Board has the circuit that will reset the system
should the 3.3V supply exceed 3.6V .

Operator Control Panel

• Keyboard: The main operator input device
for choosing operating modes and settings is
the membrane keyboard panel. Tactile-feedback
mechanical switches allow the operator to set
modes and adjust power settings.
• Display Panel: Consists of 7-segment displays
and discrete dual colored LED's that will display
all controls and settings. LED display elements
are illuminated in a time division multiplexed
fashion; the illuminated LED display elements are
actually on less than half the time.
3.2.9

Activation Tones

Tone is generated for all activation requests, fault
detection and changes made on the Control Panel.
The System Controller generates the tone signal
(TONE_DRV), which is amplified by a driver.
The activation tone is adjustable and controlled by
an output from the System Controller, but alarm
tones are not adjustable and are set to generate a
tone greater than 65 dB.
There is circuitry to permit the Monitor to verify
the oscillation from voltage measured across the
speaker, which provides confirmation that the
speaker is indeed generating audible tones dur-
ing activation. RF output is inhibited should the
3-6
speaker drive current be absent or too low.

3.2.10 Activation Relay Connector

There is an Accessory Relay Connector, which
provides a relay closure (SPST switch) that may
be used for activating external accessories such as
smoke evacuation units.

Optional System Configurations

An eight-position configuration dipswitch (S2),
located on the Control/Display Board Assembly
(A4) allows a qualified service technician to
change some of the factory default settings. With
the exception of the DACview switch, which is
only effective in Test Mode, the configuration dip-
switch settings are only detected when power is
initialized, so any changes to the switch positions
will not be detected until power is cycled. Each
switch is OFF in the Down position and ON in
the UP position. (The system detects changes in
the DACview switch while power is on, so it is
treated differently.) Relevant information for the
configuration dipswitches appears in Section 4.8.
