3b. The alarm relay is now being simulated. In the example to the left, alarm 1 has been set to Open. This means that the relay is not ener- gized (i.e. off). The alarm will remain open until either Exit 1 or Edit 4 is pressed or the test is concluded by timeout. The default value for the timeout is 10 minutes, so after 10 minutes, the alarm would go back to normal operation and the display will return to the main menu. To configure the timeout option, see Section 5.5.

If the displayed alarm action is not as desired, press the Edit 4 key and the next screen will allow changing it. Use the arrow keys to change the display as needed, and press Test 4 to enter the change. Press Esc 3 to cancel the change in the value and con- tinue simulating the previous action.

NOTE

Alarm relays may be simulated in the energized (Closed) position or the de-energized (Open) position.
