•
The Power On LED on the front panel remains on if battery power is supplied
•
Deactivate the AC Loss Relay on the FC-PSM(E) (immediate or 6 hour delay depending on S1 position)
Battery Trouble (low or no battery)
•
Turn on the Battery Trouble LED on the FC-PSM(E) module
Ground Fault
•
Turn on the Ground Fault LED on the FC-PSM(E) module
Microphone Fault
•
Turn on the Microphone Trouble LED on the front panel
Tone Generator Fault
•
Turn on the Tone Generator Trouble LED on the front panel
Message Generator Trouble
•
Turn on the Message Generator Trouble LED on the front panel
CMD1 or CMD2
•
Both inputs are supervised for open circuit condition when unit is programmed for Normally Open contacts,
otherwise supervision is provided by the host Fire Alarm Control Panel NAC output
Master Command
•
Polarity reversal circuit supervised for open and short circuits while in standby only.
Background Music
•
When background music option is enabled via DIP switch S5 switch 3, the VECP will constantly monitor the
external audio input RCA Jack. A fault condition will occur when the audio level input falls below acceptable
limits for 75 seconds. Both amplifiers and speaker wiring continue to be fully supervised
*
when background
music is output from the VECP. Note that when AC power is lost, the VECP will shut off background music
to conserve batteries. Background music requires installation of the FC-PSM(E) module. (Not UL approved
for use when the VECP is powered via TB3).
*
Note that when the 70.7 V
RMS
Transformer Module is installed, the use of background music is not
permitted.
Amplifier Fault
•
Both amplifiers are constantly monitored for proper functionality. Should either amplifier fail, the AMP
SUPR LED will turn off and the circuit Trouble LED will turn on. When the system is configured for backup,
failure of the primary amplifier will cause the backup amplifier to be switched in.
NAC (Speaker) Output
•
The wiring to each amplifier is supervised for opens and shorts at all times in standby and while in alarm or
when background music is enabled
*
. A wiring fault will cause the circuit Trouble LED located on each ampli-
fier module to turn on. It should be noted that the green AMP SUPR LED may remain on for wiring faults.
*Note that when the 70.7 V RMS Transformer Module is installed, the use of background music is not
permitted.
Power LED
•
When external power is used to power the VECP [FC-PSM(E) module not installed], a loss of input power at
TB3 will turn off the Power On LED.
Internal Power Supplies
•
Power fed to the amplifiers from the main circuit board is fully supervised. Should standby or alarm power
feeds to either amplifier fail, the unit will go into trouble.
Note that a power trouble on one amplifier will not affect the power to the other amplifier.
