4.3 Indicators
Steady when a fault condition is present on the EWCIE. Indicator is
latched if there is a system fault.
Steady when the EWCIE is preventing from functioning due to a
hardware fault or communications between the Front Panel Switch and
Indicator Card and the amplifier(s) has been lost. Indicator is latched.
Steady when any of the following conditions are present:
Loss of mains voltage
Loss of backup batteries
Loss of battery charger or charger voltage outside allowable range
Fault with the backup batteries – high internal resistance, high temperature, faulty connections
Otherwise the indicator is off.
Steady when there is a fault associated with the speaker circuit (short or
interruption), strobe circuit (short or interruption) or amplifier, otherwise
off.
Steady when power is available to the EWCIE, flashing when mains voltage has not been
detected, otherwise off.
Steady when the EWCIE is in the Manual mode and the EWCIE is being controlled.by an
operator. When the MANUAL MODE indicator is Off, the EWCIE is in the AUTO mode, In
the AUTO mode, the EWCIE will respond to an alarm signal from the connected fire alarm control panel.
Steady when the EWCIE has been silenced from the fire alarm control panel.
Steady when there is a fire alarm condition present on the connected fire alarm control panel.
If the EWCIE is in the AUTO mode, then the EWCIE will respond to the alarm signal as per
the amplifier digital inputs (section 5.2) and DIP switch settings (section 5.6).
Indicator flashing at ½ Hz when the alert signal has been activated as a result of the EWCIE
responding to an alarm signal (from a connected fire alarm control panel) or operation of
the ALERT control. If the EWCIE is in the TEST condition, the alert signal is NOT broadcast.
