The mains supply cable must remain connected to the Power supply assembly, but the mains power must remain switched OFF.
Sequentially connect each external circuit one at a time and test it to ensure it is working correctly. It is a good idea to first pull out those terminal blocks of the external circuits to be tested later. Start
with the loop circuit and leave only Loop End-1 connected in preparation for the power up.
The master alarm circuits will require an end-of-line resistor to be fitted at the last alarm device to prevent fault events being raised at the panel. If the master alarm circuits are not being used then
ensure the resistors are fitted to the Master Alarm circuit terminal blocks on the MCB.
