9.6.5 NIFX Fixed Transceiver
The NIFX series fixed transceiver is a wireless teleCARE IP switch module which is available
as socket module or pull cord module. It has 3 function buttons, a white plastic body and
includes a spacer for surface mounting. The pull cord version includes the cord with two red
balls but no socket. It is capable of functioning as a stand-alone fixed transceiver or in
combination with standard hard-wired teleCARE IP switch modules when external power
supply is used.

Every fixed transceiver requires an NIRX transceiver which is piggyback mounted on the
NIFX board. Each NIRX has a unique identity (ID) and this ID is transmitted with every event
from the fixed transceiver.
The fixed transceiver requires 2 x 1.5V AA disposable batteries. An automatic low power
warning is transmitted by the fixed transceiver if the battery voltage falls below an
acceptable level of 2.4V.
The battery voltage is continually monitored and if low voltage is detected a “low battery”
alarm is transmitted as part of the heartbeat transmission of the unit. Under normal
circumstances the battery life is approximately one year.
The fixed transceiver sends a “Heartbeat” signal at 4 minute intervals. If the wireless server
does not receive the heartbeat signal within a predetermined period then it is assumed that
the transceiver has failed or is missing and an alarm will be automatically generated.
The fixed transceiver includes 1 red button, 1 yellow button, 1 green button and 1 pull cord
switch. The buttons can activate a normal, assistance, emergency call and a staff presence.
The pull cord version generates a bathroom call and is supplied with a permanently
attached 50mm length of pull cord. The pull cord is supplied as a kit consisting of a 2m
length of red plastic covered nylon cord and two red balls.
The pull cord balls are designed so that the two halves of the ball break apart if the cord is
pulled with excessive force. This prevents injury and damage to the switch. The two halves
of the ball can be simply snapped back together.
