5. Operation
5.1 Introduction
This chapter describes the operating characteristics of the SP40S Multi-Function Facility
Communication System. Included is information about the following panel features:

Supervision

Audio Notification Appliance Output Circuit Supervision

Amplifier Supervision

Actions that Initiate Alarms
5.2 User Interface
The User Interface on the SP40S displays the basic status of the unit as well as providing a
limited number of user controls. The User Interface includes a Microphone and the manual
activation or recording of the eight messages. There is also a button to silence the audible
trouble indicator. Status indicators include POWER ON, SYSTEM TROUBLE, AC
TROUBLE, ALARM ACTIVE, and STROBE ACTIVE (see Figure 3).
5.3 Supervision
A SYSTEM 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 broadcast messages from the control panel.
If a trouble condition is detected by any of the supervisory functions, the internal sounder
operates the panel Form C TROUBLE relay (normally energized), changes state, and the
yellow SYSTEM TROUBLE LED turns “ON.” The Trouble Status Relay (TB2) 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 identifies the location of the trouble
condition. The internal sounder can be silenced for 20 hours by depressing the “Trouble
Acknowledge” Switch (SW1, on the User Interface). Any subsequent troubles cause the
sounder to be re-activated. If a trouble condition is indicated, follow the procedures in
Chapter 8 "Troubleshooting.”
An AC Loss can be selected to be reported as a system trouble after 170 minutes (SW2-
Position 2 = ON). This is desirable for off-premise trouble reporting. If SW2-Position 2 is
OFF, AC Loss is reported as a system trouble after 30 seconds.
WARNING: DO NOT LEAVE THE SP40S PANEL IN A TROUBLE CONDITION, AS
IT MAY NOT PLAY WARNING MESSAGES, WHICH COULD RESULT IN
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
