Section 1: Product Description
The Fire•Lite Emergency Command Center ECC-50/100 is a single channel, 50 watt, 25 V
emergency voice evacuation panel that may be used for fire applications, mass notification applica-
tions, or both. The ECC-50/100 comes standard with one speaker circuit. The panel provides the
ability to record fourteen field programmable messages (up to 60 seconds each) with an integral
microphone or from an external audio source. An integral power supply with battery charger sup-
plies operational power. A 50 watt audio amplifier is built into each panel. An optional second 50
watt amplifier (ECC-50W-25/70V) is also available for backup purposes or to provide an additional
50 watts. The backup amplifier is available in either 25 volts or 70 volts depending on which appli-
cation is necessary.
Automatic activation of the ECC-50/100 by an FACP is possible via eight Command Input Circuits
(CMD) or via the ACS/ANN Bus serial communications link from the MS-9600(UD)LS and
Two Command Input Circuits can be independently field programmed for activation by an FACP
Notification Appliance Circuit reverse polarity or by closure of a supervised normally open contact
and six Command Input Circuits activate on contact closure. CMD 1 and CMD 2 provide terminals
for NAC input and output to allow installation of the audio panel anywhere along the NAC circuit
being used to activate it.
If the message generator fails, the system automatically reverts to a backup tone generator.
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 50 watts per amplifier is generated while in a low battery con-
dition. Power is not diminished when the optional 70 V
is amplified utilizing modern integrated circuits as opposed to transformer technology. This pro-
vides for very low signal distortion for crystal clear audio.
Primary applications for the audio panels include protecting structures such as military facilities,
restaurants, schools, auditoriums, places of worship, buildings with occupancies over 50, etc. The
ECC-50/100 is designed to interface directly to addressable or conventional (CMD inputs 1-8) fire
alarm control panels or can be used with the ECC-50/125DA panel to distribute audio in systems
that require more than 100 watts.
For Canadian applications, refer to Appendix C on page 103.
