Installing The NC-500 Pendant

Overview
A patient wears the Pendant on a lanyard around the neck. If the patient needs assistance, he
or she presses the button, and the Pendant sends a message to the Nurse Call and
Emergency System Central server.
Figure 31 shows the front of the Pendant and its features, which include:
•

7.2 LED Status Indicator
Fast green blinking:
The Pendant is looking for an ultrasound device.
Medium green blinking:
The Pendant is sending a message over the network.
Slow green blinking:
The Pendant is waiting for a response to the message.
One red blink:
The current operation has failed.
Fast green blinking followed by a red blink means that the Pendant failed to find an ultrasound
device. Even if the Pendant cannot find an ultrasound device, it will still send the message.
The Pendant uses two methods to send a message: it first sends a unicast message, and then
a broadcast message if the unicast message fails.
1. Unicast: the Pendant waits to receive a confirmation from the Nurse Call and Emergency
System Central server that the message was received. The LED blinks red once if the
Pendant does not receive a reply.
2. Broadcast: the Pendant does not wait to receive a reply. This means that if the broadcast
message fails, the LED does not blink red. It simply blinks slow green during the
broadcast message, and then stops.
