Arming the system after quarterly maintenance
After successfully completing the maintenance check, do the following:
• Submit a report of the findings to the system owner or his delegated
representative.
• Restore the system to normal and reset.
• Lock the system off while restoring the actuator.
• Remove the transit pin from the extinguisher cylinder (if applicable).
Fault finding
Faults that occur on the ECU or in building wiring are reported by the fire alarm
control panel. The Fault LED on the ECU front panel illuminates. When a fault
occurs, it should be dealt with as quickly as possible. In some cases the operator
will be able to rectify the fault, but usually a call will be made to the servicing
company.
A comprehensive guide to faults that can be raised by the panel is provided in
Chapter 3 “Fault finding – ECU faults” on page 15. Information is also given as to
the appropriate actions to take in each case.
