4278EX / 4278EX-SN

It makes sense to use Honeywell’s smart motion detectors for multiplex systems. Not only are they smarter than ever, but they provide the opportunity to reduce your overall installation costs!

The 4278EX and 4278EX-SN can be used with any Honeywell alarm system that supports Multiplex Addressing, including the VISTA-40, VISTA-50, 4140XMP, and VISTA-100. The 4278EX may also be used with the 5140XM. Whether it’s a commercial or residential installation, these sensors offer many benefits.

Features:

• Built-in Remote Point Module with Point ID identifies the exact location of the intruder with either a DIP Switch Address (4278EX) or a Serial Number Address as distinctive as a fingerprint (4278EX-SN)
• Honeywell’s patented Global Polling technology senses alarms up to eight times faster than conventional multiplex
• Honeywell’s unique two-wire multiplex reduces installation costs over conventional four-wire hardwire and multiplex approaches by reducing both wire costs and the number of connections
• Super low current, reduces power and battery requirements on large installations
