Maintenance
Chapter 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
Read Chapter 2 Safety before carrying out any work on the system.
Warning
If the relays are switching mains voltages, hazardous live terminals may be present within the
Relay Output Module even if the Touchpoint Plus system is isolated.
Ensure that all current is isolated and dissipated before touching live terminals.
8.1 Routine Maintenance
Caution
Test outputs will be generated and relays will be activated during Cause and Effect Testing.
Ensure that relay activated output systems (i.e. emergency deluge / sirens etc.) are isolated before starting the
test.
Caution
While an Operator could Force a channel, an Engineer is required to isolate services, carry out tests, Clear
Force, and restore the system to full operational status.
For these reasons Operators are advised to carry out visual inspections and cleaning only, unless under the
direct supervision of the engineer.
