Chapter 4 - OPERATION
Section 4-1- Introduction
This chapter describes the operating characteristics of the SP40/2 panel. Included is
information about the following SP40/2 panel features:
• Operator's Console
• Supervision
• Digital Voice Section
• Audio Notification Appliance Output Circuit Supervision
• Amplifier Supervision
• Actions that Initiate Alarms
Section 4-2 - Operator’s Console
The operator’s console includes a microphone, an AUDIBLE TROUBLE SILENCE Switch, an AC
LED, a TROUBLE LED, and a STROBE ALARM LED. Opening the enclosure door accesses the
operator’s console.
Section 4-3 - Supervision
A TROUBLE LED indicates that the supervisory functions have detected a malfunction in the
panel. When a trouble condition is detected, the panel may not be able to receive and/or
remember message requests from the control panel. The installer and/or user must make sure
that any message requests to the panel during a trouble condition are reactivated if necessary,
when the panel returns to normal.
If a trouble condition is detected by any of the supervisory functions, the internal sounder will
operate, the panel Form C TROUBLE relay (normally energized) will change state, and the yellow
TROUBLE LED will turn “ON”. The Trouble Status Relay (TB3-4, 5 and 6) must be properly
connected to and used by the control panel to indicate a system trouble. At the same time one of
the yellow trouble location LEDs will identify the location of the trouble condition. The internal
sounder can be silenced for 20 minutes by depressing the “Trouble Acknowledge” Switch (SW1).
Any subsequent troubles will cause the sounder to be activated. If a trouble condition is indicated,
follow the procedures in Chapter 7 "Troubleshooting”.
WARNING: DO NOT LEAVE THE PANEL IN A TROUBLE CONDITION, AS IT MAY NOT
PLAY WARNING MESSAGES WHICH COULD RESULT IN PROPERTY DAMAGE AND
SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS. IF THE PANEL INDICATES A
TROUBLE CONDITION: (1) PROVIDE UL REQUIRED ALTERNATIVE SIGNALING AND (2)
HAVE QUALIFIED SERVICE PERSONS IMMEDIATELY REPLACE UNIT(S) THAT HAVE
MALFUNCTIONED.
