POWER RELAY TEST
CAUTION: Remove power connections on the Power Relay BEFORE testing.
Use Hold-To-Test Feature
- Press and Hold the test button until the Yellow Testing LED comes on.
- Use a Volt/Ohm meter to check that the Power Relays are activating.
Measure Power Relay Continuity
Remove power from the control panel and with a Volt/Ohm meter, check for continuity between the COM and NC connection of the power relay. It should read less than 5 ohms. If the reading is significantly higher or shows an open condition (OL), the power relay should be replaced.
