The NIFX fixed wireless transceiver is a three-button wall mounted switch module. It comes as a socket
version used for the connection of a handset or equipped with a pull-cord. Both variants of the NIFX
include a 125 kHz LF receiver and an NIRX 916 to 921 MHz Class 1 transceiver which is piggy-back
mounted on the circuit board of the NIFX. The fixed wireless transceiver switch modules can be powered
by two AA disposable alkaline batteries, or connected to an external 24VDC power supply. “NIFX Fixed
Transceiver” on page 156
The NITX mobile call transceiver can be attached to a wrist strap, or to a neck pendant. The NITX is
powered by an internal three volt replaceable lithium battery. It includes a 916 to 921 MHz transceiver
and a 125 kHz LF receiver for receiving the location update information from LF beacons. “NITX Mobile
Transceiver” on page 158
The NITX staff transceiver is identical to the NITX mobile call transceiver except for the button
functionality. The staff transceiver is carried by staff members and allows the staff member to cancel calls
initiated from wireless transceivers (NITX-BAB, NIFX-1AB and NIFX-1BB) through an LF transmission when
in close proximity of the wireless transceiver and provides the identification of the staff member
cancelling the call.
The NILF low frequency beacon includes a 125 kHz transmitter and can be extended with the piggy-back
mounted NIRX 916 to 921 MHz transceiver. The LF Beacon NILF is contained in a white plastic enclosure
with a slim design that is suitable for surface mounting on walls or at a door post. “NILF Low Frequency
Beacon” on page 173. The NILF can be powered by three C size disposable alkaline batteries, or
connected to an external 24VDC power supply (chapter 4‚ ‘System Power” on page 10)
