Electrical Installation:
Fire Safety Model ITS4846A 1.4 GHz Remote Antennas are Listed for use within "Other
Spaces Used for Environmental Air (Plenum)" per NFPA70: 2011, Article
300.22.
Note: The term "plenum" as used in Article 300.22 Section C correlates with the
use of the term "plenum" in NFPA 90A-2009, Standard for the Installation of Air-
Conditioning and Ventilating Systems, and other mechanical codes where the
plenum is used for return air purposes, as well as some other air-handling
spaces. The area above dropped ceilings is an example of plenum space.
Interface Connections:
Control Signals RJ-45 Female Socket.
Core AP 75 Ohm Coaxial Cable
Connector
One standard 75 Ohm connector is provided for the coaxial cable on which RF
and DC sense signals are carried to the Remote Antenna.
Local Antenna Connections (two) Two SMA-style connectors.
