112.4.1 Alarm Connection ProcedureBefore making any connections to the TPSD2, ensure that the AC power is off at the main breaker box and thecharger’s breakers are off. Verify that no voltage is present by using a voltmeter at all input and output terminals.For relays mentioned as ENERGIZED on alarm condition:If it is desired that the annunciator be active until the alarm triggers, connect the annunciator leads to theNC and C contacts of the desired alarm (located on the relay alarm contacts on S2A-198 board). If it isdesired that the annunciator be deactivated until the alarm triggers, connect the annunciator leads to the NOand C contacts of the desired alarm.For relays mentioned as DE-ENERGIZED on alarm condition:If it is desired that the annunciator be active until the alarm triggers, connect the annunciator leads to theNO and C contacts of the desired alarm (located on the relay alarm contacts on S2A-198 board). If it isdesired that the annunciator be deactivated until the alarm triggers, connect the annunciator leads to the NCand C contacts of the desired alarm.EXAMPLE: A customer wants a green lamp to be illuminatedat all times and wants a red lamp to illuminate and a speakerto sound when the Summary alarm triggers. The customerwould make the connections to the NC and C contacts on oneset of the Summary relay contacts between the speaker and apower supply. On the other set of Summary relay contacts,the customer would connect the NO and C contacts betweenthe green lamp and power supply, and would connect the NCand C contacts between the red lamp and power supply.
