failure.
These batteries have a life expectancy of around 4 years. It is recommended that these batteries be tested
in accordance with the battery manufacturer’s recommendations annually to determine their suitability for
continued standby applications.
Routine testing of the Hydrosense Water Detection System will identify any malfunction of the control panel
and any malfunction should be reported to the alarm maintenance company immediately.
Should the control panel become faulty the complete electronic assembly can be replaced.
To do this, any configured options should be noted then both mains and battery power should be removed
before the work is started.
The field wiring should be carefully labelled and removed from the terminals.
The PCB can now be taken out of the panel by removing the 2 holding the plate in position.
Fitting the new PCB is the reverse of the procedure for removing the board.
21. Zone designation label
All HYDROSENSE HSCP control panels are supplied with a zone designation label onto which zone designations
can be written.
