5.4 Zones/Panel Circuits Status Holding Registers

Each of the zones/panel circuits status holding registers are divided into an upper and lower byte as described below and in
• Upper Byte: The upper byte contains general status information about the zone or panel circuit.
• Lower Byte: The lower byte is primarily used when bit 11 in the upper byte is a '1' (or active). When bit 11 is a '1', refer to
Appendix C, "MODBUS-GW Active Event Types"
byte will be all 0's if the zone/panel circuit is not in an active state.
Specifically, the lower byte contains the actual active event for this zone or panel circuit. An active state is defined in this
gateway as any Fire, Security, Critical Process, Medical, Mass Notification, or Supervisory alarm state. If the zone or panel
circuit is not present in the panel programming, all bits in the lower byte will contain a '1' or the value 'FFH'.
Bit No.
Bit Name Ack Block
When individual upper byte bits are set to 1, the following definitions apply:
• Ack Block (Bit 15): All events on this zone/panel circuit, other than fire alarm, are
• Prealarm (Bit 14): The zone/panel circuit is in a prealarm state.
• Trouble (Bit 13): The zone/panel circuit is in a trouble state.
• InActive (Bit 12): The zone/panel circuit is not active.
• Active (Bit 11): The zone/panel circuit is active and there will be an active event type
• Enable (Bit 10): The zone/panel circuit is enabled.
• Disable (Bit 9): The zone/panel circuit is disabled.
• Ack Fire Alarm (Bit 8): The fire alarm on this zone/panel circuit is acknowledged.
