en 399

Volume override output key can be assigned to a zone (see section 45.2) and becomes active when a call with a priority equal to or higher than 32 is sent to the zone. See figure 47.37 for an overview of the Action programming page for a Volume override output key.

47.3.31 System fault

The System fault action is intended for control outputs and call station keypads or call station keypad kits. The key/input itself is not used by this action; only the second output or yellow indicator attached to the key is activated while a system fault is present. System faults are:

•Configuration file error

•Flash card data error

•Flash card missing

•No valid configuration file found

•Processor reset

47.3.32 Zone status

The Zone status action is intended for LBB4434/00 Call Station Keypad Kits. The key/input itself is not used by this action; only the indicators/outputs attached to the key is activated. The Zone status action activates the indicators/outputs belonging to the key if certain conditions are met. It serves two purposes:

1If a call is made to at least one of the configured zones or zone groups with a priority higher than or equal to the configured priority, then the second output for this key indicator (normally a yellow LED) is activated on an LBB4434/00 keypad kit. If it is used to indicate an emergency call in these zones or zone groups, then a red LED should be connected to this output. Preferably a dedicated indicator per emergency zone is used. The color red for this purpose is defined in most emergency sound system

standards, e.g. EN54-16. If the defined priority is set to 224 the Zone status indicator lights if an emergency call (priority equal to or higher than 224) is made to that zone or zone group. See figure 47.31 for an overview of the Action programming page for a Zone status key.

2If a fault is present in the zone that is configured for this action, then the first output for this key indicator (normally a green LED) is activated on an LBB4434/00 keypad kit (flashing). This indicates that one or more fault events are present for units or connections that are associated with that zone. A yellow LED should be connected to this output. This color is defined in most emergency sound system standards, e.g. EN54-16. A zone fault is a fault that causes that (part of) a zone cannot be reached for calls anymore. This indication is the collection of

16 different faults that may cause a problem to reach a zone completely, like line faults, overheat and overload faults. If a fault is internally solved by e.g. a spare amplifier that takes over a defect amplifier, this will not result in a zone related fault but only in a more specific fault about the reason for the spare amplifier switching. Also in case of redundant loudspeaker line configuration, a single GroupAFault or GroupBFault will not contribute to the zone fault status, since the zone is still addressable with a level of -3 dB. This assumes that the loudspeakers in that zone are evenly divided between group A and group B. The zone fault status is de-activated when all faults that contribute to that zone fault status have been resolved, even if they are not yet reset.

The following faults contribute to the Zone fault status (see section 54, the Fault events list for details):

•Amplifier failure

•Amplifier failure or overload (for LBB4428/00 only)

•Amplifier initialization failure

•Amplifier loudspeaker line failure (for single loudspeaker line supervision)

•Amplifier loudspeaker line failure (for multiple loudspeaker line supervision)

•Amplifier missing

•Amplifier overheat: muted

•Amplifier overload

•Amplifier short circuit
