The Acknowledge switch (ACK), silences the internal buzzer of the panel. Any

"ACK" switch is depressed, will return to normal. Should a second alarm
activate the same points (signal circuit or relay programmed to restore on
Acknowledge) which have been returned to normal will re-activate.

WARNING !
Do NOT reset the system until the authority having jurisdiction
has authorized reset.
Reset Switch
The Reset switch (RESET) removes power from the initiating devices for a
period of four (4) seconds. Power is temporarily removed from the S+ S-
terminals. Any devices latched into alarm should return to the normal condition,
provided the cause of alarm has been eliminated. The signal circuits, city tie,
alarm relay and/or supervisory relay will restore, and the panel will return to the
normal quiescent condition.
Signal Silence
The Signal Silence switch (SIGNAL SILENCE ) will silence (i.e. return to
normal), any circuit or relay that is programmed to restore on signal silence.
The signal silence switch is an alternating action switch. Pressing the signal
silence switch will return the silenced circuits to an active state.
