The Trilogy Networx Expander extends the coverage area of a Generation 2 SeriesAL-IME2 Gatewayto Trilogy Networx Locks within a PC network, allowing greater distances for the placement of up to a maximum rated capacity of 63 networx locks per Version 2 Gateway.Typically introduced into the network when a Gateway does not provide sufficient signal strength to a particular area, it is designed to extend coverage and thus facilitate communications with a wireless lock or a group of wireless locks. The AL-IME2-EXP Expander must be used with a Generation 2 AL-IME2 Series Gateway, but can be intermixed in an existing system that includes older non-version 2 Gateways.
