Relay Pulse
Check This test may be used to verify connections to the alarm or cue relays. Each relay, as it is
tested, will energize and de-energize about once per second. Use the following steps to
check these connections:
1. First, verify that each relay is set either to ON or OFF. Relays placed in the nonvolatile
"Follow Warning" setting will not respond to the Pulse command used in this test.
2. From the DTMF Level Set screen, press the right-arrow button to display the Relay Pulse
Check screen.
3. Press ENT to display the Relay 1 Check screen.
4. The Relay Check screen will indicate that the relay is On or Off as it switches on and off
about once per second. At the same time, a user should see the ohm-meter reading
between the output contacts alternate between zero and (virtually) infinite.
5. Press the right-arrow button to test the remaining cue relays and the alarm relay.
6. Press ESC to return to the Relay Check screen.
