CHAPTER 1
Product Description
The FIRE•COMMAND•25/50 Voice Evacuation Control Panel (VECP) is a single-channel, 25 watt, 25 V
RMS
, emer-
gency voice evacuation panel. The panel includes dual field programmable message capability (up to 60 seconds)
and an integral microphone. The base configuration requires that 24 VDC regulated power be provided to the
FIRE•COMMAND•25/50 for operational power. A separate custom power supply module with battery charger is
available and may be installed as an option to provide the 24 VDC regulated power. An optional second 25 watt
amplifier is also available for backup purposes or to provide an additional channel of 25 watts. Optional 70 V
RMS
conversion modules are also available for installations where 70 V
RMS
speakers are to be installed or already exist.
The modular design allows for ease-of-serviceability.
Two Command Input Circuits can be independently field programmed for activation by an FACP Notification Appli-
ance Circuit reverse polarity or by closure of a supervised normally open contact. Terminals are provided for NAC
input and output to allow installation of the FIRE•COMMAND•25/50 anywhere along the NAC circuit being used to
activate it. Options via the Command Inputs allow one 60 second message over both amplifiers simultaneously or by
selecting amplifiers individually, two 30 second messages may be selected.
Significant technological enhancements set the FIRE•COMMAND•25/50 apart from other voice panels. These
enhancements include full supervision in both active (alarm or music) and standby conditions. Supervision is pro-
vided for:
✓
amplifier outputs
✓
field wiring (shorts and opens)
✓
message generator
✓
all tone generators
✓
microphone
If the message generator fails, the system automatically reverts to the primary tone generator. If the primary tone
generator fails, one of three backups become enabled.
Power is fed independently to each amplifier so that a short circuit in one amplifier will not shut down the other. Full
output power of 25 watts per amplifier is generated while in a low battery condition. Power is not diminished when
the 70 V
RMS
option is installed. Audio is amplified from modern integrated circuits as opposed to transformer tech-
nology. This provides for very low signal distortion for crystal clear audio.
Primary applications for the FIRE•COMMAND•25/50 include nonhigh-rise structures such as restaurants, schools,
auditoriums, places of worship, buildings with occupancies over 50, etc. The FIRE•COMMAND•25/50 is designed
to interface directly to addressable or conventional fire alarm control panels or act as a complete stand-alone unit.
