DTMF Setup This test allows the setup of DTMF tone levels and verification of connections to cue
equipment. Use the following steps to set the DTMF level:
a. From the Audio/Video Check screen, press the right-arrow button to display the
DTMF Setup screen.
b. Press ENT to display the DTMF Test Tone screen and begin output of the DTMF
test tones. The tones (actually tone-pairs) are played out at about one-second
intervals from 1 through 9, 0, *, #, A, B, C, D, and then repeating.
c. Press the arrow buttons to adjust the volume. Up-arrow or right-arrow to increase
volume, down-arrow or left-arrow to decrease volume. The number of black
squares on the LCD indicates the current volume.
d. Press ESC to return to the DTMF Setup screen or ESC to return to the
Installation Testing screen.
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:
a. 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.
b. From the DTMF Level Set screen, press the right-arrow button to display the
Relay Pulse Check screen.
c. Press ENT to display the Relay 1 Check screen.
d. 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.
e. Press the right-arrow button to test the remaining cue relays and the alarm relay.
f. Press ESC to return to the Relay Check screen.
