1.2 SYSTEM 

CONCEPT

MICROVAC is a single zone EWS unit, contained in a wall mounting cabinet with the
electronic functions located on a two PCBs, the Main PCB and the Keyboard/Display PCB.
High Powered versions and networked versions contain additional PCBs.

Figures 1.1 - 1.4 show block diagrams of the various MICROVAC control units.

The Main PCB provides tone generation, visual alarm output (strobes), 100V line output, FIP
and BGA inputs, auxiliary control inputs, auxiliary audio inputs,  and BGM attenuator
override and fault relay outputs.

The Keyboard/Display PCB provides the switches and LEDs for the front panel.

A microprocessor located on the Main PCB handles all control tasks.  In AUTO mode it
monitors the FIP and BGA control inputs for activation.  If one is activated then the beeper
will sound and if an "Initial Delay Before Alert" has been set this delay will occur and then the
ALERT tone(and optional speech message) will be generated on the 100V speaker lines and
the ALERT strobe output will be activated. This will continue for the "Alert to Evacuate
Delay" time, then the EVACUATE tone and speech message will be generated, and the
EVACUATE strobe output will be activated.

At any time, MANUAL mode may be selected from the front panel, and ALERT, EVACUATE
and PA may be manually controlled.

The warning signals are prioritised so that PA Speech is highest, Evacuate next highest, and
Alert lowest.

The microprocessor also monitors the control inputs, speaker lines, strobe lines, and the
amplifier and battery charger for fault conditions.

Non emergency functions of Paging and Background Music are also provided. These are
over-ridden in the event of an emergency.
