10.3. EP ARM Testing Procedures
1.
WARNING!
Before you begin, disable the EP Control Panel and shunt all GCA's (per E06-018-2 and E06-017-2)
connected to the system before proceeding!
2. Connect the Analyzer to the EP ARM as shown in Figure 10.3-1 below.

3. Remove the 0Ω Shunt from the Analyzer. The supervisory current will be displayed as 20mA - 54mA, consistent
with Section 10.2.

Current 32mA
4. Record the EP ARM supervisory current reading for future reference, since subsequent tests will override
current test data.
5. Install the 0Ω Shunt onto the Analyzer. The display will read "Ready for Test." Reset the main EP Control Panel
if required to obtain a normal panel, and wait 60 seconds for the capacitor to charge.

6. Activate the EP ARM by initiating a detection input that will cause the control panel output to trigger the EP
ARM.

EP ARM PASSES
7. The current reading displays, along with "EP ARM PASSES" or "FAIL REPLACE ARM."
NOTE: The upper limit of each test range is provided to help you determine when a component is nearing the
end of its useful life and should be replaced. For the EP ARM, the first reading must be greater than or equal to
8, and the average of the three (3) test readings must be greater than or equal to 95% of 5.5 amps, or 5.225A.
If the average is approaching 5.225A, consider replacing the EP ARM.
