It is worth your while to use ADEMCO's intelligent motion detectors for multiplex systems. Not only are they smarter than ever, but they provide ample opportunity to greatly reduce your overall initial installation costs! These sensors offer you the following benefits whether you want a commercial or residential installation:

• Point ID identifies the precise spot in which the intruder is located with either a DIP Switch Address (4278EX) or a Serial Number Address as distinctive as fingerprint (4278EX-SN). And with the built-in Remote Point Module, the cost to you is lower than a separate module and sensor.
• ADEMCO's patented Global Polling technology can sense intruders and sound off alarms up to 8 times faster than any other conventional multiplex.
• ADEMCO's unique 2-wire multiplex gives you a large reduction in installation costs over conventional 4-wire hardwire and multiplex approaches:
  • Wire cost is lessened and less than half the number of connections are required
  • No more need to home run wiring
  • Each sensor uses unbelievably low current, reducing power & battery necessities on large installations while giving you the option for using longer wire runs or smaller gauge wire
