The holding register address and the bell circuit contained in the address is detailed in
Table 7.18, “Bell Circuit Holding Register Addresses”
7.22.6 Bell Circuits Device Type Input Registers
Each bell circuits device type holding register address consists of two bytes as defined in
Table 7.19, “Bell Circuits Device Type Input Register Bit Definitions”
representing a bell
circuit as shown in
Table 7.20, “Bell Circuit Device Type -Input Register Addresses”

When individual upper byte bits are set to 1, the following definitions
apply:
Ack Block
(Bit 15): All events on this bell circuit, other than fire alarm, are
acknowledged.
Prealarm
(Bit 14): The bell circuit is in a prealarm state.
Trouble
(Bit 13): The bell circuit is in a trouble state.
InActive
(Bit 12): The bell circuit is not active.
Active
(Bit 11): The bell circuit is active and there will be an active event
type in the lower byte.
Enable
(Bit 10): The bell circuit is enabled.
Disable
(Bit 9): The bell circuit is disabled.
Ack Fire Alarm
(Bit 8): The fire alarm on this bell circuit is acknowledged.
