2: Leds Visible With Door Open And Optional Dress Panel Removed (Figure 1-1 & Figure 1-2); Operation; 1: Fire Alarm - Fire-Lite Alarms FIRE COMMAND 25 Installation And Operating Instruction Manual

Operation

Tone Generator Trouble
This yellow LED turns on steady when one of the supervised tone generators fail or fall below acceptable levels.
Message Generator Trouble
This yellow LED turns on steady when the supervised digital message generator fails or falls below acceptable
levels.
REC (Record) - Located on Front Panel Trouble Silence Button
This green LED pulses once every second when ready to record one 60 second message or twice every second
when ready to record two 30 second messages. It turns on steady while recording and then pulses when five sec-
onds of recording time remains. The LED shuts off when recording time has terminated.
4.2.2 LEDs Visible with Door Open and Optional Dress Panel Removed (Figure 1-1 & Figure 1-2)
AMP SUPR - Supervision (Audio Amplifier Module)
This green LED (one on each amplifier), when on steady, indicates that the amplifier is fully functional. The
VECP constantly tests the amplifier to verify proper operation.
Circuit Trouble (Audio Amplifier Module)
This yellow LED (one on each amplifier) turns on steady when a trouble is detected in the amplifier or to indicate
an open or short circuit on the field wiring attached to the amplifier output terminals.
Ground Fault (Power Supply/Battery Charger Module)
This yellow LED turns on steady when a ground fault condition is detected on the system.
Battery Trouble (Power Supply/Battery Charger Module)
This yellow LED turns on steady when the battery is disconnected or battery voltage drops below an acceptable
level.
AC ON (Power Supply/Battery Charger Module)
This green LED remains on while AC power is within correct limits. If this indicator fails to light under normal
conditions, service the system immediately).
4.3 Operation
The VECP continuously monitors system status. When no system alarm or local trouble conditions exist, all LEDs
are off except the Power On LED located on the front panel keypad, the amplifier supervision LED(s) and the AC ON
LED located on the optional Power Supply/Battery Charger Module. The Notification Appliance Circuits (speakers)
are off and all relays are in their normal state. Alarm and local troubles are annunciated by the VECP's LEDs.
4.3.1 Fire Alarm
The Voice Evacuation Control Panel will, upon detection of an alarm condition (either CMD1 or CMD2 Inputs):
Turn on the front panel Alarm LED steady
Activate (reverse polarity) Master Command Output Bus
Turn on the appropriate Notification Appliance Circuit speakers (depending on CMD input source)
Turn on the appropriate Audio Amplifier
Transmit the tone before message if programmed (repeating tone number of times programmed)
Transmit the appropriate (CMD2 can be programmed to transmit secondary 'nonfire' message) digital
voice message (repeating message number of times programmed)
Transmit the tone after message if programmed (repeating tone number of times programmed)
Transmit a primary evacuation tone only (if programmed)
