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.

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.

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.

Press

ESC to return to the Relay Check screen.
