118 H-S81-HS Installation & Operation Manual — P/N LS10114-000HI-E:A 2/24/2015
Section 5: Maintenance
System and equipment maintenance must be carried out by skilled staff at regular intervals.
5.1 Steelwork
The steelwork of the H-S81-HS control panel does not require special maintenance. However, we
recommend cleaning and/or replacing the air intake filters located on the cabinet side walls at regu-
lar intervals and, moreover, periodically checking that the terminals connecting the cables from
field devices are properly tightened.
5.2 Batteries
The cabinet contains two dry batteries to power the system in case of primary power supply fault.
The lifetime of these batteries is of approximately 4 years. We recommend checking them every six
months according to the manufacturer's instructions in order to assess their operating capacity.
5.3 Field Devices
For the maintenance of field devices (gas, flame or smoke detectors, etc.) please refer to the rele-
vant product manuals.
5.4 Functional Tests
Carry out the following operations in the following order:
1. Make sure that the green LED “Voltage detection” on the Display module is steady on and all
other LEDs are off.
2. Run the “Control Panel Test” procedure in the operator cycle and check that the control panel
carries out all the operations shown on the display correctly (LED switching on, buzzer
activation, etc.)
3. Cut the mains power from the control panel and check the following conditions:
• The “Primary Voltage Fault” message is shown on the display.
• The yellow LED “General fault” flashes.
• The yellow LED “PSU1 fault” flashes.
• The buzzer operates intermittently.
•The relay “General fault” (K3) is activated.
•The relay “Power supply fault” (K14) is activated.
4. Use a voltmeter to measure the voltage at battery ends and check that it does not go below
24VDC. Otherwise, replace the batteries.
5. Connect the mains power to the control panel and check the following conditions:
• The “Primary Voltage Fault” message on the display resets.
• The yellow LED “General fault” resets.
• The yellow LED “PSU1 fault” resets.
• The buzzer switches off.
•The relay “General fault” (K3) is deactivated.
• The relay “Power supply fault” (K14) is deactivated.
