2.4.18.7
Fixed Map Display
Display shall consist of a geographic, tabular, or combination geographic
and tabular representation of monitored zones in which status of each zone
is displayed by light-emitting diode zone status indicators which shall be
multiplexed for reduced power consumption. Display shall contain an
integral specific-purpose processor assembly which shall decode map bus
data and drive the zone status indicators. Under continuous central
processor automatic control, integral processor assembly autonomous
control, or local operator control, each map display shall:
a.
Under Monitor and Control Unit Control:
(1)
Annunciate zone status changes; and
(2)
Continuously display current zone status.
b.
Under Integral Processor Assembly Autonomous Control:
(1) Continuously supervise map bus lines from the monitor and
control unit; and
(2) Annunciate failure of communications from the monitor and
control unit.
c.
Under local operator control: Self-test processor assembly
functions and zone display status indicator operation.
d.
Conform to the following general requirements:
(1) Size: [1232 mm W by 757 mm H by 38 mm D] [48.5 inches W by
29.8 inches H by 1.5 inches D] [_____];
(2)
Mounting:
Wall;
(3) Input power: 9 to 15 volts dc at 2 amperes for each
processor assembly;
(4)
Storage temperature:
Minus 55 to plus 71 degrees C;
