Visual and audible trouble alarm indicated at remote annunciator panel.

Trouble signal transmitted to [municipal connection.] [remote station.] [central station.]

Manual acknowledge function at fire alarm control panel silences audible trouble alarm; visual alarm is displayed until initiating failure or circuit trouble is cleared.

Alarm Sequence of Operation: Actuation of initiating device places circuit in alarm mode, which causes the following system operations:

Sound and display local fire alarm signaling devices with [march time] signal.

Transmit [non-coded] [zone-coded] signal to [municipal connection.] [remote station equipment.] [central station.]

Indicate location of alarm zone on fire alarm control panel [and on remote annunciator panel].
