Power failure

In the event of a total system power failure, at least 50% of the equipped lines are switched to separate
RJ11 connectors on the appropriate MDF. Lines 1 and 2 are power-failed to two RJ11 connectors on the
base unit MDF. Lines 5 and 6 are power-failed to two RJ11 connectors on the first Extension module MDF,
lines 9 and 10 to two RJ11 connectors on the second Extension module, lines 13 and 14 to two RJ11
connectors on the third Extension module and lines 17 and 18 to two RJ11 connectors on the fourth
Extension module.
Standard two-wire phones are wired to these connectors and they can make and receive calls when the
system is powered down. The connectors can be wired to separate standard telephones or paralleled with
extensions equipped with standard phones.
ECX 2000 and ECX 1000 digital telephones cannot be used as power failure phones.
All power failure phones must be standard DTMF telephone sets such as the ECX
100.
