The ASC Edge:
Outstanding Multiplex Advantages
Using Ademco's motion detectors for multiplex system is a smart and sensible thing to
do. Whether it's a commercial or residential installation, these newest sensors offer you
the following cost-saving benefits:
Point ID identifies the exact location of the
intruder. And with the built-in Remote Point Module, the cost is less than a separate
module and sensor.
Ademco's patented Global Polling technology
senses alarms up to 8 times faster than conventional multiplex.
Ademco's unique 2-wire multiplex reduces
installation costs over conventional 4-wire hardwire and multiplex approaches:
-- Wire cost is reduced and less than half the number of connections are necessary
-- No more need to home run wiring
-- Each sensor draws super low currant, reducing power & battery requirements on large
installations while allowing for longer wire runs or smaller gauge wire
