OPERATION

3.1 CONTROLS

3.1.1  AUTOMATIC - MANUAL - ISOLATE KEYSWITCH

The keyswitch selection defines MICROVAC's operating mode. In AUTOMATIC mode,
MICROVAC operates entirely automatically, and generates the tones in the sequence
described above in the event of the FIP or the BGA input going into alarm. This is the only
mode in which the key can be removed. MICROVAC should be left in this mode at all times
unless a building warden is attending to an emergency, or MICROVAC is being tested or
used for training.

In MANUAL mode the PA, EVACUATE, and ALERT pushbuttons are enabled, and will
generate the tones directly or allow the Microphone to be used. FIP and BGA inputs going
into alarm will result in the beeper sounding but no tones will be automatically generated.
This mode is intended for Manual control during an emergency or to broadcast verbal
messages to negate previous instructions in the event of a false alarm.

In ISOLATE mode the pushbuttons will illuminate the associated indicator but not generate
any tones. FIP and BGA inputs going into alarm will sound the beeper but not generate any
tones.

For a networked Microvac, one or more QE90 ECPs will be capable of selecting the
MANUAL or ISOLATE mode for the Microvac. When this happens, the MANUAL or
ISOLATE LED will flash with a flash-flash-pause cadence. The PA, EVACUATE, and ALERT
controls on the Microvac will not be enabled when it is being controlled remotely. If the
Microvac keyswitch is switched to manual 

and

 a remote QE90 which controls the Microvac

is also switched to Manual, the one to receive control will have been configured as part of
the factory programming.

3.1.2 PA 

PUSHBUTTON

The PA pushbutton has a toggle action : pushing it once will turn the PA function on, and
pushing it again will turn the PA function off. When the PA function is on, as indicated by the
yellow LED, PA announcements may be made by holding in the PTT button on the
microphone and speaking into the microphone.

Alternatively, if DIP Switch 2:1 is off pressing PTT on the microphone will activate the PA
function automatically.

The PA pushbutton does not operate in AUTOMATIC mode. In ISOLATE mode, the LED will
illuminate but no sounds will be produced.

3.1.3 EVACUATE 

PUSHBUTTON

The EVACUATE pushbutton has a toggle action : pushing it once will turn the EVACUATE
function on, and pushing it again will turn the EVACUATE function off. When the
EVACUATE function is on, as indicated by the red LED, the EVACUATE tones will be
generated and the EVACUATE strobe output turned on.
