Keri Systems KWX-9A Specsheet

KWX Series

Wireless Transceivers

• Provides wireless RS-485 networking of PXL-500 Tiger II Controllers

• Allows networking of controllers in applications where cabling is difficult or impossible

• 915 MHz and 2.4 GHz models for worldwide compliance, no site license required

• Range up to 300’ (91m) with 915 MHz, up to 180’ (55m) with 2.4 GHz

• Range can be extended with optional antennas

• Can be used in conjunction with cabled controllers in the same network (mix and match)

• Built in signal strength indicators

Keri’s KWX Series Wireless Transceivers provide maximum flexibility and ease of installation in access
controller network architecture. Designed for any installation where Keri PXL-500 Tiger II Controllers will
be distributed around the facility or in clusters, these wireless transceivers can transmit RS-485 data
between controllers at up to 300’ (91m), or even longer with one of several optional antennas.
Whether it is to avoid costly trenching across a parking lot to reach other buildings or gates, to avoid a
long cable run within a building, or simply to manage all access control points within a single site in
the Doors software, wireless data transmission provides the solution.

Cabled and wireless and controllers can both be installed together in single controller network (mix
and match), allowing the customer to choose which connection method best suits each controller
location. Because transceivers can be placed up to 100’ (30m) from the controller, wireless transmission
range between controllers can be optimized by proper positioning of the transceivers to avoid
interference from building materials such as heating and air conditioning ducts, extending the
transmit/receive distance up to 500’ (150m) for 915 MHz systems and 380’ (115m) for 2.4 GHZ
systems, under ideal, line-of-sight conditions. Several antenna options can also increase distance or help
penetrate extra thick building materials or other objects. To avoid interference between two or more
distinct Keri access systems that would be located within the operating range of the transceivers,
adjacent customers can each use separate frequencies, 915 MHz vs. 2.45 GHz.
