Settings
SN1-1/2/3 Sets the initial delay before the message starts to
play. The tone sounds during this delay. There
are eight options.
Off | Off | Off = No delay
On | Off | Off = 4 second delay
Off | On | Off = 8 second delay
On | On | Off = 12 second delay
Off | Off | On = 16 second delay
On | Off | On = 20 second delay
Off | On | On = 24 second delay
On | On | On = 28 second delay
SN1-4/5 Sets the delay between repetitions of the
message. The tone sounds during this delay.
There are four options.
Off | Off = 4 second delay
Off | On = 8 second delay
On | Off = 12 second delay
On | On = 16 second delay
SN1-6 Sets the message play mode. There are two
options.
Off = Message off
On = Message on
SN1-7/8 Sets the number of times the message plays.
There are four options.
Off | Off = 1 play
Off | On = 3 plays
On | Off = 2 plays
On | On = Continuous play
SN2-1/2/3 Sets the evacuation tone. There are eight
options.
Off | Off | Off = Temporal slow whoop
On | Off | Off = Hi-lo
Off | On | Off = Horn
On | On | Off = Bell
Off | Off | On = None
On | Off | On = Chime
Off | On | On = None
On | On | On = 1 kHz sine
SN2-4 Sets the diagnostics mode. With diagnostics ON
the last fault condition is displayed even if the
fault is no longer present. There are two options.
Off = Diagnostics off
On = Diagnostics on
SN2-5 Not used
SN2-6 AC power failure report delay. There are two
options.
Off = No delay
On = 6-hour delay
SN2-7 Batteries. There are two options.
Off = Batteries are not connected
On = Batteries are connected
SN2-8 Microphone. There are two options.
Off = Microphone is not connected
On = Microphone is connected
Jumper settings

Options
Aux +24 Vdc output
Terminals TB2-4, -8, -9, and -10 provide a maximum of 200 mA
of regulated 24 Vdc power for auxiliary functions. Do not
exceed a combined load of 200 mA on these terminals. These
terminals are for connection to ANS accessory modules and
listed general signal devices only and are not for use with fire
protective signaling applications. Terminal TB2-4 activation is
programmed in the U6 EPROM chip. Standard chips are
programmed for TB2-4 to go active (+24 Vdc) under the
following conditions:
•
Aux signal active
• Aux audio enable
• Bell circuit active
• RSI active
Reprogramming of these functions must be done at the factory
and requires replacing the EPROM U6.
Aux audio source connection
Terminals TB2-1 and -2 allow connection of an aux audio
source from additional paging equipment to augment an
existing paging system. This option is not intended for
continuous signal input, but may be used for paging
applications. For such an operation the aux audio enable input,
TB2-6, must be powered from the interrupted V+, TB2-9. This
ensures that in the event of an alarm, the aux audio will not
override the evacuation signal. See Figure 9 for connection
details. Use of an ANSAUX Audio Transponder Module may
be required for some audio sources (to match the auxiliary
audio line signal.)
Optional supervisory circuit
Terminals TB3-1 and -2 can be used to connect a supervisory
circuit from the FACP to the ANS. In place of normal
supervision via the notification appliance circuit, an alternate
method may be employed using any supervisory circuit from
the FACP. TB3-1 and -2 provide a normally closed connection
to the EOLR on TB3-3 and -4. The relay contact in the circuit
opens on any trouble condition and reports an open circuit
trouble to the FACP.
