ECC-50W-25V: 25V, 50 watt audio amplifier module. Adding a second speaker circuit increases the total ECC-50/100 power output to 100 watts or can also be used as a backup amplifier. Fire•Lite’s ECC-50/100 and ECC-50/100E are multipurpose emergency voice evacuation panels for fire applications, mass notification applications, or both. The Primary Operating Consoles (POCs) deliver 50 or 100 watts of audio power for distribution to up to eight speaker circuits (i.e. zones). The ECC-50/100(E) comes standard with a single speaker circuit and a built-in 25Vrms, 50 watt amplifier. A secondary 50 watt amplifier (ECC-50W-25/70V) can be added for single speaker circuit backup or to increase system capacity to two speaker circuits and an additional 50 watts of audio power. An optional ECC-CE6 module added to the ECC-50/100(E) will upgrade the system to a maximum of eight speaker circuit outputs. All speaker output circuits can be wired in either Style Y (Class B) or Style Z (Class A) configuration. The ECC-50/100(E) has fourteen field programmable messages (up to 60 seconds each), built-in field configurable pre- and post-announce tone generators and a fully supervised Notification Appliance Circuit (NAC) with 2.0 amps of synchronized NAC power. The ECC-50/100(E) includes three builtin Form-C relay contacts, (AC power, trouble and MNS active) a NAC follower input for triggering the on board NAC circuit and 500mA special application power. A built-in power supply with switch mode technology delivers operational power to the panel and an onboard battery charger supports charging up to 26AH batteries (ECC cabinet holds up to 18AH batteries).
