Note:

Before testing, you MUST notify the
personnel in charge of the Fire Alarm
panel, since the test may disrupt normal
business operations. In addition, you
MUST notify the local Fire Department if
the department is connected to the
municipal tie.

Alarm Operation

Test the annunciator for alarm operation by:

  • Activating an initiating device on a zone

configured for alarm.

  • Confirming the normal alarm functioning of

the unit and the Control Panel.

The ALARM LED (LED on left) should glow red
for the appropriate zone.

Supervisory Operation

Test the annunciator for supervisory operation by:

  • Activating an initiating device on a zone

configured for supervisory.

  • Confirming the normal supervisory functioning

of the unit and the Control Panel.

The SUPERVISORY LED (LED on left) should
glow yellow for the appropriate zone.

Trouble Operation

Test the annunciator for trouble operation by:

  • Disconnecting a wire from a zone at the

Control Panel.

  • Confirming the normal trouble functioning of

the unit and the Control Panel.

The TROUBLE LED (LED on right) for the
appropriate zone should glow yellow.

Annunciator Supervision

Check annunciator supervision by:

  • Disconnecting the DATA line from TB1 on

the module.

  • The Control Panel indicates the trouble, but

if there are two annunciators on the system,
it does not tell which of the two is in trouble.

For more information on this supervision, see
the section on 

Troubleshooting on page 4.
