Fire Alarm Panel Battery Load Test

A connected 12v battery should read around 13 5v before ac is removed.

Fire alarm panel battery load test. Silence the alarm and trouble signals. Restore power to the heat trace controllers. Also note that you will need to move the positive test lead to the amp test lead port as shown in the pictures below. Wait for the reading to stabilize.

Record the alarm current reading on your test report. Initiate an alarm on the fire alarm system by triggering a device or zone. Replace the battery or conduct a load test of the battery. Turn off the max min setting on your meter.

In order to measure the load or current of a fire alarm circuit we must place the multi meter test leads in series with the circuit to be read. Battery test analyze 6 12 volt fire alarm batteries sla vrla gel agm batteries 3 ahr to 140 ahr. This is very important as it is impossible to do otherwise. Batteries need to be tested for charge discharge and load voltage.

In testing the charge of a battery the battery must be fully charged and then tested with a voltmeter. When you make the intelligent choice for ultimate reliability ease of use and simple implementation you are choosing the same tester used by the industry s leading nfpa compliance testing companies worldwide. Record the reading on your test report. Load test the battery based on the manufacturer s specifications for a discharge rate of 3 hours or more by applying the current indicated for the selected hourly discharge rate continuously until the terminal voltage decreases to the end voltage specified by the manufacturer.

Record the test duration and calculate the battery capacity including.
