8. Maintenance
This chapter describes how to perform common maintenance operations and upgrades.
The required frequency of inspection and maintenance will depend on local site conditions and will need to
be established through experience. Please refer to IEC/EN 60079-29-2 or other local or national regulations
for guidance on establishing an appropriate maintenance routine.
WARNING
If the relays are switching mains voltages, hazardous live terminals may be present within the
Relay Output Module even if the Touchpoint Pro system is isolated.
8.1 Testing the Touchpoint Pro System

8.1.1 Introduction
The Touchpoint Pro system has four test modes available, which together enable a full test of the system.
The test modes are:
1. LED Panel Test -- tests that all of the panel LEDs are working.
2. Field Inputs Test – test all input channel devices without affecting any outputs. Gas test, force mA,
conrmationofcorrectdeviceconnectionetc.
3. CongurationSettingsTest–forcetheTouchpointProinputchannelstospeciclevelsandviewthe
corresponding states, threshold alarm levels, over-range, warning/fault etc.
4. Cause and Effect Test (carried out from the output channel menu) – force the Touchpoint Pro input
channelstospecicstatestotestthatthecorrectoutputchannelsareactivated.
WARNING
In all four test modes, the Touchpoint Pro system is not operational as a safety system and
any eld device inputs will be ignored.
Caution: During the Cause and Effect Test, outputs will be generated and relays will be activated.
To avoid any unwanted activation of output devices (e.g. emergency deluge) disconnect them before
starting the test.
When any of the test modes is active, the System Failure relay will activate to indicate that the safety
function of the system is not operating. In addition, a “Test Mode” Fault will be shown as an Active Event on
the User Interface, which cannot be reset.
Once a test mode is active, the system will remain in test mode until the test is exited. The only exception is
in the case of a power cycle of the Touchpoint Pro system, when it will restart in normal mode. Cause and
Effect Test inputs can be forced and cleared from any output in that Test.
Note: After 20 minutes of inactivity the system will always logout the user and return to the System Status
screen, however it is still running in test mode.
